FIRST WORD

The red, green and grey

Labour has revealed five ‘golden rules’ on the green belt with which it will campaign in the approach to the General Election (GE) in June, November or January 2025 (your guess… etc). It leads with a commitment to prioritise brownfield development, followed by an emphasis on the newly-coined ‘grey belt.’

The grey belt is the unlovely bit of the green belt, upon which abandoned warehouses, derelict car showrooms and other post-industrial eyesores sit.

Isn’t that just brownfield again, you might ask? No, says Labour, the “category will be distinct to brownfield with a wider definition” (whatever that might be).

You can understand why it has done this – to head off the more vocal NIMBYs (including among its own MPs) who claim the countryside is being concreted over, when only 6.8% of land within the Green Belt is in “developed use” (including agriculture and forestry) and while only 1.3% of all England is given over to housing (2022).

Posh estate agent Knight Frank reckons that there are up to 11,000 such grey belt sites that could provide space for anywhere between 100,000 and 200,00 homes.

It is to be applauded that the party is addressing supply side issues. Most initiatives – e.g. Help to Buy, 99% mortgages – focus on demand by making it easier for people to buy houses.

But our problem is not demand: demand is ample, demand is sky-high even. The sector has potential customers coming out of its ears. Our problem is that nowhere near enough homes are built for those that want them, where they want them and at prices they can afford. This has resulted in all sorts of distortions, from crazy prices and generational inequality to inappropriate configurations (too many flats) and geographical over-concentrations.

The focus on brownfield and grey belt is consistent with Starmer’s claim that he, if he becomes prime minister, is going to ‘back the builders, not the blockers,’ yet he goes and spoils it with golden rules relating to affordable homes and boosting public services and infrastructure.

In the case of the former, “plans must target at least 50% affordable housing delivery when land is released” and, of the latter, “plans must improve public services and local infrastructure, including more school places and new health centres.”

No one conceptually would object to such provisions, but whatever the chat around the Labour table was when framing these plans, plainly the word ‘viability’ wasn’t used.

That fourth rule, for instance, sounds like CIL and Section 106s on steroids.

And no amount of brownfield or grey belt land availability is going to move the needle one bit if putative developments are rendered uneconomic by these golden rules. You’d think the penny would have dropped by now: that housebuilders are in this for a living, and not for fun; so it remains to be seen if it will if, as and when Starmer wins the GE.

Simon shows Labour goes grey with heart for ‘golden rules’ marathon

T

welve months after heart surgery, Castle Green development director Simon Finlay has marked the milestone by running a half marathon in aid of the hospital that saved his life.

Simon underwent major surgery at the Liverpool Heart and Chest Hospital, just days before his 46th birthday yet, despite complications requiring further intervention, returned to work just 13 weeks late.

Simon then decided he’d run the Liverpool Half Marathon in aid of the Liverpool Heart and Chest Hospital on March 17th – his 47th birthday. With the support of Castle Green, family and friends, Simon has raised well over his £1,000 target, with more than £3,700 donated to date.

L

Angela Rayner, Keir Starmer and the Wavensmere Homes construction team at the Nightingale Quarter development in Derby city centre.

abour has announced five ‘golden rules’ for green belt housebuilding, including a commitment to free up “poor quality” ‘grey belt’ parts of the belt, while upping the amount of affordable housing each site should bear to 50%. The term grey belt refers to neglected areas such as poor quality wastelands and disused car parks that are in the green belt.

The rules are designed to defeat suggestions that the green belt is at risk from a potential Labour government as the General Election looms this year or early next.

Labour’s five ‘golden rules’ for the green belt are: “1. Brownfield first: Within the green belt, any brownfield land must be prioritised for development.

2. Grey belt second: “Poor-quality and ugly areas of the green belt should be clearly prioritised over environmentally valuable land in the green belt Poorquality and ugly areas of the Green Belt should be clearly prioritised over naturerich, environmentally valuable land in the green belt. At present, beyond the existing brownfield category the system doesn’t differentiate between them. This category will be distinct to brownfield with a wider definition.

3. Affordable homes: Plans must target at least 50% affordable housing delivery when land is released.

4. Boost public services and infrastructure: Plans must improve public

services and local infrastructure, including more school places and new health centres.

5. Improve genuine green spaces: Labour rules out building on genuine nature spots and requires plans to include improvements to existing green spaces, making them accessible to the public, with new woodland, parks and playing fields. Plans should meet high environmental standards.”

Reaction to the grey belt approach has been mixed. The National Federation of Builders says the policy is “A win for all parties which is why we support it,” while CPRE, formerly known as the Campaign to Protect Rural England, reckons “There are enough ‘shovel-ready’ brownfield sites in the UK for 1.2 million new homes – this is where we should start.

“We must also abandon the existing piecemeal approach and look at the Green Belt as a whole. The Green Belt needs to deliver affordable homes on brownfield sites, while today's scrubland can become the woodlands and wetlands of tomorrow.”

Scrubland was identified as a particular opportunity for development by Lisa Nandy in June 2023.

The golden rules form part of a pledge

by Labour to build 1.5 million homes over the five-year term of the next Parliament should it come to power. This is identical to the 300,000 homes a year target the Conservatives set themselves and have yet to meet.

BNG goes live for small sites

M

andatory Biodiversity Net Gain (BNG) rules went live for small site developers on April 2nd 2024, two months after their initial rollout.

Under amendments to the Town & Country Planning Act 1990 (introduced under Schedule 14 of the Environment Act), the BNG framework mandates a minimum 10% increase in natural habitat quality or quantity for planning permission.

Developers must now submit plans to Local Planning Authorities, showcasing how their projects enhance biodiversity.

Small sites now subject to the BNG rules encompass residential developments with 1-9 dwellings on less than one hectare. Developers must appoint a competent person to conduct a Small Sites Metric assessment, evaluating pre-development habitats and postdevelopment landscape designs.

In line with the biodiversity gain hierarchy, compliance with BNG could involve strategies such as enhancing onsite biodiversity and integrating on-site and off-site efforts with purchasing

biodiversity credits a last measure.

Lucy Dixon, sustainability lead at Veriforce CHAS, comments: “For smaller projects, however, the implications of the policy will be keenly felt. Constraints in resources, finances and the space available to implement biodiversity offsetting measures can all pose a challenge to the viability of small site developments.

“However, BNG also presents opportunities for collaboration, innovation, and creative problem-solving, all of which are becoming increasingly key as the construction industry strives to become more sustainable.”

rchaeologists from the Red River Archaeology Group working on a Barratt and David Wilson Homes housing development in Oxfordshire have uncovered a remarkable Roman villa complex.

The Brookside Meadows site in Grove, Wantage, sits on a landscape inhabited since the Bronze Age and includes a villa complex richly decorated with painted plaster and mosaics, and a monumental hall-like ‘aisled building’ with hints of internal colonnades.

