NARRATIVE

Punishment noun

the infliction or imposition of a penalty as retribution for an offence.

Historically, punishment was a public spectacle, through methods such as stocks, hangings and public execution. Incarceration was only a prelude to the actual physical punishment, where the body was tortured. Over time, punishment developed to become emotionally torturous, housing prisoners in larger institutions and forcing them to carry out pointless labour, such as working the treadwheel.

The shift of punishment from the body to the soul, created new possibilities for torture. Whereas devices such as the guillotine were intentionally disconnected and emotionless, punishment became more personal. The prisoner’s internal torment of being detained in a cell up to 23 hours per day and loss of freedom became the main source of torturous regime.1

Incarceration noun

the state of being confined in prison; imprisonment.

Now, punishment, and subsequent incarceration, is hidden away from public view. Prisons are often located at a considerable distance from settlements due to the negative prejudice associated with them, but this leads to isolation and exaggerates the unspoken issue of the prison. Approach to incarceration is changing, with historic models like the Panopticon now rejected due to the “unnecessary psychological imposition on the prisoner�. 2 The prison system in the UK is undergoing a crisis, with 62% of prison establishments being overcrowded. 3 Scotland, England and Wales have the highest rates of imprisonment in Western Europe 4 and a large number of these are young people. 6% of the prison population in England and Wales is under 21. 5

Young Offender noun

a person aged under 21 convicted or cautioned for a criminal offence.

In England and Wales, the criminal age of responsibility is 10 years old. Offenders under 18 are known as juvenile offenders and those aged 18-20 classed as young offenders. At 21 and above, a person is classed as an adult offender.

The most common offences for youths are: violence against the person; drug offences and robbery. 6 Many of these crimes are committed for material gain - they are desperate. As a result, their sentences are relatively short, with the average between 6-12 months. Young, vulnerable people are more susceptible to certain risk factors, such as low income, broken families, poor school attainment, impulsive and erratic behaviour.

Young Offender Institutions (YOIs) hold male young offenders from the ages of 18-20 – although in some instances they hold boys aged 15-17, due to risk and capacity. These facilities are often subject to criticism, as their large capacity is a breeding ground for bullying, mental health issues and inmates being negatively impressionable on each other.

Reoffending verb

the act of a person who has committed a criminal offence going on to commit another.

Young people often get caught in cycles of reoffending, with their first offence the beginning of a long career of crime. Those who commit crime from an early age are much more likely to become habitual offenders.

In 2016, 40.9% of juvenile offenders reoffended, in comparison with only 28.6% of adult offenders. 8 Reoffending is estimated to cost ÂŁ10 billion per annum. 9

Bristol noun

an industrial city on the River Avon, in the South West of England.

In June 2019, the Urgent Notification process was invoked on HMP Bristol, meaning it was placed in special measures. HMP Bristol is a male Category B prison and serves the local Bristol community.

It is a local prison (where inmates are detained before a trial or directly after a conviction) and resettlement prison (where, close to their release, inmates are moved to prisons near to their home).

The prison was built in 1883 and is generally rundown, with 40% of cells overcrowded, where two people share a cell designed for one. HMP Bristol does not have any dedicated provisions or facilities to properly accommodate young people and only 25% of prisoners attend any ‘purposeful activity’. 10 Arguably, it is not a suitable environment for young people, especially those of a lower risk and convicted of less serious offences.

Scale noun

the size or amount, used to measure or compare the level of something.

Studies have shown that the closer the prison is to the prisoner’s home, the more successful rehabilitation and resettlement is. 11 There is a clear lack of dedicated Young Offender Institutions in the Wales and the South West of England, and subsequently a lack of these opportunities. There are some facilities combined with adult establishments but many of these are overcrowded. As a result of this lack of capacity, many under 21s are now in adult facilities.

Even though it is not designed to do so, HMP Bristol houses 7% young offenders, with a total prison population of 460 12 - this approximates to 30 young offenders. Dividing prisoners into smaller groups of 25-50, is regarded as the most appropriate size as it is “the smallest group which is yet large enough not to be dominated by one man”. 13

Rehabilitation noun

the action of restoring something that has been damaged to its former condition.

proximity to community commute between spaces small ‘family unit’ inmate day release

Young offenders are often ‘let down by the system’, but if given a second chance and new opportunities there is strong evidence to suggest they can change. Recent studies have shown that the peak age for offending is 17 to 21 years old but the brain is not fully developed until 25 years old. Evidence also suggests that “most young offenders have learned to desist from crime by the age of 32”. 14 The brief is for a YOI in the centre of Bristol, focusing on rehabilitation rather than punishment. The prison will be an open, Category C/D prison, supporting ROTL (Release of Temporary License), where prisoners work in the local community during the day, preparing them to reintegrate into society.

Category A - High risk, closed prison Highly dangerous to the public, aim to make escape impossible.

Client and Stakeholders

The proposed Bristol YOI will be commissioned by Her Majesty’s Prison Service as a new public sector prison. In 2015, the government promised £1.3 billion to create 10,000 new prison places by 2020. 15 So far, only HMP Berwyn has been built in Wales with 2,106 places and no special provisions for young offenders. The project will be funded by the UK Government and will be budgeted at a medium cost.

End Users

The YOI will be operational 24/7, 365 days a year, as inmates will live on site and staff will be available on site at all times to monitor residents and provide security.

