Planning in Hillingdon
Local planning rules for new build homes in Hillingdon.
Hillingdon's conservation areas include Ruislip Village, Eastcote Village, Harefield, Ickenham Old Village, Cowley Lock and parts of Northwood. Green Belt and the Colne Valley restrict new development on the western fringe. Outside heritage zones, the borough is planning-friendly with strong PD rights — hip-to-gable lofts, dormers and 6m rear extensions are routinely approved. Two-storey side extensions on the prevailing semi stock are commonly approved with the 1m first-floor setback. The council favours traditional brick and clay tile on extensions matching original stock.
Our planning team handles the full submission for Hillingdon addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your new build home is permitted development, prior approval, or full planning before you sign anything.
