NATIONAL MUSEUM WALES AMGUEDDFA CYMRU

Estate Strategy Plan Location: Cardiff, Glamorgan

National Museum Wales comprise a group of seven museums, including the National Museum Cardiff, St Fagans National Museum of History and Big Pit National Coal Museum. Their mission is to preserve, interpret and promote the cultural heritage, history and natural environment of Wales for present and future generations.

A thorough understanding of the museum’s vision, financial constraints and timeline has been fundamental to shaping the estate management plan. Initial project phases focus on the east and south wings, prioritising a full service replacement ahead of the museum’s centenary celebrations in 2027.

DB3 is collaborating with National Museum Wales to develop a comprehensive estate management plan for the Grade I listed National Museum of Cardiff. This ten year strategic plan outlines the long term development, conservation and operational management of the museum. Key areas of focus include ongoing maintenance, and restoration to accommodate the museum’s evolving needs while ensuring optimal space utilisation, financial sustainability and compliance with heritage and regulatory standards.

Beyond essential upgrades, a comprehensive reconfiguration and refurbishment strategy is being developed to optimise the museum’s functionality. Budget considerations are central to this process, particularly as the safe removal, transportation, and storage of specialist collections alone exceed £250,000. DB3 is actively working with the trust to develop a sustainable funding strategy, implementing a staggered approach to project delivery to ease financial pressures.

Gifted to the people of Wales in 1907, the National Museum Cardiff holds cultural and historical significance. With this legacy in mind, the project’s objective is to enhance accessibility, sustainability, and inclusivity, ensuring the museum remains a welcoming and functional space for everyone in Wales for generations to come.

To ensure financial sustainability, DB3 is partnering with specialist consultants to identify and enhance revenue-generating opportunities.

This includes the refurbishment and strategic enhancement of visitor facilities, such as the museum’s restaurant, café and retail spaces.

Located in the heart of Cardiff’s civic centre, the museum houses Wales’ national collections of art, geology and natural history, alongside major touring exhibitions and temporary displays. The building encompasses over 700 rooms, including grand halls, gallery spaces, research facilities, conservation laboratories and administrative offices. Additionally, the museum hosts a diverse programme of events, conferences, weddings, private viewings and film productions, making it a dynamic cultural hub. Due to the museum’s intensive operational schedule, DB3 is closely collaborating with the trust to establish a phased programme of works that minimises disruption to daily activities.

The museum’s Grade I listed status requires close collaboration with key heritage organisations, including Cadw, to ensure that all interventions respect and preserve the building’s architectural integrity while improving visitor accessibility and engagement. Over time, various wings and theatres within the museum have been gifted by private benefactors. In such cases, DB3 works directly with stakeholders to align modernisation efforts with their legacy and intent.

Beyond essential upgrades, a comprehensive reconfiguration and refurbishment strategy is being developed to optimise the museums’ functionality. Budget considerations are central

PEMBROKESHIRE COUNTY COUNCIL

South Quay Redevelopment Location: South Quay, Pembrokeshire Expertise Area: Architecture, Conservation Architect & Visualisation

We are transforming a historic area adjacent to Pembroke Castle with modern insertions while conserving several Listed buildings and retaining the medieval burgage plots, in order to create a new visitor centre and community facility Following a positive reception for the masterplan, we were then instructed to develop the design for the first phase of buildings adjacent to the castle.

This phase includes the creation of a Henry Tudor

Visitor Centre, café and library facilities.

The £6 million scheme consists of a combination of refurbishment, extensions and newbuild structures. It has been sensitively designed to retain the most historic structures and medieval burgage plots while providing usable gallery space and maximising estuary views for the café.

Additionally, we assisted Pembroke Council with a bid for Levelling Up funding for Phase 2, which involves the creation of a community hub through a mix of newbuild and refurbishment. Our support included developing a brief with stakeholders and preparing a concept design, including 3D visuals of the proposals. The bid was successful, securing £4.1 million for the project.

Pembroke has some major advantages as a tourist destination, however, South Quay town centre has suffered from economic decline over the last 25 years, leading to the decay of several historic buildings close to Pembroke Castle and the quayside, which once served it.

RHONDDA CYNON TAF COUNTY COUNCIL

Pontypridd Public Realm Location: Pontypridd, Glamorgan Expertise Areas: Architecture, Visualisation, Landscape Design In the heart of Pontypridd, a key site between the High Street and the River Taff is set for transformation. Once home to Marks & Spencer and Dorothy Perkins, the site has stood empty for years. Recognising its potential, Rhondda Cynon Taf Council has approved plans to replace the vacant buildings with a new public realm space, creating a stronger link between the town centre and Ynysangharad Park.

