Earl’s Court rises in tall stucco terraces and red brick mansion blocks. Most houses hold several flats.

The usual brief is a lower ground garden flat. Its kitchen pushes out under a glass roof, toward the garden.

A few owners want to reunite flats as houses. Policy HO1 resists merging self-contained homes, so feasibility starts there.

Big terraced houses that stayed whole can take a full width rear room. CD13 keeps it below the eaves.

Fronts are protected too. In Philbeach, even repainting a front needs planning.