The artefact-rich site was longlived, with Roman activity extending from the 1st or 2nd centuries into the late 4th or perhaps even the early 5th century AD.

DEVELOPMENTS Acorn down on the farm Acorn Property Group has bought the land it needs to build another nine houses next to its existing Cross Farm development in Wedmore, Somerset. In keeping with the wider 31home Cross Farm development, these homes will be designed to complement their village surroundings, but with modern features inside.

The exteriors will feature traditional materials such as stone, timber cladding and dark roof tiles while the interior is fitted with high-performance windows and German kitchens with stone worktops. All the homes will have offroad parking and gardens.

Features to support energy efficiency include enhanced building fabric, air source heat pumps and solar PV panels.

Acorn will be making £182,000 of Section 106 contributions as part of its commitment to Cross Farm, of which £150,000 will be used to support new affordable housing.

E-mail your latest developments to phpd@hamerville.co.uk AJC Group wins New Forest appeal AJC Group has won an appeal against over New Forest District Council, which rejected its plans for 37 homes on Dibden Purlieu on the edge of the New Forest. The Dorset-based firm has received planning permission from the Planning Inspectorate to develop 25 family homes on the same 0.9-hectare (2.2 acre) site on Noads Way. AJC Group revised its plans, with input from stakeholders and planning officers, to meet the needs outlined in the Hythe and Dibden Neighbourhood Plan and contribute towards the NFDC housing land supply targets.

These will be a mixture of two-bedroom, three-bedroom and fourbedroom houses. The homes will feature traditional detailing including red brick porches, tiled roofs, bay windows and exposed barge rafters.

The development will have 56 car parking spaces, with at least two for each property, and secure bike storage. All homes will have private amenity space and the development will include two areas of open space and opportunities for biodiversity net gain.

Stately progress by Bargate Homes Hampshire-based Bargate Homes has secured planning permission from Havant Borough Council for 41 homes in the grounds of Southleigh Park, a former stately home and parkland in Havant.

The development will have three key character areas, with a variety of building types, consisting of Georgian villas and cottage-style homes, alongside the historic core. Resident and visitor parking spaces will be provided in accordance with local policy, with a range of driveways, on-plot garages, car barns, on-street bays and parking courts. The new homes will range in size from one to four-bedrooms, all with EV charging points as standard.

The company had already won planning permission to convert the original Grade IIlisted house, and associated listed buildings, into 20 new homes. The approved final scheme offers 61 homes in total, consisting of 41 new-build homes and 20 conversion homes.

The proposals will see the retention of the majority of the existing trees on-site, alongside significant tree planting, to allow residents and the wider community to enjoy a traditional parkland setting.

Much of the site will comprise publicly accessible open space, including a formal lawn area immediately in front of Southleigh Park House, and informal walking routes beneath the canopies of retained mature trees, particularly those along the site’s boundaries.

Sigma scheme in Barns Green Horsham-based Sigma Homes has secured a 1.9Ha (4.7acre) site in Barns Green, West Sussex, for a £16m development scheme of 32 energy-efficient homes. Dubbed ‘Sumners Fields’, the estate is designed by Worthing-based ECE Architecture and will consist of one-, two-, three- and four- bedroom apartments and houses. Twelve of these properties are allocated for affordable housing, providing an above policy 37.5% allocation.

According to Sigma Homes the development is in line with Natural England’s current advice on water neutrality and will be constructed utilising timber-frame technology and a range of other ‘green’ features including grey water recycling, to enable residents to significantly reduce their water usage, carbon footprint and energy bills.

Surrounding houses in Barns Green range from post-war homes to rural timberclad houses with red brick and white-painted window frames, so Sumners Fields will conventional yet modern in style.

New landscaping, public open space, and ecological enhancements will be provided with most of the existing trees and hedgerows will be retained and enhanced.

There will be sufficient parking available for each new home, as well as cycle storage. EV charging points will be provided to all houses with a garage and driveway, with further charging points allocated to the apartments.

Homebuyer Hub reflects Longbridge heritage Edward Thomas Interiors has delivered a Homebuyer Hub for St. Modwen Homes’ West Works development in Longbridge, Birmingham, that references the site’s importance in automotive history.

The West Works project will transform the former MG Rover factory site into a residential community. The Homebuyer Hub is where prospective buyers will meet sales staff, review house types and plans and will act as both an information centre and workplace.

The site was a base for car manufacturing for more than a century so an industrial aesthetic was chosen.

The Hub features locally sourced artwork and accessories, as well as items depicting classic Rover cars and scenes from the production line.

MARKET REPORT

The latest figures from the Builders Merchant Building Index (BMBI), published in March, reveal that builders’ merchants’ value sales were down -2.1% in January compared to the same month in 2023, with volume sales falling -3.2% and prices creeping up +1.1%. With one more trading day this year, like-for-like sales were down -6.5%.

Tentative start to 2024 as January value sales slip -2.1% year on year

Y

ear-on-Year

Nine of the twelve categories sold more this year than in January 2023 with workwear and safetywear (+18.3%), landscaping (+6.2%) and decorating (+6.1%) the better performers. However, falling sales in two of the largest categories impacted overall sales: heavy building materials (-3.8%) and timber and joinery products (-6.3%).

Month-on-month

Compared to a poor December 2023, total merchant sales in January were +41.2% higher month-on-month. Volume sales were up +44.2% while prices were down -2.1%. With six additional trading days in January, like-for-like sales increased +2.7%. All categories sold more including the largest three categories: landscaping (+52.2%), timber and joinery products (+43.8%), and heavy building materials (+42.5%).

Services (+19.2%) grew the least.

Rolling 12 months

The Builders Merchant Building Index (BMBI) The BMBI is a brand of the BMF. The BMBI report, which is produced and managed by MRA Research, uses GfK’s Builders Merchant Point of Sale Tracking Data which analyses sales out data from 92% of generalist builders’ merchants’ sales across Great Britain. The full report is on www.bmbi.co.uk.

Total merchant sales in the 12 months from February 2023 to January 2024 were -5.2% down on the same period the year before (February 2022 to January 2023). Volume sales were 12.9% lower and prices were up +8.8%.

With two more trading days in the most recent 12-month period, like-for-like sales were -6.0% lower. Eight of the twelve categories sold more, with renewables and water saving (+20.6%) and decorating (+8.1%) the standout categories. Again, the three largest categories – heavy building materials (3.7%), landscaping (-11.0%) and timber and joinery products (-13.9%) – sold less.

Ian Doherty, chief executive of Hexstone and the Owlett-Jaton brand,

and BMBI’s expert for fastener and fixings said: “Subdued market conditions in both new construction and RMI has impacted directly on volumes in fasteners and fixings, with sales continuing to be down year-on-year.

Compared to the previous two years, prices have continued to ease, with lower cost prices from the Far East and, until recently, lower shipping costs. With the majority of products being purchased in USD, the slight strengthening of GBP has also helped to keep prices down. All of these factors have contributed to a decline in the value of sales.

