Westminster, around Parliament, means Georgian terraces and mansion blocks near the river. Nearly every home is an apartment. Many are leasehold.

Architecture here is mostly interior architecture. Walls move, rooms combine and services are rerouted. The outside rarely changes.

Where an extension happens, it is usually lateral, across a floor. Flats have no householder permitted development rights, so consent is needed.

Close to the Thames, flood zones 2 and 3 need a site specific assessment. We check the address first.

Our nearest project is a 1,500 sq ft SW1 apartment, designed and fitted out. Another sits nearby in Belgravia.
