A Knightsbridge address can fall under either of two planning authorities. Policies, officers and tests all change at that boundary.

So our survey starts with a map, not a tape measure. Only then do we test the brief.

Grand stucco terraces and mansion blocks hold most homes. A handful of townhouses stand closer to the park.

A lateral apartment here began, for us, as a set of architectural drawings. It became a 2,500 sq ft home, finished in 2019.

Vaults run under some pavements here. Work beneath the highway is capped in depth.
