Approved in conservation area by Southwark Council in 16 weeks. Fixed fee £1,575.
A family in Nunhead approached us for mansard roof extension on a victorian terraces property. Constraints: respecting streetscape rhythm typical of Southwark, maintaining rear garden depth, and meeting Southwark Council's design expectations for the conservation context (43 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 Southwark Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.
Submitted to Southwark Council via the Planning Portal. With Article 4 in force in Southwark, we confirmed our scheme retained the necessary permissions before submission. Officer comments minor, addressed in 5 days. Approved in conservation area.
