The winners of the Building Awards were announced at a ceremony on Tuesday night. Here is more detail about all the winning entries


CEO of the Year 

Mark Reynolds of Mace

DGP logo NEW

There is no denying it has been a successful year for Mace chief Mark Reynolds. The firm’s consultant arm has continued to expand – recording a 36% jump in income to £500m last year. It has also continued to grow its overseas operations, with strong contributions from the European and Middle Eastern markets.

On top of this, in July Reynolds announced Mace planned to be a 10,000-strong business by 2026, seeking 2,500 new staff over the next three years. He said it expects to take on 1,000 people this year, numbers already up to 7,800 from 2022’s year-end figure of 7,300 and up 19% on the 6,652 employed in 2021.

Another focus for Mace under Reynolds’ leadership has been evolving the business culture. This included welcoming the most diverse group of undergraduates yet, in part due to its support of the 10,000 Black Interns programme. The year also saw a 21% rise in women working in Mace’s construction business.

Major project highlights this year included the completion of the much-lauded Battersea Power Station project – which has been recognised as one of the world’s most technically challenging schemes.

On top of this, Reynolds has been batting for the industry as a whole in his role as Construction Leadership Council co-chair. The CLC’s work this year has included launching a pilot project on a scheme developed by the contractors’ umbrella body ActuateUK to tackle project defects at source, research into the sector’s productivity, and a consultation on its biodiversity roadmap.

Housing Project of the Year

Winner: Dockley Apartments

Entered by Studio Woodroffe Papa / Poggi Architecture

Housing Forum

Dockley Apartments transforms a former industrial site in London’s Bermondsey into a vibrant city block. Legendre was construction partner on the scheme. 

Key passive design features include a high-performance building fabric, airtightness and thermal bridging to reduce winter heat loss and lower energy use for space heating.

The use of radiant heat technology reduces lifecycle carbon use and counters rising fuel costs for residents.

International Project of the Year

Winner: New Administration Building, Mae Ramat

Entered by Bidwells

This project comprised the design and delivery of a new administration building in rural Mae Ramat, Thailand, alongside a lab fit-out on the ground floor of a local hospital, funded by the University of Oxford’s Nuffield Department of Medicine and by the Wellcome Trust.

The scheme was delivered for the Borderland Health Foundation, which focuses on malaria, tuberculosis, and maternal and child health.

The university led the supplier selection process, which saw Bidwells named as project manager. The client brief evolved over the course of the project. After the initial design was created, Bidwells was given the design, which was further developed by a Thai multidisciplinary architect to translate and deliver it.

As a result, the location of the development was moved from a town to a rural location on the outskirts, and the design was modified to make the most of the new location and create an optimal finished product.

Client of the Year

Bournemouth, Christchurch and Poole Council

To tackle a huge beach littering problem, the council worked with WSP to create the Durley Chine Environmental Hub, which helps the area’s residents and visitors understand the environmental impact of single-use packaging and waste on the region’s fragile coasts and sea. The hub also acts as a sustainability exemplar itself, as it uses a high proportion of recycled, reclaimed and renewable materials.

Retrofit/Refurbishment Project of the Year

Quadrangle Building, King’s College London

Entered by Hall McKnight


Hall McKnight’s project brings a building that occupies an unusual, constrained space back into use as a home for the university’s engineering department.

Situated within a grade I-listed site in The Strand conservation area, the building’s roof forms the quadrangle of the founding campus.

The undergraduate learning and teaching spaces are designed to encourage collaboration and interaction.

Offsite Project of the Year

National Manufacturing Institute Scotland 

Entered by HLM Architects

The new NMIS, rated BREEAM Outstanding, supports Scottish manufacturing businesses by helping attract investment and providing connections to engineering universities and colleges.

Standardisation was considered throughout by way of repetitive grids and modules, enabling economies of scale and a reduction of material wastage by using repetitive design sections.

Offsite manufacture was also critical to realising the project’s ambitious delivery programme.

Housebuilder of the Year

Berkeley Group


In the last year Berkeley Group has continued to focus on brownfield regeneration, reviving underused land to create unique, sustainable and nature-rich places where communities thrive. The firm has delivered 86% of its homes on brownfield land and built more than 4,600 mixed-tenure homes in the last year alone.

According to the Home Builders Federation, Berkeley had a net promoter score of 79.2+, against an industry average of 42. In addition, 97.5% of its customers would recommend the firm to a friend, compared with an industry average of 90%.

Current schemes include the 2,500-home White City Living (pictured), in west London.

Berkeley Group has 54 net biodiversity gain strategies in place, to deliver more than 550 acres of new or measurably improved habitat. In March of this year it co‑hosted the Biodiversity Net Gain Conference in partnership with Natural England and the Local Government Association, in order to share best practice.

