Westminster
One Berkeley Estate is the redevelopment of an existing 1970s RC frame for hotel and office use. Generally the existing structure is demolished to level seven, and a new two-storey rooftop extension installed. There are also side extensions into Dover Yard to the rear, plus a new annex building.
Key features
· Extensive archive searches and intrusive investigations to understand the capacity of the existing building
· Justifying existing superstructure and raft foundation for increased loads with minimal strengthening works
· Satisfying ground movement constraints imposed on the development by underlying London Underground service tunnels
· Detailed assessment of the existing and proposed building stability to minimise proposed interventions
· The service yard at ground floor level will be transformed into a green and biodiverse public realm
· Temporary works design for global stability, basement walls and retaining a boundary wall adjacent to 40 Dover Street
One Berkeley Square comprises the redevelopment of an existing eight-storey post-war office block and hotel front Piccadilly.
