Commercial Building Award

Holbein Gardens by Barr Gazetas

This project was driven by a desire to create London's most sustainable office building, one that allows people to thrive whilst providing best in class workspace, biodiversity and new technologies. Kirsten Lees of Grimshaw on the judging panel said “This is a fantastic case study that can help show the way to how more of our existing building stock can be retained and refurbished with excellent sustainable outcomes even when the original building itself needs to be demolished. Research used here can be harnessed and used across the industry and help promote more and better material re-use.”

Public Building Award

Biophilic school De Verwondering by ORGA architect

A primary school seeking to reconnect young people to nature through its presence in architecture, interior design, and landscape. Judge Thorsten Nölle of ARGE BB07 said: “The project is an excellent example of building with nature and ground-breaking for future school buildings and new inspiring learning landscapes.”

Residential Building Award

The Sköndal Villa by Liljewall arkitekter

The vision for this inspiring project was to not only climate-neutral, but also beautiful, functional and at the same time financially sustainable. Judge Stephanie Crombie of Morrow + Lorraine Architects and ACAN said the project was “An impressive example of low-energy nursing home focusing around low-embodied and operational energy in tandem with high-quality later living. Recycled elements incorporated throughout, including recycled brick facades, aluminium and glass wool insulation”.

Product & Materials Initiative Award

Secondary timber in laminated structural elements by Simple Works

Through an ongoing collaboration between Simple Works and UK CLT a new product initiative has been developed to turn waste timber into usable structural elements. Judge Hans Hammink of de Architekten Cie said “This is what we need. Used materials upgraded into new CLT elements. A constant supply stream meets the demands of the building industry. This will lessen the need for new material.”
