A family in Wealdstone approached us for mansard roof extension on a 1930s semi-detached property. Constraints: respecting streetscape rhythm typical of Harrow, maintaining rear garden depth, and meeting Harrow Council's design expectations for the conservation context (29 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 Harrow Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.
Submitted to Harrow Council via the Planning Portal. Permitted Development eligibility confirmed via parallel LDC. Officer comments minor, addressed in 5 days. Approved in conservation area.