This project will introduce a tiered public space with three levels, connected by sloping pathways and steps to improve pedestrian movement. The area will be landscaped with trees and greenery, offering a more welcoming environment. Two small pop-up units will provide space for cafés or takeaways, adding to the vibrancy of the space, with seating areas encouraging people to gather and spend time in the town. Crucially, this development also enhances the key pedestrian route between the railway station and the Lido, making the town more accessible for residents and visitors alike.

Collaboration with local businesses, accessibility groups, and neighbouring property owners has played a key role in shaping the project. Party Wall Agreements and discussions with stakeholders continue to ensure the development integrates smoothly into the surrounding area.

By replacing long-vacant buildings with an open, well connected space, this project will help reconnect Pontypridd’s town centre with its natural surroundings. It marks a shift towards a more accessible and welcoming urban environment, encouraging people to move through and engage with the town in new ways.

Regeneration & Masterplanning

Delivering this vision comes with challenges. The site sits on a 19th-century bridge now overlaid with concrete, requiring careful structural planning. Flood risk is another key consideration, as the lower part of the site lies in a flood zone.

Measures are in place to ensure compliance with Natural Resources Wales guidelines, preventing any impact on the river or increasing flood risks elsewhere.

CITY OF WOLVERHAMPTON COLLEGE

Wolverhampton Central Learning Quarter Location: Wolverhampton, West Midlands Expertise Area: Architecture, Lead Designer, Client Advisor & NEC Supervisor

DB3 were appointed as architects and lead designer in 2017. We led the concept design options, collaborating with multiple stakeholders, including Wolverhampton Council and the College.

The primary objective for the investment is to regenerate the city centre and provide a focal point for the community to become more involved in the pathways to economic growth.

Planning for the scheme was achieved in August 2019 and the project started with the demolition of the former Faces Nightclub. Due to the Covid-19 pandemic and funding requirements, the project was paused for a number of years. The project is being funded through a combination of Government grants (including Levelling Up Fund Round 1, Towns Fund, Department for Education) and Council contributions. In September 2023, City of Wolverhampton Council’s Cabinet approved a revised budget and funding strategy to ensure the new City Learning Quarter main site is completed for the start of the 2025/26 academic year.

The new city centre campus represents a bold step in transforming the student experience, positioning the college as a leading education provider for Wolverhampton and the wider region.

The campus will serve over 2,000 students and nearly 200 staff, offering cutting-edge facilities

designed to empower learners with the skills and knowledge they need to succeed. Thousands of students and apprentices will benefit from this modern learning environment. The project also aligns with the city’s broader goals of revitalising the community and fostering economic growth.

The purpose-built, four storey campus will house a variety of subject areas. This ambitious project has been made possible through collaborative funding. An initial investment of £6.2 million from the City of Wolverhampton Council and Black Country Local Enterprise Partnership supported key preparatory work, such as design development, site surveys, ground investigations, site acquisition and clearance.

By consolidating outdated facilities and creating a modern campus, the City Learning Quarter will play a vital role in Wolverhampton’s educational and economic future. It aims to empower students with the skills they need for successful careers while supporting the city’s broader goals of regeneration and growth.

In addition to the new facilities providing educational benefits for the city, the City Learning Quarter will generate and safeguard 750 jobs in the local economy. City of Wolverhampton College forecasts that over a 10-year period approximately 45,000 people will benefit from learning at the City Learning Quarter and around 7,500 apprenticeships will be started. It is calculated that through energy efficient buildings and traffic reduction, more than 600 tonnes of CO2 emissions will be prevented from being released into the atmosphere each year. It is also estimated that the Wolverhampton air will be cleaner due to 310kg of Nitrous Oxide (NOx) particles not being discharged into the city.

DB3 have been retained by the client during construction of the project and now act as the Client Advisor and NEC Supervisor.

Regeneration & Masterplanning

Wolverhampton’s £61m Central Learning Quarter project is a transformative regeneration initiative which aims to bring together the City of Wolverhampton College, a new Sixth Form Centre, Wolverhampton Adult Education Services and the Central Library onto a single city centre campus.

The project encompasses the design, remodelling and repurposing of both new and existing buildings, including Listed structures, to create state of the art teaching and training facilities.

