Blackheath: Dual Borough Before Any Basement Box

Authority first

Blackheath village and heath-edge houses can sit in Royal Borough of Greenwich or Lewisham. A wrong authority on the location plan invalidates the package before trees or neighbours are assessed. Pure SE10 Greenwich freeholds do not share that dual-borough failure mode.

See Blackheath basements versus Greenwich basements for the different first sheets.

What stops digs after the LPA is fixed

Garden trees, dual flanks and short courts more often stop Blackheath digs than tourist-core access that dominates Greenwich town digs. Lightwells are sized against neighbour windows and heath-edge character before structure freezes. At Hampstead Architecture & Planning, our in-house architectural designers, architects, and structural engineers coordinate the planning drawings, hydrological and structural method statements, and subsequent Building Regulations package alongside our sister companies Hampstead Chartered Surveyors & Building Consultancy and Hampstead Renovations — ensuring Party Wall awards and construction sequencing align with the consented envelope. Before any basement drawing set is uploaded to the Royal Borough of Greenwich or London Borough of Lewisham planning portal, we verify the conservation area boundary, Article 4 coverage, tree preservation orders, and highway spoil-lorry routing so the submission passes validation on first deposit and gives adjoining owners clear technical reassurance.
