Building in London
The London development market
London projects are dominated by flats: conversions of houses and commercial buildings, infill and backland sites, and mid-rise blocks. Tight sites, party walls, overheating risk and London Plan energy policies all shape what is needed, and boroughs set their own planning conditions, so the paperwork varies from one borough to the next.
Typical London projects we support
- House-to-flat conversions
- Commercial-to-residential conversions above shops
- Backland and infill sites
- Mid-rise apartment blocks and roof extensions
Councils we work across
We handle Air Tightness Testing for sites in the 32 London boroughs, the City of London Corporation and nearby Hertfordshire, Essex, Kent and Surrey councils, and coordinate with whichever planning and Building Control body covers your site.