A reordered public realm will unify the campus, enhancing its role as a central hub for learning and community engagement.

The development will also incorporate mixeduse spaces encompassing residential, retail and leisure areas.

BRADFORD COUNCIL

Bradford Sport & Wellbeing Infrastructure Location: Bradford, West Yorkshire Expertise Area: Architecture

Of the four schemes, two have completed and provide significant benefit to the residents of south Bradford : Sedbergh Leisure Centre at Low Moor, and Wyke Community Sports Village. The Nelson Street proposal was shelved due to this strategic site being sold to the DfE. A new facility at Squire Lane is due to incorporate Primary Care NHS services as well as the leisure centre. Multiple consultation exercises have been undertaken throughout RIBA Stages 0-2 with concepts and ideas being showcased to the myriad stakeholders.

Sedbergh Leisure Centre is a brand new facility designed to enhance community wellbeing and encourage participation in sport and physical activity across the district. This high quality wet and dry sport and leisure facility serves Bradford’s diverse population, providing accessible, modern spaces for people of all ages and abilities. The centre features a six lane, 25 metre swimming pool with a wheelchair access lift, alongside a 12.5 by 8 metre learner pool with a movable floor. To support both casual swimmers and competitive training, a wet change village and group changing facilities were incorporated. The leisure centre also includes an eight court sports hall with accompanying dry changing facilities, a large 80 station gym, two flexible dance studios, and a dedicated spinning studio. Additional amenities include a meeting room, a spacious reception and entrance foyer, outdoor changing facilities with direct access to external pitches, as well as staff

offices and administrative spaces.

Since opening in 2019, Sedbergh Leisure Centre has had a significant positive impact on the local community. Within its first few months, the centre attracted approximately 3,700 gym members - double the figures of previous facilities demonstrating the demand for sports and leisure spaces in the area.

Building on the success of Sedbergh, DB3 worked with Bradford Council to deliver Wyke Community Sports Village, a project providing a much needed community sports facility. Designed to replace the closed circuit cycle track, this development ensures that sporting opportunities remain available for local residents. The project includes a lit circuit cycle track and additional cycling facilities, outdoor sports pitches, a floodlit artificial grass pitch and amenity grassed areas for recreation and community use. A new pavilion building was constructed to house changing rooms and community spaces, alongside associated parking, external lighting and general maintenance and emergency access routes.

The delivery of Wyke Community Sports Village marks another milestone in DB3’s ongoing collaboration with Bradford Council, reinforcing a shared commitment to regeneration, community engagement and accessible sports provision.

By creating high quality, inclusive leisure environments, these projects are not only improving health and wellbeing but also fostering a stronger, more active community for future generations.

RHONDDA CYNON TAF COUNTY COUNCIL

Llys Cadwyn Location: Pontypridd, Glamorgan Expertise Area: Multidisciplinary Design Team Lead & Architecture Rhondda Cynon Taf County Borough Council appointed DB3 as the lead multidisciplinary design team for the £38 million Llys Cadwyn redevelopment. DB3 acted as both the architect and lead consultant for all RIBA Stages.

Rhondda Cynon Taf County Borough Council acquired the site in 2011 with a view to creating a public sector focused scheme. The solution for the site is based on a mix of uses with the preferred option for an employment based development with three new buildings that allowed the opportunity for new public spaces, and new views of the wonderful Ynysangharad Park.

The redevelopment includes: two new office blocks, 21st-century library, council customer contact point, café, community facilities and leisure and fitness centre.

The project has revitalised the area by creating an attractive riverside promenade and providing 14,693 sqm of office space for over 1,000 people, resulting in substantial economic benefits that position Pontypridd as a strategically important town in the region.

The scheme comprises three buildings. The first one serves as the headquarters for Transport for Wales (TfW). The second building has office space that accommodates 400 staff alongside an accompanying café. The third building is ovular in shape and houses the library, council customer contact point and leisure and fitness centre. In addition, the areas in and around the premises have been improved and are open to the public, including a new Taff Vale walkway that runs alongside the river. A pedestrian bridge has been constructed over the River Taff, connecting Llys Cadwyn with the Ynysangharad War Memorial Park.

The successful completion of the project involved overcoming several technical hurdles that demanded a highly cooperative and interdisciplinary approach across all three buildings. These challenges included navigating

Covid-19 restrictions and mitigating the flood damage caused by Storm Dennis. Additionally, while the Llys Cadwyn site was not situated within a conservation area, it was bordered by such areas and listed buildings, which required meticulous consideration.

