How do conservation areas and Article 4 affect a drawing package in DA14?

Conservation areas covering DA14 (Sidcup): Bexley Council runs 16, and Crayford, Welling, Bexley Village are the ones DA14 (Sidcup) owners meet most. A drawing package inside a DA14 (Sidcup) conservation area loses permitted development, so the DA14 (Sidcup) 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.

DA14 (Sidcup) permitted development status: there is no borough-wide direction from Bexley Council, so a drawing package at a DA14 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a DA14 (Sidcup) sale to argue it later.

What DA14 (Sidcup) is built from: 1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and Erith. Outer south-east London suburban; very permissive planning environment; strong PD uptake for extensions and loft conversions. That mix decides the drawing package route in DA14 (Sidcup) more than the postcode does, and it is what a Bexley Council case officer reads first. A householder application costs £548 paid to Bexley Council direct, with 8 weeks to a decision once validated.

What happens if a DA14 property sits on a boundary?

• Greenwich — cross the DA14 (Sidcup) 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 DA14 (Sidcup) edge because Greenwich policy and Bexley policy rarely align on drawing package depth.
• Bromley — adjoining DA14 (Sidcup), with 48 conservation areas centred on BR1. A drawing package on the far side of the DA14 (Sidcup) line is determined by Bromley Council, so the DA14 (Sidcup) quote for architectural drawings is checked against Bromley guidance before it is issued.
