Bryanston Square

In converting this site in a historic Georgian Square from a hospital to apartments, we tried to retain as much of the existing structure as possible.

However the façade was so decayed that it was rebuilt as a facsimile of the original, and although reusing the existing foundation piles was technically feasible, it proved hard to find a contractor who would give a warranty on them. Consequently we had to devise an entirely new structure and the key to it is an 800 mm-deep transfer slab at ground floor level. This means there can be two different grids for reinforced concrete frames: the larger one below ground for car parking with a smaller grid for the residential units above, and we use the cores rather than any additional insertions to give overall lateral stability.