To achieve the unique appearance of the ovular building, it was crucial to employ an accurate engineering approach. The construction involved utilising a steel skeletal frame, which was carefully designed to accommodate the curved walls. To cover the frame, precision-engineered timber panels made of laminated veneer lumber were overclad. The curved steel frame originates from the reinforced concrete core, and it provides the necessary support for prefabricated timber cassettes that are bolted back to the steel. In total, the project incorporated 6,345 zinc shingles, each roughly the size of a ceiling panel. The internal structure of the building presented its own set of challenges. As the gym and activity studio were located above the library, managing vibration and acoustic control in long-span steel beams (up to 15m) was a significant issue that required careful design solutions from our team.

The project generated more than 3,987 weeks of training opportunities, which included 834 weeks of training for individuals who were long-term unemployed, 957 apprentice weeks and 201 weeks of work experience. Additionally, the project prioritised local employment, with 67% of the workers residing within a 40 mile radius of the site. Over 60% of the project’s expenditure was also within a 20 mile radius. Overall, the project produced a social return on investment of £12.6m.

The development has been highly commended in the British Construction Industry Awards. It has won awards for Transformation, Winner of the Winners, Creating Economic Growth, and Development of the Year. Furthermore, the development has exceeded expectations by achieving a BREEAM rating of ‘Excellent’.

RHONDDA CYNON TAFF

Robertstown Development Location: Aberdare, Rhondda Cynon Taf Expertise Area: Architecture As part of a wider regeneration initiative in Aberdare, we were appointed as architect for a 2,000 sqm development of business starter units on former railway land at Robertstown.

This regeneration effort aims to transform underutilised sites into thriving hubs of economic and community activity, enhancing the local area’s vitality and opportunities.

Our design approach aligns with the regeneration goals by prioritising tenant attraction and community cohesion. Moving beyond the standard design for light industrial units, the layout arranges the units on either side of landscaped pedestrian streets, fostering a sense of community and accessibility. The buildings’ asymmetrical shapes allow for future expansion with mezzanine floors, while the use of brightly coloured accent details against black cladding adds visual interest and identity to the development.

The project also embraces sustainability, being highly energy efficient and achieved a BREEAM ‘Excellent’ rating. This reflects the broader regeneration ethos of promoting environmentally conscious growth while creating spaces that cater to diverse business needs.

Regeneration & Masterplanning

The Robertstown development comprises 20 light industrial units designed for small and start-up businesses. The site, a flat, overgrown, elongated area of allocated employment land, presented several challenging site conditions during the design stage, including the presence of Japanese knotweed, mare’s tail, nesting birds, reptiles and potential issues with site contamination and flooding.

Stadium Led Regeneration Location: Scotland Expertise Area: Architecture

Our primary focus was identifying new locations for a stadium that could also drive long term economic and social benefits for the surrounding area. The goal was to create a development that not only supports the club’s ambitions but also contributes to broader community growth.

We assessed five potential sites, developing diagrammatic solutions that allowed the club to explore all options with greater flexibility in negotiations with landowners. This helped ensure that the club could secure a location that would facilitate both immediate and future growth.

Leveraging our extensive experience in diversifying football facilities, we engaged representatives from a wide range of sectors, including the NHS, housing associations, and hotels, to assist in developing a business case. This collaborative approach helped to accurately estimate the potential income of the proposed facility.

In addition to ensuring a sustainable cost plan, we expanded the initial diagrammatic floor plan into 3D visualisations and detailed floor plans.

The presentation of these provides the club and its members with a glimpse of what the new stadium might look like, a radical departure from the traditional architecture seen in the Scottish Premiership.

In undertaking this project, DB3 committed to fostering positive community relations and ensuring that the new stadium serves as a catalyst for local economic growth and social cohesion.

Plans are in place to engage local stakeholders through public consultations, ensuring that the community’s needs and insights are integral to the development process. Additionally, the project is anticipated to create numerous job opportunities during and after construction, substantially benefiting local employment rates.

DB3 is dedicated to sustainable development, with a keen focus on incorporating eco-friendly materials and technologies into the new stadium’s design. Preliminary environmental impact assessments have been conducted and strategies for energy efficiency, waste reduction, and minimal environmental disruption are being rigorously developed.

The design of the new stadium incorporates cutting edge technology to enhance fan experience and operational efficiency.

Innovations such as high efficiency lighting, rainwater harvesting systems, and smart building management systems are being considered.

