Extending a Primrose Hill house at the rear or below ground
An extension joins new work to a building with its own logic. In Primrose Hill, that may mean stock brick rear walls, butterfly parapets, earlier rear additions and a garden bounded by brick walls. Camden’s appraisal also notes mature private trees, though tree cover varies from street to street. Going below ground is not an ordinary room extension, since it brings ground, water and drainage risk. Structural, drainage and waterproofing design are coordinated before any digging.
Planning, building control, party wall duties and tree protection each run on their own track. Check Tree Preservation Order and conservation-area status for the exact address, and allow any statutory notice period before work to trees. Camden’s older area statement resists harmful infill or enlargement of lightwells, though current policy and the actual proposal decide the outcome. For a listed house, listed building consent is a further application. In a flat, extending may need consent under the lease.
Where a Primrose Hill house has no side access, spoil, blocks and steel may pass through the building itself. The route from vehicle to garden is surveyed for door widths, turns and basement steps. Scaffold, storage and mixing areas are placed clear of roots and canopies, with arboricultural advice where trees are close. A skip or hoarding on the road needs a licence from the highway authority for that exact spot. Boundary walls and railings are protected until the last load leaves.
Include the address, tenure, photographs of the rear elevation and garden, and any trees near the proposed footprint. Mention known drains, boundary walls and any neighbouring extensions. Hampstead Renovations then prepares a written scope that keeps planning, building control and party wall steps as separate items in the programme. The build is carried out in-house, and site protection drawings show the walls, railings and trees to be kept.
