MCIAT chartered. Greenwich planning experienced. 1 postcode covered: SE3.
The borough-level guide to planning drawings in Greenwich sets out how the same work is handled across the rest of the authority.
Blackheath (Greenwich) is Georgian villas around the heath. The dominant stock — georgian villas, victorian terraces — has specific constraints and opportunities for planning permission drawings. Side returns sit better on bay-fronted Victorian terraces than on detached 1930s semis. Mansards work where the existing roofscape supports them. We design to the block, not the brochure.

Blackheath (Greenwich) conservation designations: there are 20 across Greenwich Council, Charlton, Eltham Park, Greenwich Town Centre (World Heritage Site) among them.

Greenwich Town Centre (World Heritage Site) is the Blackheath (Greenwich) designation that most often changes a planning drawing set design.
No blanket Article 4 over Blackheath (Greenwich): Greenwich Council has not withdrawn permitted development across Blackheath (Greenwich), so a planning drawing set outside a Blackheath (Greenwich) conservation area usually keeps it.
