The demolition of a 1970s brutalist housing estate in London’s Southwark created a 28 acre regeneration site, vacant except for a number of beautiful mature trees. These trees form the core of Elephant Park, a new green space at the centre of a new mixed use quarter. The final building plot in the masterplan has been set aside to create a workplace of the future, on the doorstep of Elephant Park.

Active Ground Plane

New office buildings should be low carbon, embracing landscape and outside spaces on every level with simple, low-tech building services that will age well and allow for future change. In order to provide south-facing outdoor gardens at every level, the H1 building has been shaped as a steeply terraced volume. A shared ground floor space accommodates an open lobby, cafes, affordable workshops and event spaces - blurring the edges of foyer and landscaped park.

The 17 storey structure of the building is designed as a hybrid timber-steel frame. Sizing of the structural components and a sprinkler system allow timber beams and slabs to remain exposed safely, creating a contemporary timber warehouse of the future. The hybrid timber-steel frame, shading facade, green terraces and highly optimised building services are creating a 21st century green building with minimum carbon in construction and zero carbon in use.
