The Boiler House
The six storey building is constructed on an in situ reinforced concrete 600mm deep raft foundation and includes a first floor transfer slab. A total of 54 studio, one-bed and two-bed apartments are accommodated, with two commercial/retail units at ground level and a shared roof garden. The CLT structure uses sustainably sourced timber, and is clad in stainless steel shingles. Many of the apartments include balconies.
Whitby Wood is responsible for the geotechnical and civil engineering, as well the structural design. Our client was first the specialist developer Hub Group, then Henry Construction, which is the main contractor. Concept design is by architect Studio Egret West. To realise the design intent, a special finish ‘white’ concrete has been incorporated into exposed columns at ground level and the first floor slab soffit above the entrance lobby.
We were able to find substantial cost savings for our client and reduce the programme length by several weeks through our geotechnical expertise and design capabilities. The original foundation specified was a piled solution, which we demonstrated could be effectively replaced with the concrete raft.
