Architect Allford Hall Monaghan Morris reimagined two 1970s Mayfair buildings into a 19,500m² mixed-use development. The project retained 81% of the original structures, significantly reducing carbon emissions.

The team integrated new cores and lifts into existing frameworks, optimised basement spaces and introduced a pavilion, annex office and public courtyard. Sustainable features include mixed-mode ventilation and reclaimed materials. The development enhanced the urban fabric by transforming Dover Yard into a pedestrian-friendly space. This project exemplifies AHMM’s commitment to innovative, environmentally conscious urban regeneration.

An ambitious retrofit in London’s Victoria has transformed a tired 1950s structure into a net-zero workplace of the future. The £135m redevelopment provides 109,000ft2 of grade A office space, 14,000ft2 of communal areas, and best-in-class amenities.

Half of the site consists of external landscaped areas, a rarity in urban settings. The project extended the building’s life by over a decade, while retaining 35% of the existing structure. The development also prioritises occupant wellbeing and smart technology integration.
