Approved at first submission by Hillingdon Council in 12 weeks. Fixed fee £1,395.
A family in Hayes approached us for hip-to-gable + dormer loft on a 1930s semi-detached property. Constraints: respecting streetscape rhythm typical of Hillingdon, maintaining rear garden depth, and meeting Hillingdon 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 Hillingdon Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.
Submitted to Hillingdon Council via the Planning Portal. Permitted Development eligibility confirmed via parallel LDC. Officer comments minor, addressed in 5 days. Approved at first submission.