There will be two types of staff: 1. Everyday staff who monitor and work with the residents everyday and interact with them on a daily basis, whilst maintaining the overall security of the complex. Staff will be encouraged to directly supervise inmates, as opposed to indirectly, by actively engaging with their activities - for example, cooking and eating together.

These staff should build a relationship with residents, offering them guidance and building a strong support network.

2. Visiting staff who come in for educational, work and recreational purposes, such as to: teach an English class three times a week; oversee a gardening course; coach a football game; or lead a religious service. Generally, educational and work programmes will take place in the morning, when young people are the most focused, with recreational and physical activities in the afternoon/ evening.

Inmates will also be allowed to leave the complex to attend jobs in the local community (ROTL) but these will be under strict rules and time scales. The ROTL programme will be tailored to each individual inmate, allowing for a mixture of vocational teaching within the institution and application of work outside it.

Visiting hours are focused on the weekend to allow more friends and family to visit and residents to work on weekdays.

THE SITE

Narrative | Site | Scheme | Structures | Environment | Regulations | Process

Spike Island

Spike Island, 1828

Located in the heart of Bristol, Spike Island is bounded by bodies of water to the North and South – The Floating Harbour and the New Cut. It was created when, in 1802, William Jessop was commissioned to stabilise water levels in order for passage of ships, even during low tide. The tidal river water was diverted into the New Cut, whilst levels remain constant in the Floating Harbour due to the construction of Cumberland Basin and subsequent locks. 1

Bristol New Gaol

To the East, on the same road as the proposed site, was Bristol New Gaol. Built using a traditional radial plan, the gaol (jail) has now been demolished except for the castle-like gatehouse. The gaol was closed in 1883, due to poor conditions, and replaced by Horfield Prison (now HMP Bristol). 2 Now, Spike Island is a vibrant destination, characterised by maritime, cultural, industrial, leisure and residential building uses. The harbour edge has “evolved from an inaccessible industrial hinterland to a well-used recreation resource for the city”, with over 80% of it now publicly accessible. 3

Heritage

West of Spike Island, c.1930

The Floating Harbour allowed for large scale import and trade of timber. 4 Spike Island used to be divided into various ‘Wharfs’, named after the sources of timber, such as, Canada Wharf and Baltic Wharf (now the Baltic Wharf Caravan Site). The Cottage Inn was originally the old wharf master’s house and then became May & Hassell’s offices to manage the timber yard. One timber shed remains and is now used by Baltic Wharf Sailing Club, to store boats and, with additions, to provide some indoor space.

The whole of Spike Island has an industrial presence, with Underfall Yard as a reminder of its heritage. Built in the 1880s, Underfall Yard is one of the few remaining working boatyards in England. The site is used as a tourist attraction, with a visitor centre and small cafe, but is also used by the Harbour Master, Docks Engineer and maritime businesses. 5

Listed buildings near the site for consideration include: various industrial buildings, such as Underfall Yard (also a scheduled ancient monument) and Bond Warehouses; workers cottages and Victorian terraces; and Cumberland Basin locks and swing bridges. 6

Future

Flood risk

High risk

Medium risk

Low risk

The Floating Harbour has a stable water level but the New Cut is tidal and fluctuates by nearly 9m between low and high tide.

As a result, the site is liable to a medium risk of flooding and is a moderate hazard. 7

l od wal

o 250m fl

The tidal River Avon also means there is an increased future risk from rising sea levels and storm surges and also increased fluvial flood risks from more intense rainfall. In 2018, there were 1,000 properties at risk from tidal flooding in the city centre, but by 2060 there will be 2,600. The new 250m Cumberland Road flood wall reduces the risk of tidal flooding to around 170 homes and businesses.

1 in 20 year flood level = 8.89m 0.5m rise on site 1 in 100 year flood level = 9.12m 0.75m rise on site Under Draft Policy DS4, the Western Harbour was identified for development as a “new city quarter�, through diverse land use.

Development will comprise: at least 2,500 new homes; improved pedestrian/cycle routes; and reconfiguration of the 1960’s road system. 8 Additionally, a planning application opposite the site proposes 4 new residential units (max. 4 storeys high), and associated parking, infrastructure and riverside footpath. 9

The Site

The site is bounded on two sides by the calming presence of water.

Resident’s personal sense of safety and grounding is aided by observing the passing of time. This is usually achieved through daylighting, but here there is also the potential to use the tidal rise and fall of water.

The site is located by a main road and several pedestrian routes, particularly a strong pedestrian connectivity to the harbourside.

Nearby transport links by bus and boat also help easy access for support networks of friends and family. The site has two existing access points. The accessibility of the site presents the challenge of creating a secure line around the perimeter of the scheme.

The site can also increase public awareness of the prison as it is so prominent within the urban realm. The listed and contextual buildings should be considered, such that the scheme does not change the nature of the environment. The site presents a challenge of overcoming its inward looking nature as this provides a constant reminder of incarceration.

Courtyard - The Urban Realm

The YOI site was selected due to the benefits of an urban setting, such as better access and local community. The challenge of this is the creation of a secure line around the perimeter of the scheme.