Regeneration & Masterplanning

DB3 was appointed by a Scottish Premiership club to explore options for either refurbishing their current stadium or relocating to a new site.

The club’s existing facilities are limiting their operations and potential for revenue generation, while the site itself is constrained in terms of further development. Any redevelopment would also require the club to temporarily relocate.

THURROCK COUNCIL

Culver Centre and Culver Field Regeneration Location: South Ockendon, Essex Expertise Area: Architecture, Masterplanning, Landscape Design Urban regeneration is key to revitalising communities, addressing housing shortages and creating sustainable, inclusive environments. In South Ockendon, Essex, additional housing was needed to increase provision while maintaining and improving existing housing stock.

Access was a key constraint. Existing pedestrian routes, including those leading to school gates along the northern boundary, had to be maintained. Vehicle access was limited to a single entry point as required by the Highways Department.

DB3 were appointed as architects and masterplanners for RIBA Stages 1 to 4, including landscape design, to secure planning permission for the regeneration of the Culver site with a new residential development. The site consists of 173 dwellings (65% private sale and 35% affordable housing, including wheelchair accessible units), with public open space, play areas, car and cycle parking. New access roads, routes and footpaths also form part of the proposals.

Neighbouring properties’ amenity was considered early in the design. A sunlight and daylight specialist was consulted to prevent negative impacts, an approach highlighted in public consultations with local residents.

Maximising site use while safeguarding and improving the environment and ensuring a safe, healthy development were key objectives.

Achieving this balance required addressing conflicting factors, including high car parking requirements, policy standards on overlooking distances and garden sizes and specific space standards in the client’s brief. The biggest challenge was that nearly half the site was public open space. Reducing this while improving the overall quality of the public realm and landscaping was carefully considered.

Understanding the local character informed the scheme’s appearance, ensuring it complemented and enhanced the area. Following several site visits, actions included a constraints and opportunities review, urban analysis of the site and surroundings and assessment of key movements, links and connections. A thorough site understanding was fundamental.

Several category ‘A’ and ‘B’ trees were present on-site. Although a constraint, they informed the strategic landscaping. Two category ‘A’ oak trees in the centre provided a focal point and structured wider tree planting.

The site’s irregular shape, including mixed boundaries and approximately 1,000m of blank edges (rear garden fences and school playground fencing), required careful masterplanning. The layout integrated these into active street frontages and landscaped areas, avoiding dead space.

Stakeholder engagement was key to achieving high quality design. Early discussions with the Council’s Planning Department focused on reducing public open space while improving overall provision.

Meetings with the Highways, Urban Design and Landscape teams ensured alignment with policy.

Two public consultations gathered feedback from residents and local councillors, helping shape the final design.

Extensive research, site analysis, and stakeholder engagement informed the final scheme, ensuring it responded to local needs while delivering a well-designed, sustainable community.

ARGYLL AND BUTE COUNCIL

Helensburgh Waterfront Development Location: Helensburgh Expertise Area: Multidisciplinary Design Team Lead, Architecture and MEP Argyll and Bute Council set an outline business case to revitalise and regenerate Helensburgh’s waterfront. Subsequent masterplans were commissioned by Argyll and Bute Council to redevelop the picturesque waterfront of this coastal town.

To anchor the regeneration project the Council recognised that a new landmark community building would help increase footfall and enhance the town’s public spaces. The need for a modern, larger sports & leisure facility to replace the ageing swimming pool on the pierhead presented an opportunity to create a new leisure centre as a respectful piece of civic architecture that invites in the community, intrinsic to the future success of Helensburgh’s historic waterfront

With its emphasis on creating a building that feels open and connected to its surroundings, the design incorporates large windows for sea views and a layout that is easy to navigate. The materials chosen reflect the local environment, ensuring the building fits within the town’s historic context while offering a modern, functional space for the community.

Regeneration & Masterplanning

The new facility is designed to be a central point for both locals and visitors, encouraging participation in various physical activities, from swimming to fitness classes. The building aims to be accessible for people of all abilities, with features like wheelchair access to all pools and a user-friendly gym. It’s part of a wider initiative to improve public spaces, with nearby developments like Colquhoun Square and the promenade linking directly to this new landmark.

St Fagans Castle & National Museum of History Location: Cardiff, Glamorgan Expertise Area: Architecture, Conservation Architect & Passivhaus Design We are working on the regeneration of St Fagans Castle and its estate, working to restore and preserve this historical site for future generations.

