Our award-winning projects are as follows:

Building Performance Champion and Project of the Year (Retrofit Workspaces): The Entopia Building

A man and a woman chat in a large communal room with a table and groups of seats.

Architect: Architype / Feilden+Mawson

Client: Cambridge Institute for Sustainability Leadership

The judges described the whole life-building performance of Entopia as exceptional. Despite, what they called, an 'incredibly robust and challenging brief', the winning team had delivered an exemplary retrofit of a 1930s telephone exchange that had levels of performance comparable with a brand-new office building.

The Entopia retrofit shows that, with ingenuity and collaboration, it is possible to deliver healthy, high-performance buildings on a typical refurbishment budget.

The judges called the project a trailblazer for large commercial buildings moving to net zero.

“[The Entopia Building is] a great example for others to learn from.

A huge amount has gone into delivering this retrofit.”

Project of the Year (Residential): Agar Grove Estate Phase 1b

Living room with staircase to second floor, featuring furniture and natural light

Architect: Mae / Architype

Client: Camden Council

In a highly competitive field, the judges hailed Agar Grove 1b's exemplary application of design best practice on a large scale. They praised Max Fordham's comprehensive focus on building performance and its steadfast commitment to serving the local community.

The project marks the second phase of one of the largest Passivhaus housing schemes in the UK, compromising 34 council-owned and 23 private homes. Max Fordham adopted a passive-first approach to M&E design, prioritising minimal heat less and energy use.

The judges said it was important to recognise Agar Grove 1b as a trailblazer for large, complex housing projects.
