Mill Yard Pavilion, Cambridge
Client: Socius
Role: Competitions Adviser
S Williams Architects was appointed by Socius to act as Client Adviser and Chair of the design competition for a new pavilion building, a key focal point within their ambitious mixed-use development in Cambridge.
Set within a newly created green park, the pavilion will become a central gathering place—bringing nature back into the heart of the city. This vibrant landscape will improve local biodiversity, support sustainable drainage, and offer inclusive, welcoming spaces for community use and enjoyment.
The pavilion is part of a wider masterplan to transform the site into a thriving, mixed-use neighbourhood. The scheme includes high-quality homes, generous public realm, flexible office space, and a variety of community-focused amenities.
Working closely with Socius, Sarah Williams led the development of the project brief, grounded in the vision to create a meaningful civic asset. The design objectives included:
Creating a central covered space for year-round events, gatherings, and community use
Designing a structure that sits harmoniously within its surroundings and enhances the architectural identity of the wider development
Ensuring that every aspect of the pavilion—from materials to construction—reflects the project's strong environmental values and commitment to sustainability
Following an open international design competition that attracted over 40 entries, five outstanding practices were shortlisted. George King Architects was ultimately selected for their innovative and inspiring response.
Their winning proposal, the ‘Three Trees Pavilion’, blends architecture, art, and nature to create a striking and sustainable landmark. Described by George King as “a testament to our dedication to environmental stewardship,” the pavilion aspires to achieve carbon neutrality throughout both its construction and operation.
This landmark project reflects a shared commitment to community, design excellence, and climate-conscious development, setting a new benchmark for future urban public spaces.