Nanterre Prison addresses this by using the building facade itself to create the secure perimeter. The building edge sits on the street front, in line with neighbouring buildings. The fluid facade has been used to create more architectural interest than a traditional, freestanding boundary wall. The building enclosure creates a central courtyard with cells looking into it, so the public do not have a view of the inmates and vice versa. However, inward cells are not ideal as they provide a constant a reminder of incarceration.

The prison wall is the building

Campus - Microcosm of Society

Halden Prison is designed so that inmates can move freely around the site. Building uses are separated by function so that residents have to leave their accommodation, imitating an outdoor commute to work, education and leisure.

The challenge is to create this transition between spaces on a much smaller scale - for 30 inmates as opposed to Haldens’ 250. Some inmates, used to an urban environment, find the silence and quiet of the remote location unsettling and isolation. So the scheme needs to find a compromise between the biophilic approach (integration with nature and the outdoors) and the urban setting.

Building Zoning

The building has been arranged such that spaces meet the levels of privacy they require.

The building itself creates a secure boundary and enclosure around a central garden. Private gardens, intended to mimic a dwelling’s ‘back garden’, create a secure buffer and essentially two secure lines.

The functions are separated into different blocks to create transitions between the spaces, through an outdoor central garden and vertically through level changes.

Circulation

All entrances are on the West side for security and to make East living areas more secure. Staff, inmate and visitor entrances are separated, with pedestrian access set back along the harbourside, as it is the quieter side of the site. Access for vehicles is set back from Cumberland Road, with indoor turning and staff pedestrian access set back from the main road for privacy.

Landscape Strategy The overall strategy is to buffer certain areas of the building with planting, whilst improving the nature of the harbourside and also increasing biodiversity opportunities. Improved pedestrian links, as part of the wider Spike Island development plan, and buff herringbone brick are used to maintain the character of the harbourside. Low level planting outside the entrance will create a doormat and a sense of arrival. Defensive planting, consisting of species found native in a traditional British hedgerow, acts as a buffer to bedrooms and increases security. Thorny and spikey evergreen plants will be used, flowering at different times, with some climbing species, adding visual interest throughout the year.

Dog rose

These will also bring added benefits of biodiversity, producing fruit and pollen for birds and insects. Linking to the external wall, the internal gardens will also use vertical climbing plants, creating small pockets of wildlife habitats and resident social space. In contrast, the kitchen garden will consist of horizontal planting, with a balance between productive and recreational space. Four rotating quadrants provide a variety of plants, maximising the garden’s educational value. Produce will be used by residents and surplus sold to local outlets, such as the Cottage Inn. One quadrant will be left for recreational space as well as central seating.

Mixed Red K-Briq (by Kenoteq) Traditional clay brick manufacturing uses a high embodied carbon, but K-Briq has one tenth of the carbon impact, does not require kiln firing and uses no cement. K-Briq is made from over 90% recycled construction waste and is fully recyclable at the end of it’s life. It looks, weighs and behaves the same as a regular brick but also has the benefit of better insulation properties.

British Western Red Cedar Cladding Providing it’s end of life is considered, timber can have a low embodied carbon. Home grown UK cedar is class 3 durable (moderate - BS EN 350) meaning it can be left untreated to naturally age (turning more grey) and therefore can be carefully removed and reused. The cedar can be sourced locally in Southern England and Wales, which is cheaper than buying and importing from Canada, and with a much lower carbon footprint.

Overall Material Strategy

Industrial history of brick - Bond warehouse and Underfall Yard

The building materials are zoned into public and private.

Institutional spaces are represented in timber and living spaces in brick. The aim is to use domestic scale construction, such as load bearing brick walls, as these are familiar to residents and found locally in Bristol dwellings. The detailing of the brick and its softening with timber will challenge the traditional, austere red brick Victorian prison, whilst also nodding towards the site’s industrial heritage and hisoric timber yards. Timber spaces soften the brick and denote entrances and public outlook. Timber walls to the inside of brick residential spaces articulate these spaces as shared living spaces, whereas brick implies private bedrooms.

Ground Condition

The site is currently surrounded by much hardstanding, such as paving and tarmac car parks. Underneath this, however, the ground is relatively soft, consisting largely of clay, silt and sand.

This soft condition not helped by the close proximity of water on both sides, making the ground more unstable.

Due to these factors, it was deemed appropriate to use ‘mini’ pile foundations, especially as the tallest section of the building is 3 storeys. Deep foundations will also provide the building with more stability in the event of a flood, although the flood risk has been reduced due to a new flood wall, protecting from the tidal water.

Load bearing red brick walls will be utilised. This carries advantages such as inbuilt fire resistance, a well understood construction process and high durability. This build up will be employed around the whole scheme, replacing the outer skin of brick with blockwork, that can later be clad in timber.

Beam and block floors are a common approach in dwelling construction. They are also appropriate in sites where the ground has poor bearing capacity or a high water table and a slab could be unstable. Pre-cast beams and blocks increase speed of construction and standardisation of components creates potential for reuse.

Space underneath the floor must be ventilated so a reinforced screed could be used to ensure the air gap does not create any security concerns.

The primary function of the outer boundary walls is to maintain security. This is achieved through defensive planting and meeting the minimum required height for a low category prison wall (>4m). Above a height of 2.8m, brick articulation is allowed.

The aim of this is to add visual interest to the facade. To meet the scheme’s ethos of sustainable design, broken glass bottles and jars will be used on top of the wall. This avoids the hostile perception of barbed wire or spikes and is significantly lower cost, but still provides an extra layer of protection. The coloured glass would also cast interesting shadows.