“However, events in the Red Sea may continue to have an impact in 2024.

With the majority of shipping lines having diverted their Far East routings away from the more direct Red Sea and Suez Canal route, to the longer Cape of Good Hope route, there are impacts on cost price and supply. Shipping costs have had surcharges applied to reflect the longer passage and therefore more expensive route. But the longer route also has a marked impact on shipping capacity, and a previously 8-10 week return trip from the Far East to Europe will now take 12-14 weeks. This reduction in capacity, coupled with a growing imbalance in container availability, is resulting in shipping rates moving up which will feed into higher prices for fasteners and fixings.”

HOUSEBUILDERS ON HOUSEBUILDING

Material matters

Joel Winders, commercial director of Kingswood Homes, relates the challenges facing developers when it comes to sourcing materials – and at good prices.

10 May Professional Housebuilder & Property Developer

O

ne of our biggest challenges over the recent years has been procuring materials; firstly, at the right price and, secondly, in timescales that work with our programmes: something which rarely has gone hand in hand.

We have battled with multiple world events that have impacted on the housing industry by way of rising costs and lack of supply. Prices rose like a rocket from 2020 – 2022 and have fallen like a feather in 2023, and while supplies now become readily available, there is a lack of demand. It appears on face value that merchants and suppliers are not passing on the price reductions as fast as their historic price increases which were filtering through daily at the time.

Kingswood Homes is a wellestablished SME but, as is the case with all SMEs, we do not have the same buying power as the large PLCs, which ultimately means we have to fight harder to secure the best rates and periodically review prices to ensure we are receiving best value for money.

Our approach, which we have found rewarding to date, has been to open dialogue with our supply chains to renegotiate existing deals to try and negate re-tendering processes which secures continuity on developments and ongoing relationships with existing supply chains.

The cost efficiencies we are making with the market slow down are being focused on delivering better value for customers through increasing the sales team’s incentive allowances in a bid to increase reservation numbers to

somewhere in between what feels like a period of feast or famine.

Customer expectations have also increased when it comes to closing the deal with expectations of a sales incentive margin of anywhere from 1% to 5% of purchase price. This is something that we review on a plot-by-plot basis.

While there is a lot of doom and gloom in the industry, we have been encouraged with the continued reduction in mortgage rates as the market continues to stabilise and inflation continues to reduce to a palatable level.

This has been very encouraging for our sales outlets and in the early part of 2024 we have seen customer numbers increase significantly, although many potential buyers are still hesitant to commit or put their house on the market, presumably holding off until they feel the market has bottomed out.

A key driver to kickstart the industry again will be the welcomed reduction in the Bank of England base rates which are predicted to reduce by 1% by the end of 2024 which will have a large effect on commercial lending and residential mortgages alike. Without this we could continue to see future sites moth-balled and delayed in a bid to reduce the effects of the downturn with the goal of coming back stronger in the future.

SPECIAL REPORT

Ticking the BNG box While February 2024 saw the rollout of the mandatory Biodiversity Net Gain (BNG) requirements for larger developments, small sites had until April to adapt. Lucy Dixon, head of global new markets at Veriforce CHAS, outlines some key considerations for small site developers aiming for compliance.

T

he Biodiversity Net Gain (BNG) framework, mandated under the Environment Act 2021, officially launched on February 12th, requiring a minimum 10% BNG for planning permission with an extended transition period for small sites ending on April 2nd.

This means developers must submit plans to their Local Planning Authority (LPA) showing how their project will contribute to an overall increase in the quality or quantity of the natural habitat of the site on which they are situated by a minimum of 10% – with some LPAs demanding increases of more than 10%.

For major developers, incorporating BNG into project designs will likely not be entirely new. For smaller projects, however, the implications of the policy might be more keenly felt. Constraints in resources, finances and the space available to implement biodiversity offsetting measures can all pose a challenge to the viability of small site developments.

Purpose of BNG

The fourth State of Nature Report, unveiled in September 2023, highlighted the alarming decline of biodiversity in the UK. The report underscored the UK’S ongoing environmental degradation, which is already acknowledged as one of the most nature-depleted nations globally.

The data revealed a troubling trend, indicating that since 1970, UK species have, on average, experienced a 19% decline, with almost 1 in 6 species (16.1%) now facing the imminent threat of

12 May Professional Housebuilder & Property Developer

extinction. It's clear that urgent action is required, and the BNG framework supports this.

In the context of the BNG framework, small residential development sites are defined those with dwellings numbering between 1-9 on a site measuring less than 1 hectare, or in cases where the number of dwellings is unknown, on a site area less than 0.5 hectares. Certain exemptions exist within the BNG policy, notably for small self-build and custom homebuilding sites.

Appointing a competent person

Developers overseeing small sites must designate a competent person (referred to as the Small Sites Metric (SSM) ‘user’) to carry out a SSM assessment using the SSM tool. A competent person does not have to be an ecologist, but they must have the necessary knowledge and experience in line with BS 8683:2021 Process for designing and implementing biodiversity net gain to perform and review SSM calculations.

SSM users should demonstrate competence in the following areas: identifying pre-development habitats on

012_PHPD_MAY24_Layout 1 22/04/2024 13:20 Page 13

the site; and understanding management requirements for habitats to be created or enhanced in the post-development landscape design.

The SSM can be used on projects that qualify as a minor development and on land where there are no priority habitats present. The list of priority habitats requiring conservation include, for example, ancient hedgerows, traditional orchards and lowland meadows. Larger developments should refer to the Statutory Biodiversity Metric.

How can developers achieve BNG?

Government guidance sets out three ways a developer can achieve 10% BNG: l They can enhance and restore biodiversity on-site (within the red-line boundary of a development site). l If developers can only achieve part of their BNG on-site, they can deliver through a mixture of on-site and offsite. Developers can either make off-site biodiversity gains on their land outside the development site or buy off-site biodiversity units on the market. l If developers cannot achieve on-site or off-site BNG, they must buy statutory

biodiversity credits from the government, with the government using the revenue to invest in habitat creation in England. This must be a last resort.

Developers can combine all three options but must follow the steps in order.

This order of steps is called the biodiversity gain hierarchy.

For small site developers, particularly those with limited land availability, familiarizing themselves with the details of the biodiversity gain hierarchy is key to the success of their projects achieving planning permission.

Incentives for developers

BNG policy offers opportunities for innovation, especially for smaller developers. For example, incorporating green infrastructure or biodiversityfriendly design elements (a wildflower roof) can enhance a project's marketability and value.

Fulfilling BNG requirements can foster collaboration, easing compliance burdens.

Engaging stakeholders like landowners, ecologists, and environmental organisations early in the planning process can address potential issues.

Pooling resources and expertise not only maximise biodiversity enhancement for the current project but also establish a cost-effective blueprint for future developments.

While mandatory BNG poses challenges for small development sites, it also presents opportunities for collaboration, innovation, and creative problem-solving. Recognising the intrinsic value of nature is essential for contributing positively to biodiversity conservation and ensuring its significance for current and future generations.

