Basement extension under garden in Park Royal

A family in Park Royal approached us for basement extension under garden on a modern apartments property. Constraints: respecting streetscape rhythm typical of Ealing, maintaining rear garden depth, and meeting Ealing Council's design expectations for the conservation context (30 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 Ealing Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.

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