House extensions in St John’s Wood gardens and settings

Extending a St John’s Wood house often means building into a garden that helps define the neighbourhood. Westminster’s audit describes a low-density suburb of villas, generous gardens and wide, tree-lined streets. On Hamilton Terrace, it records plots up to 60 metres deep. An extension here has to respect trees, drainage and the relationship between house and garden. Our feasibility survey records levels, root zones, existing drains and the original fabric of the rear elevation.

Planning permission, Building Regulations approval and any listed building consent are separate decisions. The exact address shows whether Westminster or Camden decides, and which conservation map applies. Trees in a conservation area need written notice to the council before pruning or felling. Foundations dug close to a neighbour can engage the Party Wall etc. Act. If the scheme adds a basement at a Westminster address, the council’s city-wide Article 4 direction means a planning application is needed.

Access to a rear garden decides much of an extension programme in St John’s Wood. Detached villas may have side access. Terraced houses often do not, so materials and spoil pass through the house under protection. Excavated soil fills a skip quickly, and a skip in a Westminster street needs a council licence. Westminster normally allows building work from 8am to 6pm on weekdays and 8am to 1pm on Saturdays. Camden addresses follow Camden’s own rules.

An extension brief works best when it starts with how the household wants to live, then turns to size. Share photographs of the rear elevation and garden, any tree reports, existing drawings and past planning decisions. Mention neighbours’ extensions and any concerns you already know about. Hampstead Renovations coordinates measured survey, design, structural and drainage input into a written scope. Our in-house team then builds it, keeping the site tidy and the named neighbour contact informed.
