Basement extension under garden in Earl's Court

A family in Earl's Court approached us for basement extension under garden on a stucco terraces property. Constraints: respecting streetscape rhythm typical of Kensington and Chelsea, maintaining rear garden depth, and meeting RBKC Planning's design expectations for the conservation context (38 conservation areas borough-wide).

Measured survey week 1. Three design iterations balancing internal layout against external massing visible from neighbours. Two scheme massings tested against RBKC Planning's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.

Submitted to RBKC Planning via the Planning Portal. With Article 4 in force in Kensington and Chelsea, we confirmed our scheme retained the necessary permissions before submission. Officer comments minor, addressed in 5 days. Approved with conditions.