Rooftop Sports Court

Rooftop sports court section - 1:10

The open grid VersaCourt tiles allow water to drain underneath them. Water falls onto the screed below (covered by a DPM), falling to the sides to drain away. The tiles are shock absorbing through reverse spring tension expansion joints, reducing impact noise to floors below and creating a pleasant, springy surface for sporting activities. Within the roof, 2 layers of insulation (2 x 120mm) provide additional shock absorption as well as thermal insulation.

An acoustic mat will also be employed, for example ‘soundscreed’, in order to protect against both airborne and impact sound. The thickness of the roof build up is over 650mm, meaning this large mass will also absorb much of the sound.

Mesh fixing

Water travels under VersaCourt tiles to gutter Gutter with mesh over gutter drains further down court

To provide the perception of a brick frame, brick slips will be used to create the horizontal effect. These will be fixed to concrete beams using metal fixings. Within the frame, a metal mesh will be employed to secure the court for residents, for both security and to aid with sporting activities. The mesh will be clamped into a frame, with a welded bar holding this in place. A similar frame will hold the mesh in place at the top.

Daylight

South East glazing

The shading diagrams demonstrate that the central courtyard will have good daylighting for the majority of the year. In particular the most north-east corner will benefit from good sunlight for large parts of the day. The landscape plan has been designed carefully in response to this, with incorporation of shade-tolerant plants to the more shaded south-west and sun-loving to the north-east part of the courtyard kitchen garden.

The scheme employs a modest amount of glazing, reducing potential for heat loss and controlling solar gains. Risk of south overheating is reduced due to small fenestration size and angled windows. West orientated admin spaces, such as archive storage, therapy room and offices will be occupied for traditional office hours and so are less impacted by low evening sun. The rooftop sports court is orientated north-south as this reduces the impact of low sun on play. Education and admin spaces benefit from diffuse north light, which is useful for working visual tasks. This is also advantageous for the entrance block security as it allows for clearer observation for staff. Diffuse light is also provided to resident bathrooms and the library.

Daylight Factor

Neighbouring buildings do not hinder daylighting potential

The site location is highly suitable as there are no buildings to the north or south that present overshadowing daylight issues. The scheme has been designed such that from 2m no neighbouring properties are at an angle greater than 25o, meaning all rooms are capable of achieving good daylighting. If daylighting is sufficient, use of artificial light can be minimised, saving on electricity usage, reducing running costs and potentially decreasing heat gains from lamps, with the acknowledged benefits to mental health.

An example study of daylighting in a typical room:

>25o 2m

A typical south facing bedroom achieves a daylight factor of 2.1%.

This is the natural diffuse light from an overcast sky. The CIBSE lighting guide states that a daylight factor under 2% means a room is not adequately daylit and is reliant on artificial light. As the daylight factor is between 2-5%, the room is well lit, therefore glare and solar gains are unlikely to be a problem, although artificial light may be required for certain tasks.

A bedroom typically needs to achieve 200-300 lux. However, the resident bedrooms function more like study/student bedrooms with a higher occupation and range of room functions, such as reading or writing. Therefore, there should be provision to provide 500 lux task light for more focused and concentrated activity. This will be provided throughout the scheme through various forms of LEDs, designed to suit the function of the space.

Ventilation

The scheme is primarily mechanically ventilated with potential for natural ventilation during the summer. Due to the secure nature, windows on the boundary wall have been designed sensitively.

Opening windows onto the public realm are only permitted in staff-only or staff-monitored spaces, such as the workshop, offices or staff room. The bedrooms achieve user comfort through resident-controlled ventilation panels - the window for daylighting and views is fixed but the panel allows air into the room without comprising security.

MVHR

Mechanical ventilation

MVHR

During winter, an MVHR system will take heat from the kitchen and distribute it into bedrooms. Ensuites stack and extract through flat roofs to the air above. Some spaces will need mechanical ventilation as they generate a lot of heat - eg: gym, IT suite and laundry room.

The majority of inward facing windows are openable, allowing user control to all spaces. The plans are not particularity deep so this allows for natural ventilation when possible, particularly single sided ventilation in spaces such as offices.

Heating and Occupation

The scheme occupancy will vary. House blocks will be consistently occupied as residents sleep and eat in these spaces. Observation rooms will also be largely occupied - as a result these spaces will be heated by water radiators. These will be individually controlled by the user, promoting personal comfort. This function is rarely available in many prisons, with inmates unable to open windows or control temperatures in cells.

A horizontal ground source heat pump will generate enough heat to supply the East house block. The two South blocks have potential for PV panels to heat water. Anti-freeze water runs through a closed loop system, buried 1-2m underground, which will not effect the planting within the kitchen garden, and then run through the radiators. GSHP lowers carbon emissions and are more energy efficient than traditional gas systems.

The non-residential blocks will have fluctuating occupancy. These spaces will be used for short bursts of time but with larger groups of people, such as the visitor centre and classroom. Therefore, these will be heated only when in use through an air source heat pump, but also adequately ventilated in summer when the volume of people could cause overheating.

Plant, risers and storage rooms will be unheated but within the thermal envelope, the machinery itself generating sufficient heat.

Thicker insulation will be incorporated into walls and floors between plant adjacent heated rooms, reducing uncomfortable heat or cold transfer.

