Side-return extension in Vauxhall

A family in Vauxhall approached us for side-return extension on a regency terraces property. Constraints: respecting streetscape rhythm typical of Lambeth, maintaining rear garden depth, and meeting Lambeth Council's design expectations for the conservation context (64 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 Lambeth Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.

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