CONVERSION & RESTORATION

During the renovation of a basement duplex apartment in a prime residential street in Clifton, Berkeley Place made an unusual discovery. PHPD reports.

14 May Professional Housebuilder & Property Developer

Shelter from the storm

I

n WW2, not least due to the presence of the Bristol Harbour and The Bristol Aeroplane Company in Filton, the city of Bristol was a target for bombing. Easily found as enemy aircraft were able to trace a course up the River Avon from Avonmouth, Bristol was the fifth most heavily bombed British city of the war.

Between November 24th 1940 and 11th April 11th 1941, there were six major bombing raids on the city; and like many urban dwellers, the population moved underground to seek safety from the Nazi onslaught.

In Royal York Crescent, the basement of the duplex was converted to a bomb shelter – during which time the occupants recorded a log of the raids they endured on the wall – which became neglected and overlooked after peace was restored.

This forlorn testament to our finest hour lay forgotten until it came to Berkeley Place to renovate the flat on this striking Georgina terrace. The historic shelter was rediscovered and given a new lease of life to make it liveable again.

Overall, the Grade II listed building has had a full refurbishment of the front terrace, living room, hallway, kitchen, utility, dining, bedroom and a master ensuite – with a Crittall-style terrace. The feel of the project is bringing the old into the new and cleverly designing the small space to feel larger. Creating more space in the home was a challenge which was overcome with clever storage.

The whole apartment has a new warmth with new timber and underfloor

heating. To mix old with new, a variety of suppliers were used such as Howdens and Farrow & Ball. The tiling came from Mandarin stone, wallpaper is Harlequin Salon Wallpaper and the steel fenestration was supplied by Fabco.

A Chelford navy customised kitchen was installed along with quartz worktops, classic fusion square patinated brass hot taps from Quooker, parquet flooring and full height wall bookshelf – a feature also in the living room. In the dining room and hallway, new glazed metal framed doors and windows were installed, while the stairs were fitted with a curved timber handrail to the outer wall and cleaned sandstone flooring.

The basement was converted into a snug bedroom and bathroom. To create the snug there was a full renovation; and repairing and repointing of the stone flag flooring. The bedroom was cleverly subdivided to maximise use of space and provides two separate sleeping spaces.

L

ocated close to Bude town centre, with easy access to all facilities, the Grade II landmark building, comprising the church and adjacent Sunday school, overlooks an 18-hole golf course and is a short level stroll from the popular Crooklets beach.

It was built in 1905 in rectangular form with gable ends and a grandiose west front with north and south towers which were constructed in stone from a Bude quarry.

Pitch pine, allegedly washed up from a local shipwreck, was used in the construction of the pulpit, organ frame and pews.

The approved sympathetic planning consents – Cornwall Council App PA21/10056 and listed building consent App PA21/08578 – propose retention of the pulpit and organ structures in the design of one of the internal communal staircases.

There has been historic movement to the North Tower, yet advice received is that it is stable, but must be subject to the successful bidder's investigation.

The push for decarbonisation is something that has been acutely felt in the builtenvironment industry, particularly when it comes to the adoption of electric vehicles and the Government’s introduction of Part S. James Jarvis, business development manager at Rolec Services, reports.

Charging forward A s the UK prepares for a Net Zero future, and Part S of the Building Regulations weighs in on housing and electric vehicles (EVs), housebuilders are grappling with the various practical issues around providing charging for residents of all new homes.

Electric vehicles (EVs) are becoming more affordable and practical, and the UK Government has set ambitious targets to phase out the sale of new petrol and diesel cars by 2030. Along with the recognised standard features of a charge point (a minimum output of 7 kW and a universal power socket), the Government also introduced the Electric Vehicles (Smart Charge Points) Regulations.

As the demand for EV charging infrastructure increases, it is essential that installation is made as simple and easy as possible. In the past, installing EV charging points was a complex and timeconsuming process, requiring significant planning and co-ordination.

Convenience is the key. By incorporating Protective Multiple Earth (PME) fault detection technology, the installation process can be streamlined, the risk of faults can be reduced, and overall reliability can be improved. In-built PME fault detection has been invaluable in achieving this, since it means the unit won’t need an earth rod to be installed, which means less hassle for the installer and less disruption to the customer.

Scheduled charging is one of the key things to look out for: introduced to reduce strain on the grid by encouraging users to charge during off-peak hours.

Compliant units manage this via an online app, which also gives the user full control of their charger. Furthermore, EV charge points now must have upgraded security measures, such as built-in tamper alerts.

Another consideration is the use of smart charging technology, which allows for remote monitoring and control of the charge point. This technology can be integrated with other smart devices for reception of live updates and alerts.

Load balancing and management

Adding charge points to a development means that the demands on the electrical load can increase significantly. Therefore, influencing the capacity needed on site.

Load balancing solutions can increase the number of operable charge points on the site’s existing available supply.

For single charging units, automatic dynamic load balancing via a CT clamp that is attached around the property’s live cable between the meter and consumer unit. The device uses the current to determine how many amps are flowing in the cable.

Smart Charging units also allow for dynamic load balancing, monitoring the property’s overall electrical usage and adjusting the power to the EV charger accordingly, protecting the property’s main fuse. Increased use of modular units that can be easily installed and expanded is as demand for charging infrastructure grows.

Keep the weather with you The low-carbon heating challenge: should builders and developers focus on smarter controls? Will Heinzelmann, product director at Passiv UK, attempts to answer the question.

18 May Professional Housebuilder & Property Developer

T

he UK will have to decarbonise domestic heating to meet its 2050 Net Zero targets. Since those targets were first enshrined in law, heating has been the elephant in the room of the ‘big three’ areas for decarbonisation - power, transport, and heating. The transition to low-carbon power has been rapid, with emissions from electricity generation falling by more than 60% since 1990. Transport is also well on its way, with the millionth electric vehicle having been registered in January.

Decarbonisation of heating, however, has been sluggish at best.

After reviewing various options for lowcarbon heat, it looks like the Government is set on heat pumps as the main solution, whether installed individually outside homes or as part of larger, centralised heat networks. That’s a good thing and the right decision but decarbonisation with heat pumps depends on two things: they have to run efficiently, and they need to consume low-carbon electricity.

An efficient heat pump is one with a good Coefficient of Performance (CoP). Heat pumps are typically very efficient. A new gas boiler will have an efficiency of 85% if it’s set up correctly but a heat pump can have an efficiency of well over 300%. No, that’s not breaking the laws of physics – as that’s

because a heat pump extracts ‘free’ energy from an external source, usually from the air or ground outside the home.

The efficiency of a heat pump is determined by the flow temperature, which is the temperature of the water that flows from the heat pump into the radiators within a home. A lower flow temperature means a higher CoP and it’s the heat pump or its controls that determines this flow temperature.