Our approach has been centred on a balance between conservation and the integration of sustainable practices, ensuring the castle remains a vital part of the cultural landscape. Through essential repairs and modern upgrades, we are breathing new life into this significant landmark.

St Fagans Castle St Fagans Castle is a Grade I listed Elizabethan manor house, situated on the site of an old Norman motte and bailey castle. The current mansion house was built around 1580. In 1946, the castle, along with eighteen acres of land, was donated to the National Museum of Wales as the site for a national open air museum.

The castle has been statutorily recognised and protected in the highest category since 1977. Its courtyard features a Grade II* listed lead water cistern, while many garden structures hold Grade II status.

We are currently collaborating with National Museum Wales and the St Fagans estates team to carry out necessary maintenance and repairs to the listed building. The castle has suffered significant disrepair, with water damage and mould threatening both the integrity of the structure and its collections. As a result, the first floor has been temporarily closed to the public, with all collections removed, limiting visitor access to the ground floor. This situation has negatively impacted the visitor experience and restricted the building’s use for other revenue streams, such as filming and weddings, which previously took place at the castle.

Working closely with the conservation officer and Cadw, we have obtained approvals for a full reroofing of the castle. Additionally, we are undertaking extensive fabric repairs to restore the building to its former glory. We are working closely with specialists and surveyors to address issues such as condensation, dampness and mould.

St Fagans National Museum of History Open to the public since 1 July 1948, the Grade II listed museum stands in the grounds of the castle and gardens.

DB3 were appointed by National Museum Wales as Architects and Passivhaus consultants, up to RIBA stage 3, on the refurbishment of the administration building at St. Fagans National Museum of History.

Surveys were carried out that identified that the administration block required essential maintenance work. Prior to implementing any remedial work, the opportunity was taken by National Museum Wales to look at how different interventions could reduce carbon emissions.

Following on from this National Museum Wales received funding to explore Passivhaus retrofit (Enerphit) for this project. A fabric first approach has been taken during stage 3 to look at how Enerphit can best be achieved.

In the gardens, we are currently working on two Victorian glasshouses used for potting and propagation by the gardening team. The glasshouses feature their original Victorian glass, which requires careful restoration.

Additionally, the grounds include the House of the Future, constructed in 2000 as a showcase for cutting-edge green building technologies.

It was later repurposed as an education centre but required adaptions. We recently completed a reroofing project for this building.

Masterplan In the museum grounds, there are over 50 historic buildings from across Wales which have been rebuilt at the Museum including; a Victorian school, a medieval church and a Workmen’s Institute, chronicling the historical lifestyle, culture, and architecture of the Welsh people. As part of our work, we are looking at a masterplan to connect all elements of the facility together, creating a seamless visitor experience.

NATIONAL LIBRARY OF WALES

Estate Decarbonisation Location: Aberystwyth, Ceredigion Expertise Area: Architecture, Building Services Engineering DB3 Group were appointed as Lead Consultant, Architects and MEP Engineers for a Welsh Government backed decarbonisation project at the National Library of Wales.

The National Library of Wales, Aberystwyth is a Grade II* Listed Building which lies within a Grade II* Registered Historic Park and Garden.

The brief provided by the National Library of Wales required DB3 Group to investigate and design ways in which the National Library could significantly decrease its carbon footprint and also eliminate the use of fossil fuels on site by 2028.

The decarbonisation project designed by DB3 involves a multi-faceted approach which sees sustainable technologies, as well as renewable technologies, being introduced on the National Library’s site as well an extensive programme of fabric improvements.

The principal way in which it is proposed to bring about the elimination of fossil fuels on site is by the replacement of all the National Library’s 6 no. existing gas fired boilers by reversible air source and ground source heat pumps.

Two new external compounds are being provided for the air source heat pumps and the ground source heat pumps are being located in a field adjacent to Library’s site using 52nr 100m deep boreholes. A thermal response was undertaken during the design phase of our works.

The reversible heat pumps will cater for the heating as well as the cooling loads at the Library,

thus enabling all the existing chiller units as well as the 5MW of gas boilers to be removed from site.

The four plant rooms associated are being reengineered to facilitate the change over from gas whilst the general building heating systems will remain.

Given the historical significance of the building, our architecture team worked to secure various consents, including planning permission for air source and ground source heat pumps, roof mounted solar panels and ground mounted solar panels in adjacent fields. Fabric improvements were key elements of the project. In Book Stack 2, the existing timber windows were repaired, and secondary glazing was installed, while in Book Stack 3, the original 40 year old aluminium windows were replaced with double-glazed units. Reroofing and insulation upgrades were undertaken to prepare for solar panel installations. This work required careful sequencing to minimise disruption, with localised closures and tented structures used to protect the live site.

