Building in Hampstead

What working in Hampstead actually involves

Hampstead is where our London work concentrates. Space is won downwards and upwards: basement excavation, mansard roofs, full width rear extensions and complete internal reconfiguration of period houses.

Logistics matter as much as construction. Narrow streets, controlled parking, neighbouring party walls and active local amenity societies all shape how a project is planned and sequenced.

Planning policy in Hampstead

The constraints we test before design begins, not after a refusal.

  • The London Borough of Camden determines applications, and Camden applies specific basement policy controlling depth, footprint and impact on structure and groundwater.
  • Hampstead has extensive conservation area coverage and a very high concentration of listed buildings.
  • A basement impact assessment covering groundwater, structural stability and drainage is normally required.
  • Party Wall awards, schedules of condition and movement monitoring are standard on excavation work here.
  • Article 4 directions restrict permitted development, so rights should never be assumed.
