Which DA1 postcodes does this drawing package service cover?
Every DA1 postcode district we draw in, the stock that dominates
it and the authority that validates a drawing package there. DA1 fees below are the
statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|
| DA1 | Crayford / Dartford fringe | Victorian terraces, 1930s semi-detached | Which council depends on which side of the boundary the property stands. DA1 straddles it: Dartford Borough Council determines drawing packages for Dartford, Wilmington, Stone and the Kent addresses around them, while the London Borough of Bexley takes the Crayford streets at the western edge. Two local plans, two sets of case officers, one postcode district. The boundary is checked at the address before a package is issued. |

What local planning policy applies to a drawing package in DA1?
DA1 (Crayford / Dartford fringe) conservation designations: there are 16 across Bexley Council, Welling, Bexley Village, Old Bexley among them. Designation costs a DA1 (Crayford / Dartford fringe) 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. Welling is the DA1 (Crayford / Dartford fringe) designation that most often changes a drawing package design.
No blanket Article 4 over DA1 (Crayford / Dartford fringe): Bexley Council has not withdrawn permitted development across DA1 (Crayford / Dartford fringe), so a drawing package outside a DA1 (Crayford / Dartford fringe) conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a DA1 owner wants on file.
DA1 (Crayford / Dartford fringe) housing stock: 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. Read that before choosing a drawing package route in DA1 (Crayford / Dartford fringe) — construction, not postcode, sets what is achievable. Bexley Council charges £548 for a householder application and has 8 weeks to determine it.
What happens if a DA1 property sits on a boundary?
- Greenwich — cross the DA1 (Crayford / Dartford fringe) 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 DA1 (Crayford / Dartford fringe) edge because Greenwich policy and Bexley policy rarely align on drawing package depth.
- Bromley — adjoining DA1 (Crayford / Dartford fringe), with 48 conservation areas centred on BR1. A drawing package on the far side of the DA1 (Crayford / Dartford fringe) line is determined by Bromley Council, so the DA1 (Crayford / Dartford fringe) quote for architectural drawings is checked against Bromley guidance before it is issued.