The project’s complexity was compounded by several factors. Storm Darragh caused unforeseen damage to the temporary tent structures, necessitating adaptive solutions.

Managing multiple contractors while addressing spending pressures has required meticulous coordination, as fabric repairs, M&E upgrades, and other interventions have been carried out simultaneously.

Two schools are being combined into a single site, to form a new English language Church of England school. Another school is undergoing extensive fabric repairs, while a brand new Welsh language primary school will support the growing number of pupils wanting Welsh-medium education.

With several of the buildings being Grade II listed, all work follows heritage guidelines. This means carrying out detailed heritage impact assessments, securing listed building consent and working

closely with conservation officers. Repairs to historic structures, including the old boathouse at one site, will ensure these buildings are no longer left unused and deteriorating. By restoring the boathouse - previously derelict for 30 years - it can become a valuable space for the school and wider community, potentially being used for after school clubs and learning activities.

The work schedule is carefully planned to minimise disruption, with construction happening mainly during school holidays. A long term programme of repairs will ensure that the buildings are not only functional but also preserved for future generations.

CAERPHILLY COUNCIL

Ty Du Business Units Location: Nelson, Caerphilly Expertise Area: Multidisciplinary Lead & Architecture

Bringing modern, flexible workspaces to Nelson, encourages investment in the area, revitalising the local economy and providing employment opportunities.

The newly created floor areas were approximately 20,000sqft in size. The Ty Du site already had existing outline planning permission and the aim was to design modern highly efficient business starter units for the employment parcel of the land and submit to planning for approval of reserved matters within the required time scales.

The team worked with Caerphilly Council and their commercial property advisers to review site layout options and then to develop designs for high

quality flexible units that satisfy the requirements of the Council and the local market. The prominent scheme was partly Welsh Government and European Union funded and was developed to BIM Level 2, to achieve BREEAM 2018 Excellent.

The project was designed to include five buildings, each of which can be subdivided into two or three units. The external envelope of the buildings has been designed to be highly thermally efficient whilst remaining attractive and flexible enough to provide an internal environment that can be used for B1 industrial or B1 office uses. IES thermal modelling was used to inform the thermal properties of the fabric, including U and G values ensuring that the buildings achieve their energy targets.

As this site was part of a wider masterplan, we discussed the Ty Du scheme in detail with the Local Planning Authority and the typology and materials chosen were carefully considered along

DB3 were appointed via the NPS Framework by Caerphilly Council to lead and manage a multi– disciplinary team to develop designs for flexible use B1 employment units on the Ty Du site in Nelson.

NATIONAL MUSEUM WALES AMGUEDDFA CYMRU

Big Pit National Coal Museum Location: Blaenavon, Torfaen Expertise Area: Architecture, Conservation Architect

A number of buildings have a protected status.

The Powder House, Saw mill, office and the Electrical Workshop, have Grade II listed building status. The Pit Head Building, Headframe & Tram Circuit and the Miners’ Bathhouse have Grade II* listed building status.

In our role as architects, we have several ongoing projects at the museum focusing on repair and enhancement to the existing buildings.

A Grade II Listed building, The Pithead Baths houses four exhibition spaces and uses objects and images to tell the story of coal mining in Wales. There is also a multifunctional space serving as an education room, canteen and lecture theatre, housing both temporary and permanent exhibitions. However, the building is currently in a state of deterioration.

As architects, we are leading a sensitive retrofit project, focusing on fabric repairs and essential upgrades to preserve its historical integrity while ensuring it meets modern functional needs. Aligned with National Museum Wales’ decarbonisation efforts, a ground source heat pump has been installed to improve energy efficiency, along with double glazing and roof insulation.

The Fan House, located at the rear of the site, is one of the most important buildings in any coal mine. Its ventilation system plays a crucial role in bringing oxygen into the mine, removing or diluting unwanted gases, dust, and fumes and maintaining a cooler, drier environment.

As an underground experience is available to all visitors, the Fan House remains fully operational today. However, we are currently reviewing the replacement of the existing fan systems, as they are outdated and require frequent cleaning due to black mould buildup. Cleaning the fans often results in temporary mine closures, which negatively impact the visitor experience.

