Does UB8 planning policy restrict a drawing package?

UB8 (Uxbridge / Cowley) conservation designations: there are 29 across Hillingdon Council, Uxbridge, Ruislip Village, Northwood among them. Designation costs a UB8 (Uxbridge / Cowley) 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. Harefield is the UB8 (Uxbridge / Cowley) designation that most often changes a drawing package design.

Article 4 and your UB8 (Uxbridge / Cowley) drawing package: Hillingdon Council has made no borough-wide direction, so permitted development for a drawing package in UB8 (Uxbridge / Cowley) generally survives outside UB8 (Uxbridge / Cowley) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a UB8 owner records that a drawing package was lawful.

UB8 (Uxbridge / Cowley) housing stock: 1930s semi-detached dominates; Metropolitan Green Belt covers much of north Hillingdon; Victorian cottages in Uxbridge and Ruislip villages; post-war housing near Heathrow.

Which neighbouring authorities border UB8?

• Harrow — the Harrow boundary runs against Hillingdon, so a drawing package a street from UB8 (Uxbridge / Cowley) is decided by Harrow Council instead. Harrow runs 29 conservation areas across HA1 and its neighbours, which is why architectural drawings priced for UB8 (Uxbridge / Cowley) are re-checked against Harrow policy whenever the UB8 (Uxbridge / Cowley) address sits on that edge.
• Ealing — adjoining UB8 (Uxbridge / Cowley), with 30 conservation areas centred on W3. A drawing package on the far side of the UB8 (Uxbridge / Cowley) line is determined by Ealing Council, so the UB8 (Uxbridge / Cowley) quote for architectural drawings is checked against Ealing guidance before it is issued.
• Hounslow — cross the UB8 (Uxbridge / Cowley) boundary and Hounslow Council takes the drawing package instead, applying 30 conservation areas of its own around W3. We re-price architectural drawings at the UB8 (Uxbridge / Cowley) edge because Hounslow policy and Hillingdon policy rarely align on drawing package depth.