A third of heat pumps are still installed and commissioned to operate at a fixed flow temperature. That’s easy for an installer, but a disaster for a heat pump’s efficiency. The other two-thirds use a weather compensation curve, which are the settings the installer puts in the heat pump that tell it what flow temperature to produce for a given outdoor temperature.

The idea is that the colder it is outside, the hotter a home’s radiators need to be to keep it warm.

This is great for the efficiency of a heat pump if the installer gets the settings exactly right, which they won’t because it's an impossible thing to do. They calculate the weather compensation curve at the point of installation using the best information that they have. Probably a heat loss calculation they have produced for the home.

018_PHPD_MAY24_Layout 1 22/04/2024 13:29 Page 19

But that weather compensation curve doesn’t change if they get it wrong and it doesn’t adjust to new information. Nor can it look at weather forecasts or factor in how the homeowner uses their heating system. So, it's better than using a fixed flow temperature, but we can do better.

That’s where smart controls come in.

The latest generation of smart controls have been designed to work with a heat pump and can remove the need for an installer to set a weather compensation curve. Instead, from the moment they are installed, they learn how a home heats up and cools down and how the heating system behaves.

Then, they use local weather forecasts to calculate the optimal way to meet a homeowner’s comfort requirements, continuously optimising the heat pump’s flow temperature to maximise its CoP. The outcome is a dynamic weather compensation curve, and one that is always, exactly right.

Alongside efficient operation, heat pumps depend on a low-carbon electricity source for effective decarbonisation. Our electricity grid will continue to decarbonise, but as we become increasingly reliant on renewable sources of energy, the carbon intensity of the electricity we consume will vary massively throughout the day.

There will be times when it is very windy or sunny and the grid will be very green. But there will also be times when it is very still, cold, and dark and homeowners want to heat their houses or charge their electric vehicles at the same time. It is likely that this demand will still be met by a significant proportion of fossil fuel generation and that means that while across the year our power may be greener, it may not be when a homeowner needs to turn on their heat pump!

Here again, smart controls have a role to play. In the last few years, there has been great innovation in electricity tariffs that has seen ‘time of use tariffs’

incentivising us to use electricity at different times of the day. These types of tariffs have rates that vary every single half-hour and are only announced 24 hours in advance.

Typically, high prices correlate with high carbon emissions, so rates are higher at peak times in the evening, when the grid is at its dirtiest. In theory, homeowners could manually control their heat pump to take advantage of these price swings. But then they wouldn't leave the house much.

Instead, smarter controls can automatically adjust a home’s heat pump according to the rates offered by a timeof-use tariff. Some of these controls can adjust a heat pump’s operation to maximise the consumption of cheap, lowcarbon electricity by preheating a home and storing warmth in the fabric of the building. At peak times, the heat pump then doesn’t have to work as hard, saving money and the planet.

It’s good that the Government seems to have recognised the need to tackle the elephant in the room, but maybe they’ve picked the wrong elephant. Most of the heat pumps you can buy seem similar.

Perhaps it's the controls that can make the big difference.

SUSTAINABILITY & ENERGY EFFICIENCY

The recovery position As we edge nearer to the 2050 Net Zero deadline, Mechanical Ventilation with Heat Recovery (MVHR) is poised to become an integral component of modern energy-efficient new build homes. Steve Pearce, product manager at Vent-Axia, explains what this means.

N

ow is the time for to prepare.

The UK has a legally-binding target to meet Net Zero by 2050. To lay the ground work for moving towards this target the Government published the most recent amendments to Part L (Conservation of Fuel & Power) and Part F (Means of Ventilation) of the Building Regulations, with Part L requiring a reduction of almost a third less carbon for new homes.

One result has been a significant trend towards developers specifying a combination of centralised Mechanical Extract Ventilation (MEV) with decentralised Mechanical Extract Ventilation (dMEV). However, MEV is very much an interim stage on the journey as we move towards Net Zero and more advanced ventilation systems.

The next step will be the introduction of the Future Homes Standard in 2025, which is currently under consultation. This aims to ensure that new homes will produce 75-80% less carbon emissions than homes built under the current Building Regulations.

To meet the Government’s 2050 Net Zero target, buildings need to decarbonise which involves the widescale electrification of heating, moving away from fossil fuels, as well as significant improvements to air tightness and building insulation. In fact, airtightness looks set to be a critical feature of energy-efficient homes going

forward with new homes adopting the Fabric Energy Efficiency Standard to measure energy efficiency.

However, an airtight building envelope should allow controlled air exchange and air permeability to give suitable ventilation, yet still prevent condensation and heat loss. To meet these requirements the ideal solution is energy efficient Mechanical Ventilation with Heat Recovery (MVHR) since it provides healthy filtered air while recovering heat that would be otherwise lost. But with a wide variety of units on the market what elements should housebuilders consider when specifying?

Energy efficiency

A major factor when choosing an MVHR unit is ensuring it will help a development meets its Dwelling Emission Rate (DER). To reduce carbon emissions, housebuilders should specify MVHR units with industryleading low specific fan powers (SFPs) and heat recovery as high as 93%.

However, when selecting an MVHR unit, efficiency cannot be at the cost of sound levels, since a noisy system will result in disgruntled homebuyers and call backs. Aim for units offering near silent operation with sound levels as low as 15.5 dB(A) and check sound levels are independently tested.

Installed performance

Although specifying a heat recovery unit which boasts low energy usage

Professional Housebuilder & Property Developer May

021_PHPD_MAY24_Layout 1 22/04/2024 13:47 Page 22

SUSTAINABILITY & ENERGY EFFICIENCY

and high thermal efficiency is key to meeting a DER, optimum installed performance is also vital. The first step to achieve this is to ensure the ventilation system is designed and installed correctly by a competent ventilation installer. The next step is to make certain the MVHR is commissioned accurately and meets Part F of the Building Regulations. To make installation and commissioning simple the latest heat recovery units therefore feature advanced control systems that provide on board, in-room and app-based control, where full functionality commissioning and monitoring is provided as standard, helping ensure a unit operates to its design intent.

Overheating

As temperatures rise due to climate change, and buildings become more airtight and thermally efficient, the issue of overheating is becoming a concern in new build homes. This problem is expected to worsen over time.

Research by the Resolution Foundation revealed that over a third of homes in England are at risk of overheating in the future as climate change brings hotter summer temperatures. Good thermal comfort is essential in our homes, this means housebuilders need to prioritise summer bypass when

22 May Professional Housebuilder & Property Developer

specifying MVHR. An integral automatic summer bypass can provide free cooling when available and eliminate performance loss.

Indoor air quality

The pandemic brought IAQ into sharp focus making a well-ventilated home an attractive selling point for homebuyers. The latest MVHR systems therefore offer market-leading connectivity which puts homeowners in charge of their ventilation through wireless control platforms that deliver complete control of the home environment, provided through a full range of wired/wireless sensors and a smartphone app. This allows households to make adjustments to a multitude of functions, via a smart-phone app, including increasing ventilation during hot summer periods or reducing speed to minimise running costs while away.

