What local planning policy applies to a drawing package in UB7?

UB7 (West Drayton / Sipson / Harmondsworth) conservation designations: there are 29 across Hillingdon Council, Ickenham, Uxbridge, Ruislip Village among them. Designation costs a UB7 (West Drayton / Sipson / Harmondsworth) owner the permitted-development route: a drawing package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Ruislip Village is the UB7 (West Drayton / Sipson / Harmondsworth) designation that most often changes a drawing package design.

No blanket Article 4 over UB7 (West Drayton / Sipson / Harmondsworth): Hillingdon Council has not withdrawn permitted development across UB7 (West Drayton / Sipson / Harmondsworth), so a drawing package outside a UB7 (West Drayton / Sipson / Harmondsworth) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a UB7 owner wants on file.

The building fabric around UB7 (West Drayton / Sipson / Harmondsworth): 1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near Heathrow. Largest outer west London borough; significant Green Belt; Heathrow noise contours affect planning decisions in Harmondsworth and Sipson. A drawing package in UB7 (West Drayton / Sipson / Harmondsworth) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Hillingdon Council.
