Detailed floor-plan drawing for a London property — planning drawings in London
The brief

What the client needed

A family in Barnehurst approached us for planning + building regs full package on a 1930s semi-detached property. Constraints: respecting streetscape rhythm typical of Bexley, maintaining rear garden depth, and meeting Bexley Council's design expectations for the conservation context (16 conservation areas borough-wide).

Design response

How we designed it

Measured survey week 1. Three design iterations balancing internal layout against external massing visible from neighbours. Two scheme massings tested against Bexley Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.

Planning route

Where in Barnehurst does a planning drawings actually get determined?

Every Barnehurst postcode district we draw in, the stock that dominates it and the authority that validates a planning drawings there. Barnehurst fees below are the statutory England rates for 2026, not planning drawings estimates.

How does a planning drawings differ street by street across Barnehurst?

Roof pitch, wall build-up and plot depth change every few Barnehurst streets, and each one changes what a planning drawings can achieve at that address.

Does Barnehurst planning policy restrict a planning drawings?

Barnehurst conservation designations: there are 16 across Bexley Council, Crayford, Welling, Bexley Village among them. Designation costs a Barnehurst owner the permitted-development route: a planning drawings then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Bexley Village is the Barnehurst designation that most often changes a planning drawings design.

No blanket Article 4 over Barnehurst: Bexley Council has not withdrawn permitted development across Barnehurst, so a planning drawings outside a Barnehurst conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a DA7 owner wants on file.

What Barnehurst 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 planning drawings route in Barnehurst more than the postcode does.