However, to help maintain good IAQ the latest systems also feature control logic that ensures they operate optimally with automated functions, such as built-in intelligent humidistat, frost protection and summer bypass. This function both improves comfort and also prevents issues such as condensation and mould.

Filters also play a crucial role in ensuring good IAQ, housebuilders should therefore install MVHR units so that it is easy to access filters for maintenance. Opting for ISO ePM 10 (M5) and ePM2.5 (F7) filtration options will improve and maintain good IAQ, removing allergens and particulates, creating healthier environments. Not only do filters improve IAQ in a home they also help maintain energy efficiency, reduce heating and cooling costs, enhancing system longevity.

With the Government’s 2050 Net Zero target on the horizon new build homes are poised for substantial carbon reductions and increased air tightness and energy efficiency. This will drive housebuilders towards more advanced ventilation systems and so make MVHR the ventilation of choice.

An intriguing new report from the Hot Water Association suggests that hot water cylinders to be used as thermal stores for grid electricity to build resilience in peak periods. Kevin Lowe, technical manager at the HWA, explains.

24 May Professional Housebuilder & Property Developer

Security in store A

s energy security continues to be a cause for concern for the UK, an industry report (Connected Homes) has identified the potential role of hot water cylinders in balancing demand on the electrical grid.

As difficult a challenge as it may seem, if the nine million cylinders in UK homes were connected through smart controls and used as batteries, the National Grid could unlock 23GWh of energy storage – around half the energy used per day in the UK. Due to the introduction of technologies, like heat pumps, which require hot water cylinders, this number could increase by 36%, increasing the energy capacity to 40GWh. To make use of this energy storage potential, cylinders would need smart functionalities introduced either via retrofitting smart controls or brand-new smart cylinders will need to be installed with gas boilers or heat pumps.

Hot water cylinders’ potential role in the energy mix is substantial and there is work to be done to make the most of this opportunity. The report also highlights the need for policy direction to incentivise the rollout of connected thermal storage in UK homes.

This is particularly needed to prevent people from changing their hot water system to remove the cylinder completely so the number of cylinders in the UK can increase to build capacity.

In addition to incentives to drive more people to install smart cylinders and retrofit controls to existing cylinders, the report lays out the next steps for

improving uptake. This includes making smart controls and cylinders more beneficial to SAP and EPC ratings in new builds and reducing taxes and levies on off peak electricity to bring more value out of storing energy in a cylinder.

The key to making this project a reality will be getting housebuilders and home owners onside, so policy direction must incentivise adopting smart hot water storage.

Whether installing a cylinder with a new heat pump installation, or fitting controls to an existing one, financial support may be required to make it worthwhile.

If we are to get the up to 40GWh of energy storage that our research predicts could be achievable in the UK, developers, Government and heating engineers must work together to help the wider community understand these benefits.

BREEDON On the tiles

Breedon has developed the Generon, a solar panel incorporated into a roof tile so that resembles a conventional concrete tile.

The Generon comprises a 3.2mm monocrystalline tempered glass PV cell discreetly integrated with a Breedon Elite 330mm x 420mm base concrete roof tile that is laid in sequence with matching standard roof tiles.

Interconnecting cables then link the Generon tiles to create an overall solar output based on the number of tiles fitted. Typically, 260 tiles are required to generate a 4kW PV system – the benchmark for family homes.

Fitted by roofing contractors using storm clips in sequence with the standard concrete roof tiles, the Generon system then simply connects to the remaining PV infrastructure to generate safe, reliable and renewable energy.

This combination delivers a seamlessly integrated solar roof, without compromising aesthetics. Solar roof tiles typically have longer lifespans than traditional solar panels and need less maintenance over time, owing to the securely integrated nature of their design.

MHIAE Hush hush heating

Designed to deliver heating, cooling, and hot water, the Hydrolution EZY heat pump from MHIAE is available in two models,10kW and 14kW, providing a low-carbon, easy-to-install alternative to fossil fuel boilers.

The A2W heat pump range also has anti-vibration technology to reduce sound power levels so that the 10kW class model only emits noise to 60dB (A) even when running at full capacity. There is also a quiet mode that reduces operational noise and ensures compliance with various noise regulations.

To simplify installation the Hydrolution EZY series features an integrated water heat exchanger in the outdoor unit, eliminating the need for refrigerant piping, and employs R32 refrigerant to significantly boost efficiency.

Hydrolution EZY units also work effectively in a wide range of outside temperatures, from -25˚C to 43˚C, and can deliver 60˚C hot water even when the outside temperature is -25˚C, making them a great replacement for combustion-type boilers in cold regions and reducing carbon emissions significantly.

Dan Leaney, Xwatch safety solutions operations director, talks about the latest in subterranean technologies which are changing the way we approach infrastructure and domestic housing projects.

A

Tales from the underground

pril 2023 saw the Geospatial Commission launch a groundbreaking underground digital map to bolster economic growth, enhance safety, and curtail delays. The United Kingdom is home to approximately four million kilometres of subterranean pipes and cables.

Every seven seconds, a hole is excavated to install, repair, maintain, or refurbish these vital assets that ensure the continuous flow of water, gas, electricity, and the connectivity of telecommunications lines.

It’s estimated that roughly one in every sixty-five excavations results in an accidental strike of these assets, leading to approximately 60,000 such incidents annually. These strikes have significant repercussions, including around £2.4 billion in economic costs, endangering workers’ lives, and causing disruptions in everyday life.

The National Underground Asset Register (NUAR), a government-led initiative, aims to rectify this by establishing a singular, comprehensive platform for sharing data on the location and condition of underground assets. The primary objective of NUAR is to streamline the data-sharing process, mitigate the risk of hazardous utility asset strikes, and promote a more efficient management and maintenance of these assets.

Of course, this data needs to be of practical use and exists in parallel with the integration of technologies like 3D

mapping into site surveys. This sophisticated approach enables more precise and comprehensive site analysis, ensuring higher levels of safety and efficiency. This evolution highlights the remarkable progress in construction site surveying methods, marking a transition from basic manual strategies to cuttingedge technological solutions.

The transition from traditional manual surveying methods to advanced technologies like 3D mapping, mobile LiDAR, and drone-based surveying has significantly improved accuracy, safety, and efficiency in construction site surveying.

These technologies enable better project planning, risk assessment, and decision-making, positioning them as indispensable tools in the modern construction industry and are now augmented by 3D avoidance systems.

These systems use cutting-edge software to create '3D avoidance zones', which can spot potential dangers both above and below the surface. By giving a clearer picture of the entire worksite, these zones significantly reduce the risk of accidents, making them a key part of modern construction safety.

This sophisticated system employs software to create and import 3D zones, effectively identifying hazards both above and below ground. Its significant impact lies in elevating operator safety, offering a detailed perspective of the worksite and thus diminishing the likelihood of accidents.