Building Fabric

Partial fill cavity wall, 125mm insulation U-value: 0.13 W/m2·K

Composite triple glazed window U-value:: 1.0 W/m2·K

The building will be constructed using a ‘fabric first’ approach, whereby the configuration of the building itself is designed to optimise efficiency. As the building form factor is 2.4, it’s shape lends itself to be energy efficient (a good form factor is under 3). Combined with this, it is of great importance to ensure the building maximises air tightness, utilises super high insulation and a sparing quantity of openings, to achieve a highly efficient building.

Insulation is also essential for heating systems, such as ground and air source heat pumps, to work efficiently as a properly insulated building reduces energy demand, operational costs and heat loss in winter. Thus, the building will be extremely well insulated and achieve great (low) U-values.

The U-values achieved within the building better the guidance set out in Part L2A - Conservation of fuel and power (in new buildings other than dwellings):

Warm single ply roof, 2 x 120mm insulation - U-value: 0.10 W/m2·K

Acoustics

Typical prison wing

The prison sounscape is usually intimidating. Noise is amplified through ‘hard’ architecture (reflective materials, such as metal and concrete) and the noises themselves are often frightening inmates shouting and keys rattling as people are locked up. To combat this, the scheme uses absorbing materials, such as timber.

In traditional prisons, echo and airborne sound is an issue as prisoners are rarely entrusted with a fully sound sealed cell unlike at the YOI. The usual recorded reverberation time (the time taken for a sound to decay in a closed space) inside a prison cell is 2-3 seconds 1, but a comfortable private conversion level is 0.5.-1 seconds. Internal timber walls and floors joints will be sealed well and cellulose insulation will be a minimum thickness of 100mm and minimum density of 10kg/m3 laid in the cavity.

metal and concrete reflect sound

Other materials are employed to reduce impact noise from sports provisions. TVS Sportec rubber flooring will be employed as a floor finish within the gym because it absorbs vibrations, is durable and is made of recycled rubber mixed with EDPM colour granules.

The equipment layout can also be designed so anti-vibration pads are under machines that cause particular stress.

Material Strategy

Materials and construction techniques have been selected to maximise their value and minimise waste. The ethos is that of a circular economy, through minimising new elements introduced and reusing materials where they are already available.

Re-purpose and Repair The scheme has been designed such that the building is versatile and flexible for future use. For example, house blocks could be repurposed into student accommodation or sheltered living for the elderly with little modification. Elements such as cladding can be re-clad or repaired when needed due to the blockwork structure.

Reuse Through standardisation and established construction methods, (eg: pre-fab beam and blocks) if carefully removed, components could be reused in other buildings once the building reaches its end of life.

Recycle and Reduce Using recycled and untreated components reduces existing and construction waste - for example 90% recycled K-Briq.

Circular material cycle - aim to reduce pollution and waste in landfill

80

Narrative | Site | Scheme | Structures | Environment | Regulations | Process

Plant

The building has a main plant room within the admin block, where most of the building services are controlled. Each block then has an individual plant room and subsequent riser to meet the specific needs of the block.

As the main plant room cannot extract to the roof above due to the rooftop sports court, to avoid having an extract on the side of the building, the pipework ducts through the staff corridor on the first floor and then up to the roof.

Energy demands for the building will be offset using renewable technologies, such as GSHP and PV panels. To offset the impact of building within a flood risk area, the scheme aims to benefit the local water source. This could be implemented through the use of a packaged wastewater treatment system, where sewage is treated in order to release clean water back into the Floating Harbour. Reed beds could also be employed to clean wastewater and general pollution, using zero energy and also benefiting the local ecosystem.

Flood Strategy

fixed Floating Harbour water level

+0.5m

The site has a medium risk of flooding, with a 1 in 20 year flood rise of 0.5m on site and a 1 in 100 year flood rise of 0.75m. As a result, the scheme has been designed such that the majority of the ground floor level is raised 0.5m above the existing - this also has the benefit of increased privacy as residents and the public will not be at the same eye level.

maintain boat access

The +0.0m spaces are designed to have sacrificial floor finishes, such as treated concrete floors, which can be easily cleaned, and comprised of flood resilient materials with low permeability, such as lime plaster. Most of these spaces, except visitor centre and reception are storage or circulation spaces, meaning they are hierarchically low impact if flooded. All sensitive and electrical items, such as plug sockets, will be raised as high up as possible to protect them from the risk. In the event of a flood, a plan and strategy can be employed when the building is in use, such as deploying sandbags or temporary flood gates into openings.

potential reed beds

Through increased soft landscaping, planting and green roofs, the scheme reduces surface run off. As the site currently consists of existing hard landscaped car park, the proposed scheme should be an improvement on existing conditions and made easier for water to drain away after a flood. The risk is also reduced through the new flood wall built in 2016, adjacent to the site. If the site is to be developed, it is arguable that building typology is appropriate because instead of building houses, a place of detention is a lower priority for the community.

Pitched 10o roofs

Pitched roofs 1kW (output for 1m2 PVs) x 162m2 (of PV panels) x 0.2 (20% efficient) x 4.3 (average sun hours/day) = 140 kWh per day Flat roofs 1kW (output for 1m2 PVs) x 345m2 (of PV panels) x 0.2 (20% efficient) x 4.3 (average sun hours/day) = 295 kWh per day This is a simplified calculation and does not account for various factors, such as overshadowing, but an average day could see 435kWh generated. An average person in the home uses 10kWh per day, thus with a resident population of 27, plus additional staff and visitors, the PV panels could offset the electricity usage at some points of the year.

