House extensions in South Hampstead, shaped by gardens and trees

An extension changes the garden as much as the house. Camden’s appraisal gives unusual weight to South Hampstead’s private rear gardens and communal green spaces, for amenity, wildlife, drainage and calm. A rear addition, excavation or new paving can affect all of these together. Early feasibility maps trees, levels, drainage, neighbouring structures and the original garden extent. The junction with late-Victorian brickwork also matters, because new work should not trap moisture in the old wall.

Extensions draw on several approvals that run separately. Whether planning permission is needed at a South Hampstead house turns on Camden’s conservation map, the Article 4 schedule and planning history for the exact address. Building Regulations approval is a distinct process. Work on a boundary or excavation near a neighbour’s foundations can bring in the Party Wall etc. Act. Trees bring their own procedure: formal notice for works in a conservation area unless an exception applies, and separate protection under any Tree Preservation Order.

Rear work at a South Hampstead house can mean spoil, blocks and steel travel through the house. Where there is no side access, floors, doors and original tiles along the route are protected first. Camden’s standard noisy-work hours end at 1pm on Saturdays, and unauthorised noisy work is not allowed on Sundays or bank holidays. Skips on the highway go through Camden’s licence process, and a parking suspension is needed where one occupies a space. Neighbours hear about deliveries and noisy phases in advance.

Describe how the extended space should work, from a kitchen opening onto the garden to a quieter family room. Include any measured survey, drawings, planning history and tree information you hold. Photograph the rear elevation, the garden and the boundaries with each neighbour. Give the exact address and tenure, and for a ground-floor flat, share the lease. Hampstead Renovations then prepares a written scope that sequences approvals, structure, drainage and finishes. Our in-house team builds the extension and photographs concealed work before it is covered.