GROUNDWORKS & PLANT

This technology has transformed traditional safety measures, providing a more comprehensive approach to hazard detection and prevention.

This comprehensive underground mapping is invaluable. By integrating this detailed subterranean data, such a system can offer a clear and precise picture of the underground landscape, crucial for effective planning and execution in construction and landscaping projects.

The emergence of autonomous excavation technologies marks a substantial stride towards the future of construction machinery. By enabling remote-controlled or autonomous operation, these technologies substantially reduce the need for human presence in potentially hazardous areas, thereby markedly enhancing on-site safety.

When approaching an avoidance zone, the system will take control of the machine’s height, depth and slew movements triggering the hydraulic functions of the excavator to stop once

approaching these zones. The hydraulic control is proportional, meaning the machine’s movement will slow down before completely stopping when approaching an avoidance zone. The motion of the excavator’s tracks can also be disabled so it cannot breach environmental areas or designated no-go zones, even avoid overheard power cables or gantries.

The implementation of the 3D avoidance zone systems brings a plethora of benefits. It significantly improves the safety of machine operators and surrounding workers, thereby minimising the likelihood of accidents. Operational efficiency is enhanced, leading to reductions in downtime and unforeseen costs, which positively affects project timelines and budget management.

Additionally, this system simplifies the management of incidents involving external infrastructures, reducing administrative burdens and enhancing stakeholder relations.

As part of its long-term plan for housing, the Government is consulting on proposals to strengthen planning policy for brownfield developments.

When developing brownfield sites, care needs to be taken to protect water supplies from contamination.

Caroline Ayres, director, BPF Pipes Group, reports.

Thirst for knowledge

P

olyethylene pipes with an aluminium barrier are routinely used in brownfield applications where potable water needs protecting from possible contaminants in the ground.

They are useful in larger developments as their longer lengths minimise the number of joints needed, saving installation time and the risk of contamination.

BS 8588: 2017 is the industry standard for polyethylene piping systems with an aluminium layer. It confirms through testing, that a pipe and fitting in combination successfully act as a barrier to organic contaminants, ensuring that concentrations remain below a threshold to protect drinking water quality. Fittings for connection of PE barrier pipes shall comply with WIS 4-32-11: 2018 up to 63mm diameter or BS 8561: 2021 for large sizes.

Both pipe and fitting need to be mechanically sound and together be capable of delivering a leak-tight system over the product lifetime. So, to fully comply with BS 8588, manufacturers need to declare the combinations of pipes, fittings and fusion joints which have been proven to meet this standard.

The true benefit of installing these barrier systems is peace of mind for water suppliers and consumers when it comes to the quality of water at the tap. Integrity of the barrier to contamination is assessed through the test for resistance to permeation which is designed to demonstrate that components in a system can together adequately resist the ingress of hydrocarbon contaminants.

The BPF Pipes Group recommends using fittings which have been fully assessed and certified by a third party, such as the BSI Kitemark, to WIS 4-32-11 or BS 8561. Where certification is not available, developers, specifiers and engineers are advised to check that all tests included in the specification have been completed. It also strongly encourages those specifying these types of pipes and fittings to check that permeation testing under BS 8588 has been carried out to the actual pipe and fitting combination being offered, and to check that mechanical performance has been fully assessed to WIS 4-32-11 or BS 8561 using the fittings and barrier pipe for which they are being offered.

Purchasing from a member of the BPF Pipes Group will ensure that confidence in the whole system can be assured as they offer complete pipe and fitting solutions which are tested and awarded a BSI Kitemark. In addition, the products offered by members comply with Water Regulations, the purpose of which is to ensure that public health is protected by preventing any contamination of public water supplies.

The BPF Pipes Group has published guidance on laying the appropriate types of pipes and fittings in such ground and emphasises the importance of specifying and installing such products correctly.

Tim Burnhope, group director, special products at JCB considers housebuilding’s role in the road to zero emissions and explains how hydrogen is the fuel to take us there.

It’s a gas, gas, gas

A

s global leaders left the COP28 conference in Dubai last year, it was hailed as the beginning of the end for fossil fuels. As we plot a course through the climate crisis, it feels inevitable that legislation will soon dictate the eradication of diesel, with construction equipment manufacturers needing to mirror their automotive counterparts in preparing for a future without the fuel which has powered the sector’s machinery for decades.

Electric dreams

However, while battery electric machines will undoubtedly play a part in the housebuilding sector’s road to Net Zero, it will simply not be possible to build the volume of houses we need to build with electric equipment alone. While it is a fantastic solution for compact machines in certain applications – in noise sensitive, underground and highly populated environments – it is simply not a practical or viable route for the larger equipment performing more demanding tasks on site.

While battery electric is suitable for smaller machines which do fewer hours and typically use less fuel, larger machines have a higher energy requirement. In order to power heavy machinery, the batteries would need to be enormous and would therefore prove extremely heavy in situ as well as expensive.

30 May Professional Housebuilder & Property Developer

There would also be issues when it came to recharging, as the machines often operate well away from existing infrastructure, where there is no supply of electricity. Even if there were access to electricity, it would be impractical and unsafe to run electricity cables across the building site to charge the machines.

Daily shifts in earthmoving, drainage and groundworks are typically long and relentless – likely requiring multiple charges in a working day, resulting in machine downtime, hampering productivity on-site.

A viable alternative

In the search for a mobile fuel which can be taken to the machine, ensuring maximum uptime and fast refuelling, HVO, biogas, E-fuels, ammonia, and hydrogen have all come under the microscope. Yet as the majority of these alternative fuels require the production of hydrogen to make them, it makes perfect sense to use hydrogen in the first instance because it is a clean zero carbon fuel which can be produced from renewable energy.

JCB initially investigated hydrogen’s use in fuel cells and in July 2020 unveiled the first hydrogen-powered excavator: a 20-tonne 220X. However, the conclusion we have come to is that, for the time being, the fuel cells are too expensive, too complicated and not robust enough

030_PHPD_MAY24_Layout 1 23/04/2024 13:02 Page 31

for the rigours of the construction site.

Hydrogen engines solve these problems.

They work on the internal combustion principle and will feel familiar to anyone who is used to diesel or petrol engines. The wider benefits are countless. Critically, the cost is roughly the same as traditional engines running on fossil fuels. Unlike batteries, they are not inflationary. And the main benefit, of course, is that these engines burn a carbon-free fuel — hydrogen.

One of the biggest challenges for equipment manufacturers is that despite the importance of a zero emissions alternative, we know full well that construction firms would simply not tolerate an inferior product or one which is significantly more expensive, irrespective of its environmental benefits.

Crucially, the unique combustion properties of hydrogen enable the hydrogen engine to deliver the same power, the same torque, and the same efficiency but in a zero-carbon way. Hydrogen combustion engines also offer other significant benefits.