The firm says 97.5% of its sites incorporate wetland features, with 52 acres of wetland habitat planned or completed. Its Royal Exchange development in Kingston achieved water neutrality in a trial completed with Thames Water, which involved retrofitting and upgrading 79 local businesses, homes and schools to save 45,00 litres of water.

This year Berkeley achieved its 2030 science-based targets for scope one and two emissions, having seen a 56% reduction compared with 2022 and a 76% reduction since its 2019 base year.

Berkeley has invested £560m in the communities in and around its sites in the past year, through affordable housing subsidies as well as wider community and infrastructure contributions.

The firm says 100% of its regeneration sites with residents have community plans in place, and it has actively engaged with the industry-wide Future Homes Hub and the Nature and Places Steering Group, as well as the Quality of Life Foundation.

The past year was also a breakthrough year for Berkeley’s social impact programmes. It scaled up partnerships and invested £3.9m into 50 charities supporting 13,000 disadvantaged people in local communities. Meanwhile, 59% of its employees contributed to the Berkeley Foundation in the past year.

Grenfell Nursery

Entered by Perkins&Will

This is a new home for the Grenfell Early Years Nursery, a cornerstone of the Lancaster West Children’s Community Network in north Kensington.

Originally housed at the foot of Grenfell Tower, following the tragedy of 2017 it moved to temporary accommodation before having its new home developed.

Siderise has created an extensive technical and service wrapper around its high-performance, third-party tested cavity barriers and fire stops, to support best-practice specification and installation. Conversations with customers highlighted that using stainless steel cavity trays to meet new Building Regulations was time-consuming and expensive, with installation often difficult.

In response, it developed a market-disrupting solution that combines an aluminium tray and insulation in one engineered product that can be installed eight times faster than traditional approaches.

Major Contractor of the Year (over £500m)

The past year has been a shining one for Mace. The firm’s construction business began the year with 73% of its budgeted turnover secured and ended it having converted over £2bn-worth of new work. This is the equivalent of one project win a week and puts the business firmly among the top echelon of London contractors. It also completed one of the world’s most challenging projects at Battersea Power Station (pictured), broke into new markets, and had its best health and safety performance ever, reaching an accident frequency rate of 0.03, all while tackling the biggest challenges facing the sector.

Embedding practices and tools to manage risk and behaviours, simplifying processes and implementing intelligent data solutions all led Mace to a consistent culture of health, safety and wellbeing excellence that produced exemplary results last year. The firm took a proactive approach to seeking out risks, sharing learning and campaigning for safer behaviours. This resulted in a reduction in the number of reportable incidents from 25 to eight year-on-year.

Sustainability has also been a focus, with Mace entering its third year as a carbon-neutral business, having further reduced its emissions and offset those remaining via Gold Standard offsets. It became a founding member of ConcreteZero, reaffirming the firm’s commitment to delivering low-carbon concrete, and continued to test and develop its pioneering low-carbon cassettes, securing their installation on two sites in early 2023. Mace delivered its first ever diesel-free site at 78 St James Street and introduced a ban on diesel generators for all its construction projects, opting for electric plant and accredited HVO fuel as alternatives.

Another focus has been the support the firm gives through development and tools to set its people up for success. Mace continued to invest in talent and increased the number of graduates and apprentices by 197, which in total made up 5.3% of its workforce. This included welcoming the most diverse group of undergraduates to have joined Mace yet, in part due to its support of the 10,000 Black Interns programme. The year also saw a 21% increase in the number of women working in Mace’s construction business.

Contractor of the Year (up to £500m)


Last year saw Britcon return to the black after a loss-making 2021 due to a volatile trading environment. A buoyant market with skills shortages also caused higher-than-normal employee churn. In response, it introduced a new senior management team focused on growing the business and introducing strategies to address key challenges and improve resilience.

Successfully returning the company to profit while retaining and attracting people from diverse backgrounds has been a cornerstone of the past 12 months.

Britcon has invested over £1m in people, technologies and partnerships to respond to industry challenges, including decarbonising its operations, improving health, safety and wellbeing, embracing digital technologies and implementing MMC and whole-life efficiencies. The positive impacts of these changes include the firm’s digital snagging process reducing defects by 26%.

Britcon has also expanded its operations geographically with work for ABP in East Anglia and a clean energy hub for Redcar and Cleveland council.

Battersea Power Station Phase II

Entered by Mace


Bringing the mighty power station back to life after closure in 1983 has been one of Britain’s biggest and most challenging projects.

The four distinctive chimneys were demolished and carefully rebuilt to match the originals, with nearly 1.8 million bricks specially made.

The turbine halls have been reinvented as retail spaces, the old boiler house as offices and the switch houses as flats.

At the project’s peak there were 17 cranes and 3,000 workers on site.