The Tram Shed, once vital for transporting coal to and from the mine, is at risk of collapse. To preserve its legacy, we have been working closely with structural engineers to stabilise the structure.

As part of this effort, we are implementing temporary support works.

Regeneration & Masterplanning

As a vital regeneration project within the unique Blaenafon Industrial Landscape, a designated UNESCO World Heritage Site, our work at Big Pit plays a crucial role in preserving and enhancing Wales’ rich coal mining heritage. Once employing up to 1,300 workers, Big Pit has now transformed into an interactive museum dedicated to the operational preservation of this industrial legacy.

Through careful restoration and modernisation, we are ensuring that this historic site continues to educate and inspire future generations.

NATIONAL MUSEUM WALES AMGUEDDFA CYMRU

The National Slate Museum Location: Llanberis, Gwynedd Expertise Area: Client Advisor The National Slate Museum, previously known as the Welsh Slate Museum and the North Wales Quarrying Museum, is located at Gilfach Ddu, within Padarn Country Park in Llanberis, Gwynedd. The museum sits in the 19th century workshops of the once operational Dinorwic Quarry and is dedicated to preserving and showcasing the history of Wales’ slate industry.

As an anchor point on the European Route of Industrial Heritage (ERIH) and part of National Museum Wales, the museum plays a key role in telling the story of the region’s industrial past. The workshops were built in 1870 on land created from spoil from the nearby Vivian Quarry.

This redevelopment is a prime example of regenerative development. It preserves the site’s heritage while making it more accessible and relevant for the future. The restoration of the Grade I Listed building, the reconfiguration of existing structures, and the addition of new facilities, like a learning centre, shop and café, will ensure the museum’s long term success. The project also focuses on sustainability, accessibility, and community engagement, bringing new opportunities to the local area while highlighting the cultural importance of Wales’s slate industry.

The redevelopment involves essential repairs to the Grade I building, partial demolition of later additions, reworking a Listed office block, improving disability access, and creating new visitor spaces.

As Client Advisor, we have worked closely with the client throughout the process, supporting tasks like the temporary relocation of 8,000 artefacts to a secure site. Our experience in regeneration and conservation has been vital to ensuring the project’s success, guiding the client every step of the way.

Regeneration & Masterplanning

After the quarry closed in 1969, the site was transformed into a museum. Today, a £21 million redevelopment project is underway to secure the future of the museum and its collections. With support from Cyngor Gwynedd, the Welsh and UK governments, and the National Lottery Heritage Fund, the museum will become a key site for interpreting the Slate Landscape of Northwest Wales UNESCO World Heritage Site.

LEEDS CITY COLLEGE

Printworks Campus Location: Leeds, West Yorkshire Expertise Area: Architecture

DB3’s expertise spanned RIBA Stages 1 to 6, ensuring a fully coordinated approach that brought together the design team, client and modular system fabricator. The result was a bespoke building that not only meets the needs of its users but also aligns with the regeneration efforts shaping the area.

The DB3 team conducted extensive end user engagement workshops to ensure that the design met the needs of the college and the teaching delivery team. This process was coordinated with the planning, transport and environmental consultant teams, as well as the manufacturing client team, to ensure that the final design met all relevant requirements. Throughout the build process, the college engaged the students and took them on visits to see the modules being installed as well as the detailed fit-out works.

The design features partially perforated corten steel cladding and a double height glazed entrance. This bold and distinctive architectural intervention aims to provide a unified space for the technology students who will be utilising the building.

The completed building is highly sustainable, achieving a BREEAM ‘Very Good’ certification’. The design began with a built off-site prefabricated

system that promotes net zero waste to landfill, fabricated by Premier Modular. With a total GIA of more than 1,120m², the building was on site for just six months due to its off-site construction system. The creation of the new building posed a number of challenges, particularly with regard to protecting the neighbouring Grade II listed building. In addition, the prefabricated construction system utilised in the project required strong technical coordination throughout all design stages. DB3 successfully addressed this challenge by engaging the client early on in the process, ensuring that all aspects of the project were fully coordinated and executed with precision.

The final result is a fully bespoke building, which not only meets the brief but also responds to its locale and the teaching it is meant to house.

DB3 has since been commissioned to carry out a secondary MMC project for the college after the successful delivery of the Printworks Campus.

“The new building will play a vital role in giving students the best possible learning experiences and opportunities. It’s a beautiful building and it’s wonderful that it’s been built with sustainability in mind.”

The Right Honourable Hilary Benn, Leeds Central MP

Regeneration & Masterplanning