Biodiversity

Overlooked roofs will be extensive green roofs, adding aesthetic appeal, benefiting biodiversity and reducing water run-off.

Some roofs are north facing and the entrance roofs will undergo some shading from neighbouring buildings. As such, the seed mix needs to be shade-tolerant and compatible within an urban environment. The roofs will be designed with the ethos of a ‘brown roof’, whereby the biodiversity found within them is similar to a brownfield site. Spaces will be left to germinate with local wind transported seeds and the roof will develop over time as part of the local ecosystem. A mixture of species will enhance roof performance and make it more stable.

However, for those arriving by vehicle, there is a car park with access along the harbourside or nearby on road parking. There is potential for designated disabled parking bays within the site. pedestrian access along harbourside from car park

There is a level approach to the site with a level threshold into the building. Weather protection is provided to the key building access points - eg: recessed doorways, covered entrances and a sheltered colonnade. All external doors are at least 1000mm wide. +500mm

A large proportion of the building is raised by 500mm. This change is dealt with by a 1:15 ramp and short flight of stairs for shared inmate and staff use. The 1500mm wide ramp is supported by handrails on both sides, with a 1500mm long landing in the middle. At the staff only back entrance, stairs and a platform lift are used. Visitor access is completely level, with level access between the visitor centre and garden - supporting wheelchair and prams.

All non-residential block floors are fully accessible, via passenger lifts/one staff-only platform lift - which all meet the minimum required dimensions. Wheelchair-accessible unisex toilets are also supplied for staff, visitors and residents on every floor, in these blocks. Wheelchair-accessible bedrooms are limited to the ground floor, but if wheelchair access to the first floor was deemed necessary for staff, there is space provision at the end of corridors.

3 out of the 27 bedrooms are wheelchair-accessible (minimum 1 out of 20 required in M1 4.24). Emergency assistance alarms will be provided in all bedrooms. To assist the partially sighted, bedroom doors vary - eg: different colours and embossed room numbers.

Part B - Fire

B.015 considered, the scheme endeavours to meet Part B requirements, especially considering it’s ‘end of use’ plan, whereby it could be re-purposed with a different use, such as student accommodation.

B2: Internal fire spread (linings) Internal linings (eg: ceiling plasterboard) will be fire resistant up to 30 minutes, and exposed timber roof joists will be treated with fire retardant coating.

The building is classed as Purpose Group 2(a) - Residential (institutional). The document HMPPS Custodial Premises Fire Safety Design Guide identifies risks from fire and details subsequent preventative and protective measures - such as emergency procedures for cell fires and training in RPE (Respiratory Protective Equipment) for safe prisoner evacuations. An assembly point will be identified within the central courtyard from which there will be a secure, controlled evacuation. Fires within prisons are almost inevitable, with “2,580 fires in prisons in England and Wales in 2016 – almost 50 a week” 1 - therefore, it is important to have both fire management and construction strategies that mitigate the risk.

B3: Internal fire spread (structure) External blockwork walls and concrete beam and block floor construction will help reduce spread of fire, but masonry construction does create potential for spread of smoke and fire within cavities - thus, sufficient cavity barriers will be employed, providing at least 30 minutes fire resistance.

B1: Means of warning and escape Automatic fire detection and alarms will be employed in all rooms of the building. All rooms meet the requirements for the maximum travel distance to an exit - 35m in all, except 18m in bedrooms (which all exit onto protected corridors). All escape routes are at least 1200mm wide, with exit signs and escape lighting, leading to minimum 1000mm wide doors. Protected corridors and stairs have a minimum period of 60 minutes fire resistance, assisted with sprinkler systems. Protected stairs in non-residential blocks also include refuge for wheelchair users. The protected stairs and fire exits escape into enclosed spaces (i.e: the courtyard) with the length of the external space exceeding the height of the building.

86

B4: External fire spread Fire spread risk is reduced due to the limited number of buildings adjacent to the site and their non-combustible nature (eg: masonry).

B5: Access and facilities for the fire service 60% of the perimeter (minimum 15%) has clear access to 3.7m around the building for Fire and Rescue. Fire vehicles should not be expected to reverse more than 20m so sufficient space for vehicle turning circle at the end of the route is provided.

B.015 “Prisons are exempted from the functional requirements of Parts B1 to B5 of the Building Regulations under section 33 of the Prisons Act 1952. It is usual that prisons should comply with the fire safety requirements of the Building Regulations, except where the requirements are incompatible with safe custody, good order or security.�

Construction Design Management

CDM (Construction Design Management) is a set of regulations intended to maintain health and safety during the development, construction and maintenance of a building. When considered during the scheme design rather than as an afterthought, the safety on site and in use is improved.

Security Many new prisons encounter public opposition - for example, in 2019, protestors halted construction and occupied the site of HMP Wellingborough for 6 hours 2. To minimise the threat of disruption and protect persons on site, an opaque, high fence should be erected around the site. This is also required to avoid the public seeing how the complex is arranged – for security reasons, many prison plans are restricted from the public.

