What local planning policy applies to a drawing package in DA17?

Conservation areas covering DA17 (Belvedere): Bexley Council runs 16, and Bexley Village, Old Bexley, Crayford are the ones DA17 (Belvedere) owners meet most. A drawing package inside a DA17 (Belvedere) conservation area loses permitted development, so the DA17 (Belvedere) submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Welling a drawing package is judged on the street elevation first.

No blanket Article 4 over DA17 (Belvedere): Bexley Council has not withdrawn permitted development across DA17 (Belvedere), so a drawing package outside a DA17 (Belvedere) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a DA17 owner wants on file.

Outer south-east London suburban; very permissive planning environment; strong PD uptake for extensions and loft conversions.

What happens if a DA17 property sits on a boundary?

• Greenwich — cross the DA17 (Belvedere) boundary and Greenwich Council takes the drawing package instead, applying 20 conservation areas of its own around SE3. We re-price architectural drawings at the DA17 (Belvedere) edge because Greenwich policy and Bexley policy rarely align on drawing package depth.
• Bromley — the Bromley boundary runs against Bexley, so a drawing package a street from DA17 (Belvedere) is decided by Bromley Council instead. Bromley runs 48 conservation areas across BR1 and its neighbours, which is why architectural drawings priced for DA17 (Belvedere) are re-checked against Bromley policy whenever the DA17 (Belvedere) address sits on that edge.