Hydrogen addresses one of the major challenges with using batteries on larger machines; it allows for fast refuelling and is a mobile fuel solution, allowing fuel to be taken to the machine.

Indeed, recognising from the outset that any hydrogen powered machine needed a complimentary and effective refuelling solution, a mobile refuelling bowser with enough hydrogen gas to fill 16 hydrogen backhoe loaders, and one that can be transported on a trailer if required, has now been designed and built.

Collective responsibility

Our belief is that hydrogen power is a genuinely viable alternative to diesel and battery-powered machinery within the construction sector that can revolutionise the environmental performance of the housebuilding industry without disrupting its essential productivity.

Now that the technology is here, the next step is to encourage governments, authorities, policy makers and major developers to fully embrace it in the fight against climate change – ensuring that the sight of zero emissions hydrogen powered equipment operating on UK construction sites becomes an imminent reality.

WEST FRASER Wet weather flooring

CaberDek flooring from West Fraser flooring enables construction work to proceed regardless of weather conditions. Constructed from moistureresistant particleboard, the CaberDek planks have a non-slip film on the top surface for safety and protection.

Upper floors in new constructions are often installed before the roofing, leaving the floors exposed to weather conditions like rain and frost. CaberDek's protective film safeguards the floor from these elements and offers a non-slip surface for workers.

It also keeps its BBA certification for up to 42 days when exposed, if installed using West Fraser’s CaberFix adhesives.

Even after the structure is sealed from weather, the film keeps the floor safe from damage during interior work like plastering and painting. The film is then removed to reveal an undamaged floor surface.

The product is available in panels of 2400mm by 600mm, in thicknesses of 18mm and 22mm, and can be installed on various joist types using nails, screws, or adhesives from West Fraser.

CaberFix D3 adhesive is designed for strong bonding along the panel joints, while CaberFix Joint&Joist adhesive provides a flexible, high-strength bond to joists, enhancing the floor's resistance to squeaks and contributing to noise reduction, meeting Part E of the Building Regulations for noise passage.

For sealing joints and ensuring durability, especially under freezing conditions, CaberFix Tape and the specifically formulated CaberFix X-Treme tape are recommended to prevent moisture damage to the adhesive joints.

GENERAL BUILDING

WEST FRASER Too snug to creak Creaky floors are banished when using West Fraser’s CaberFloor P5 because this high-performance particleboard has precision-engineered edges that not only ensure that it can be installed quickly but that its joints are too snug to move.

Ideal for humid environments, in both new-build or retrofit applications, the high-density panels come in thicknesses of 18 or 22mm and can be squareedged or tongue and grooved on all four sides to offer maximum flexibility.

Choosing T&G CaberFloor P5 removes the need for intermediate noggins, while ‘secret’ or hidden nailing or screws can be employed within the joints.

Alternatively, CaberFix Joint & Joist adhesive can be applied to the edges, which will also reduce any risk of the squeaks and creaks that blight traditional floorboards and many ply or particleboard decks. CaberFix D4 is also ideal for bonding flooring boards to both joists and tongue and groove joints and for sealing the board edges.

Available in lengths of 2400mm and 600mm wide, the floor panels are both FSC (C012533) and CE-certified.

HADDONSTONE Bollards of stone

Developed to edge residential lawns, paths and driveways, Ball Bollard and Classic Bollard lighting products are both manufactured in Haddonstone’s TecLite material – a durable reinforced, reconstituted stone that closely resembles natural stone in appearance.

Based on the manufacturer’s traditional cast stone balls, the Ball Bollard can be specified with either a hard-wired 240-volt or 12-volt power supply. The light fitting itself is fully waterproof and manufactured in a choice of Marine Grade 316 stainless steel or in solid brass, while the low-energy LED lamp is offered in a warm white. With a diameter of 330mm or 13”, the Ball Bollard weighs 36kg, making it sturdy enough to withstand strong winds and pedestrian contact.

Solar powered, the Classic Bollard features an aluminium and polycarbonate light fitting and is available in silver or black, with warm white ES/E27 LED lamps, and with panels made from high quality monocrystalline. The Classic Bollard, including the light fitting, is 960mm tall and 210mm wide and weighs 22kg.

Designed to function reliably in wet climates and on the longest nights, the efficient long-life lithium-ion batteries charge and manage their energy via a built-in dimming sequence from dusk, ranging from 100% down to 30%, effectively helping to reduce energy usage.

ACO WATER MANAGEMENT Clearing up SuDS

ACO Water Management is aiding housebuilders and developers in adapting to upcoming legal requirements by launching its guide on sustainable drainage systems (SuDS).

Titled Implementing SuDS: Practical advice, key information and preparing developments for Schedule 3, this guide offers free-to-download support to understand the implications of the Flood and Water Management Act 2010's Schedule 3 changes.

These changes will mandate SuDS integration into most new schemes in England, expected to take effect later this year.

The guide addresses common questions and discusses SuDS implementation methods, applications in various developments, and different techniques, including nature-based solutions and engineered systems for biodiversity net gain.

LAST WORD

The inside view: interior design as a marketing aide

I

There’s no denying a professionally designed show home is a housebuilder’s primary marketing tool but when a development really needs to stand out, how else can developers use interior design more creatively?

Steve Hird, director at Edward Thomas Interiors, highlights three recent case studies of unorthodox thinking.

’ve written previously about where housebuilders can take cues from retail so an interesting brief, we fulfilled recently was for a high street retail store. Our client, a retirement living developer, had several developments in close proximity so to attract purchasers from a wider catchment, set up a retail store as a ‘hub’.

The location for this was a quintessential market town so our brief was to make the store as much of a destination as the town itself. A country chic design was installed, using furniture, wallcoverings and accessories that were representative of the client’s brand. The idea being it would be familiar but not corporate. House hunters could take time learning about the different developments and gain a sense of the lifestyle before selecting one to visit and view more closely.

Virtual show homes

Pre-marketing plays an essential role ahead of the launch of any development. But what information can you provide over and above a basic floor plan and site layout?

When a client was releasing homes for sale 12 months ahead of build, they needed more marketing collateral to support early sales. We were commissioned to produce a series of virtual showhomes, devising three deliberately contrasting designs to help house hunters understand the range of

homes available and how the space within them could be used.

Not only were these CGIs given to all those who pre-registered their interest but they were also used to attract overseas purchasers and investors. We then later designed three physical showhomes, meaning interested house hunters could take inspiration from six different concepts, which greatly increased the sales rate.

Design for digital

As VR technology, video walkthroughs and interactive screens become more commonplace in the house buying journey, space needs to be accommodated for these. In sales centres, it’s advisable to plan these from the outset rather than adding later, as they require dedicated space and room to move.

For interactive screens, a zoned space within the sales office works well as it allows house hunters to view while they wait but also means a sales advisor can be nearby to present or demonstrate if required. Where developers offer site tours through VR, we’ve created separate cinema-style rooms to ensure these can take place privately and not distract from the main selling areas.