Traffic routes The pedestrian routes around the site, particularly along the harbourside, will be diverted so the public have minimal exposure to the site. To the South, Cumberland Road is not a primary A-road but has several bus routes – for some phases of construction, traffic may have to be diverted or changed to single lane.

Restricted Site The site is in close proximity to nearby buildings and vehicle access is only from one side. Phase 1 will be the tallest part of the building (Admin Block) and will require a crane. Phase 2 is more standardised, residential, 2 storey construction. Portacabins with sanitary and washing facilities will be required on site.

Water As the site is bounded by water to the North and South, precautions should be taken to ensure personnel safety, in the form of guarding and rescue equipment. The water also presents a flood risk, so a ‘flood plan’ should be created – detailing precautions, such as keeping sandbags on site.

Maintenance It is important to maintain security, whilst allowing works to be carried out. Most windows and gutters can be cleaned by securitychecked maintenance staff, using ladders. Scaffolding may be used to maintain the taller Admin Block, ideally on a weekday or when the harbourside is less busy as the footpath may have to be temporarily closed.

Measures must be taken to maintain site security (Protest at HMP Wellingborough construction site: 2019)

Further Regulations

Part E - Sound Airborne sound and impact sound (that travels through structures and objects) is considered. Well-sealed joints to internal walls and floors will help maintain privacy, particularly in spaces such as bedrooms, with additional insulation around plant rooms.

A double layer of insulation will be employed (2 x 120mm thick) will be used underneath the rooftop sports court, as rooms below are especially vulnerable to impact sound. Impact sound can also be reduced through soft coverings - despite timber floors, rugs, bedding and other soft furnishings can achieve this.

Upon completion, testing should ensure the sound insulation demonstrates Part E compliance. Testing is particularly important in residential rooms - eg: bedrooms and living rooms. The YOI does not share any party walls and external spaces are either self enclosed (kitchen garden) or elevated above the public (sports court). Therefore, noise travel from these should not be an issue.

Prison Regulations It is important to note the separate regulation documents for prisons, such as documents by National Offender Management Service (NOMS) and the UN Technical Guidance for Prison Planning - which include minimum requirements for spaces (such as dimensions and ventilation requirements). Matter Architectureâ&#x20AC;&#x2122;s Wellbeing in Prison Design: A Guide also suggests design approaches to alleviate the common problems in traditional prisons and design to support rehabilitation.

The United Nations Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules) The Nelson Mandela Rules are regulations for care and facilities that should be provided and met in all places of detention, globally.

For example, rule 11 details the categorisation of prisoners and how â&#x20AC;&#x153;Untried prisoners shall be kept separate from convicted prisonersâ&#x20AC;? 3 (11.b) . The scheme is assumed to house only convicted residents, as in England and Wales only 11.2% of the total prison population was on remand 4 (yet to be tried), but the nature of the self contained house blocks would facilitate segregation, if required; through rotating zoning management and careful timetabling of communal facilities.

Pandemic

Recent events made me consider how the scheme would function in a pandemic situation, such as the current Covid-19 outbreak.

In April, the Ministry of Justice said 4,000 prisoners â&#x20AC;&#x153;who were within two months of their release date and had passed a risk assessmentâ&#x20AC;? were eligible for early release, but at the time of writing (May 2020), only 55 have actually been released 1.

Perhaps, due to the low risk category and relatively short sentences of the YOI residents, they would all have been released. Maybe the empty rooms would then have opened to key workers - it is only a 10 minute journey to the nearest NHS hospital.

But assuming the residents stayed - likely as over 40% of prisoners have nowhere to live after release 2 - the YOI could be managed such that the 3 house blocks isolate from each other, in effect becoming self-contained households (similar to the categorisation idea on page 91). The small scale of the YOI is beneficial as the spread of the virus would not have the same implications as in a typical large UK prison. Ironically, the whole project has been about avoiding the traditional prison cell of self-isolation.

Re-defining

Week 2 - sport facilities dominate the plan

Initially, the brief incorporated one indoor and one outdoor sports court. Looking at the resulting zoning of the building, the hierarchy of these spaces took a large proportion of the space, particularly on the ground floor. Although it was decided that â&#x20AC;&#x2DC;activityâ&#x20AC;&#x2122; space was the important space within the scheme, as it aids rehabilitation the most, the sports component of the brief was becoming too consuming - it looked more like a sports facility than a residential institution. Therefore, the need for both an outdoor and indoor pitch was amended so only one was required, allowing more dedicated outdoor space to other productive activity, such as the kitchen garden.

It is hard to design a building without turning to personal experience of what we know. In the UK, prisons are tall, flat roofed institutions and I found it difficult, initially, to move away from this mindset. After the first interim, I began looking at the scheme with a new attitude - viewing prisoners as residents and the building not as a traditional prison. I had to re-evaluate my approach, ensuring I was looking to more of a Scandinavian approach as opposed to what was familiar to me.

The context adjacent to the site is fairly low rise, but there are industrial buildings of 8 or 9 storeys in the wider Spike Island community. Trying to achieve a building of several storeys became challenging in how security was maintained in stair/lift cores without aesthetically reading as too institutional. After a few weeks of research and development, I was confident that a building of lower height was desirable. To achieve this and facilitate the whole programme became a challenge and so the site was extended into the neighbouring car park to the West.

