Planning and building regulation drawings in Dulwich (SE21)

Because so much of the district grew up as one planned villa landscape, the drawings that work here tend to respect the original grain: a rear extension that steps down from the main roofline rather than competing with it, a loft conversion that keeps dormer windows modest against a steep Victorian pitch, roof materials that match rather than contrast. Newer 20th-century infill sits alongside the Victorian stock too, and those properties usually have more room to move design-wise, though many are still on Estate leases. The common thread across almost every project in SE21 is that two separate approvals can be in play at once, planning permission from the council and a second sign-off tied to the property's Estate history, and getting the sequencing right saves weeks.

Planning in Dulwich: what to know before you apply

Southwark decides householder applications with an eye on preserving the character that makes streets like Dulwich Village, College Road and Calton Avenue distinctive: frontage proportions, roofline pitch and traditional materials all get scrutiny once a property sits inside the Dulwich Village conservation area. Mature garden and street trees along these routes often carry preservation orders, which affects how close a dig-out basement or single-storey rear addition can sit to a root protection zone, so we check tree constraints before finalising a layout. Southwark also runs Article 4 control over the district's railway arches, a narrower and more specific restriction than the roofline and elevation rules that come from the conservation area designation. Where a property falls under the Dulwich Estate's own scheme, that consent process runs in parallel with planning, not instead of it, and we build both into the drawing timeline from the outset rather than treating the Estate stage as an afterthought.

Applications are decided by London Borough of Southwark — its planning pages.
