Planning Permission in Blackheath | Fixed-Fee Plans

No Article 4 Direction covers Lewisham, which keeps the Blackheath permitted-development route open on unlisted houses. The prevailing character of Blackheath — Georgian and Victorian villas around the heath — sets what Lewisham Council will accept near All Saints Church and what it will resist. Inside the Hither Green boundary — one of 30 such designations in Lewisham — a Blackheath scheme normally goes straight to a full Lewisham Council application rather than relying on permitted development. We establish it for the SE3 address before any drawing begins.

Article 4 coverage across SE3 is confirmed before we quote, not after. The georgian villas in Blackheath decides the depth before policy does. The borough policy layer over every SE3 address is set out on Lewisham planning. The Blackheath survey then carries into building regulations drawings in Blackheath if the project runs on to construction.

Validation alone costs London Borough of Lewisham one to two weeks even when the Blackheath pack is complete, and that queue — not the determination — is where most SE3 delay starts. The first visit to Blackheath is a measured survey — every room, every opening, every level change recorded on site.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

An officer report on the SE3 case is written after the consultation closes. A Blackheath pack that misses a scale bar is a pack London Borough of Lewisham will reject — ours do not.

Most Blackheath refusals trace back to overlooking, not to size. Drainage runs and manhole positions on the SE3 plot are picked up on the day.

Serve SE3 party wall notices before work starts, not after. Once consent is granted, loft conversion drawings follows for the SE3 property.

Blackheath is characterised by georgian villas, victorian terraces, concentrated across SE3 in the Blackheath / Kidbrooke area. On Blackheath plots, structure follows the georgian villas that is already there. On SE3 plots specifically, applications on Georgian stock here almost always need a heritage statement alongside the drawings. For a Blackheath owner it decides the structural spec. Massing on a Blackheath scheme is argued against the All Saints Church street rhythm.

A SE3 dig turns on engineering more than on policy. A Blackheath survey done once feeds house extension drawings for SE3 properties and architectural drawings later.

We are architectural technologists, MCIAT chartered, and every Blackheath set carries that accountability. On a marginal Blackheath plot we would rather spend on Lewisham Council pre-application advice than lose 8 weeks to a refusal on a SE3 address.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.