Entry

Week 3 - access to the East, awkward angle for vehicle turning

How the scheme is accessed by the various user groups was crucial in the design development. The entry points must be clear to users but also maintain a level of privacy and security.

Cumberland Road presented challenges as it was inappropriate for direct vehicle access as it has a consistent traffic flow, which could compromise security. Pedestrian access also felt too exposed from this main road and the majority of pedestrian footfall was along the harbourside.

Originally, the site entry was on the East side of the side, as the existing parking was to be maintained in the West. There was much debate into the best way for vehicles to enter the complex. It was decided vehicles needed to be able to turn around within the safety of the complex - vehicles would often be used to transport inmates (eg: to and from court) so reversing out backwards put staff in a vulnerable position.

When the decision was made to extend the site Westwards, it presented new opportunities for access. The existing East road to the harbourside was to be maintained, but this proved either too narrow or awkwardly angled to achieve vehicle access. Taking the vehicle access away from the East allowed the road to become pedestrian only, avoiding a â&#x20AC;&#x2DC;back alleyâ&#x20AC;&#x2122; feel and creating a generous promenade opening up to the harbour. Vehicle access was studied to decide whether a fenced external area or roofed internal area would be most appropriate.

Week 4- access to the West, study of enclosed vehicle area

The most public entrance was the visitor entry towards the harbourside and its interaction with staff and inmate access was explored. Was it secure for staff, visitors and inmates to share an entrance?

Approach

week 4

Due to the small institution size and the site’s urban nature, a courtyard typology was initially investigated. The idea of ‘Hortus Conclusus’ was investigated, whereby an inward looking, enclosed garden is hidden from the outside. Comparisons were drawn from the nature of prison to a monastery, as both typologies are inward looking and enclosed in nature - such as: the church as ‘activity’ space (eg: sports hall); the chapter house as administration; and dormitories as bedrooms. This assisted with building zoning, however, a key idea of movement between different buildings had been lost. This resulted in looking more towards the campus typology. The building mass was divided into blocks to achieve the separation, whilst keeping the cloister to join them, and maintaining a central ‘outdoor room’. To get away from the institutional courtyard mindset, roof pitches were introduced into the scheme, in response to the context. After the second interim review, the massing and general organisation stayed very similar.

Making

Week 6 - rooftop sports court from interim 2, section and elevation

Looking to the industrial context for inspiration, the presence of warm red tones was something I was keen to incorporate into the design. At the beginning, I was debating achieving this through brick or metal cladding (such as copper or corten). Although I thought these the most appropriate given the site location, I was cautious about utilising such stereotypical ‘prison’ materials.

Through introducing timber and developing detailing, the nature of the building was softened.

The scale and arrangement of the house blocks were designed to be repeatable, although this was challenging given their different orientation. Achieving an ethos of simple load-bearing construction presented a challenge in non-residential blocks, requiring larger spans.

Aesthetically, the buildings roofs changed drastically over the course of the design. Initially, to come away from the stereotypical ‘flat roof ’ institution, pitched roofs were investigated. Hip and gable roofs were appropriate as they were prevalent within the context. However, this created a lot of height, particularly where the roof structure was to be extended over the rooftop sports court.

It was decided that as residential dwellings are often characterised by pitched roofs, the activity and administration parts of the scheme could be represented by flat roofs.

Reflection

Towards the end of the project I read ‘A Bit of a Stretch: The Diaries of a Prisoner’, by Chris Atkins, which was released in February 2020. Amongst the sad, shocking and often bizarre accounts, his stories of how prison was “brutalising teenagers” reinforced the importance of this project for me. “Anywhere else they’d be treated as human beings who needed urgent medical help. But because they were in prison, often on pathetically trivial offences, they were shouted at like animals and locked up determinately in a concrete box.” 3 But, as Atkins says, “why on earth should law abiding citizens concern themselves with what happens to a bunch of criminals?” 4 Well, firstly, as humans I believe we owe everyone a duty of care and minimum levels of decency. We should not treat another differently to how we would expect to be treated ourselves.

Secondly, money. The cost of reoffending is 3 times the annual prison budget - it costs more to house prisoners in an old Victorian cell than within an open prison. 5 I went on to find that 50% of HMP Bristol prisoners are classed as Category C/D 6, yet they are housed in a Category B facility.

I truly believe that a new approach to rehabilitative prison design is long overdue and that everyone should be a little more mindful to how the prison system is run.

100

This project challenged me in many ways, pushing me out of my comfort zone with the hope of tackling problems head on. Even though I thought it was the most appropriate solution, I did resort to using a construction method I was very familiar with from placement experience, and so it might have been interesting to detail something other than masonry.

There are still elements of the building I would have loved to develop further. For example, in earlier sketches I was considering some sort of covering over the rooftop sports courts to make it more usable, by protecting it from rain and balls being thrown outside.

During my 4 years at Bath, I never had a problem meeting deadlines, never worked through the night, and never worked later than midnight. I credit this to my stringent time management and selfimposed timetable, but my methodical approach has sometimes curtailed my creativity. In this project, I have tried to be more selfcritical and make more time where necessary to develop a project I am now proud of.

On a personal level, public speaking has always been a challenge for me, particularly at the start of the degree. I would have loved to present my work at a Final Review, as I am proud of how my abilities have grown. I now feel confident to discuss my work with enthusiasm and counter any critiques.
