Frequently Asked Questions — Hillingdon Architects
Is my property in a conservation area in Hillingdon?
Hillingdon has designated conservation areas including Black Jacks Lock, Copper Mill Lock, Cowley Lock and others. Within these areas certain permitted development rights are restricted, so some external alterations that would be permitted elsewhere may need full planning permission supported by design and heritage justification. We confirm your property's designation with London Borough of Hillingdon at the outset and prepare the documents these applications require.
How long does planning permission take?
Most householder planning applications are determined within the statutory 8-week target; more complex or conservation-area applications can take longer. We manage the whole process and liaise directly with the planning officer on your behalf.
