Awards
Celebrating our Net Zero Architect of the Year win
by AHR
We’re proud to have been named Net Zero Architect of the Year at this year’s Building Design Architect of the Year Awards, recognising our commitment to designing and delivering sustainable, future-focused buildings that support climate action, community wellbeing and long-term resilience across sectors.
Our win demonstrates the holistic approach we take to net zero design, creating efficient, innovative buildings that perform and adapt. From education and healthcare to residential and mixed use innovation districts that blend research, enterprise and flexible workspace, we’re shaping a built environment that supports long-term sustainability and wellbeing. The four projects in our submission embody this approach, each a tangible example of how design excellence, collaboration and technical advancements can drive measurable progress towards net zero, set new benchmarks and deliver enduring value across sectors.
A new standard for energy-efficient, net zero carbon healthcare facilities
At the Countess of Chester Hospital, our new Women and Children’s Unit is the first NHS building in England approved under the Net Zero Carbon Building Standard. Replacing outdated RAAC infrastructure, the design exemplifies how net zero healthcare design can enhance both sustainability and human experience, delivering a high-performing building that supports the wellbeing of patients, their families and staff.
Addressing fuel poverty and enhancing resilience
A town-centre Passivhaus Classic development, 1–21 St Cuthberts, offers 20 all-electric homes for assisted living and over-55s. This project demonstrates how net zero housing can be both affordable and life-enhancing, enabling residents to live safe, healthy and independent lives within the community.
A most impressive range of projects, all displaying a high degree of design excellence and integrity. This was combined with exemplary rigour in the targeting and measurement of embodied carbon and energy performance in the submission. Working with difficult sectors and government backed projects, and delivering net zero is an achievement in itself.”

'Net zero design’ means creating buildings that minimise carbon emissions throughout their life cycle both in construction (embodied carbon) and operation (energy use). Through fabric-first design, efficient systems, and renewable technologies, our projects achieve exceptional performance while promoting occupant wellbeing.
Winning BD’s Net Zero Architect of the Year affirms our leadership in sustainable architecture and our commitment to shaping a built environment that supports climate action, community wellbeing, and long-term resilience.
