House extensions in West Hampstead: fabric, consent and access

An extension in West Hampstead joins new work to old fabric. A red-brick terrace may have a narrow rear route, a party wall on each side and a garden reached only through the house. An individual house may have more room at the side, but its boundaries still need checking. Where a house has been converted into flats, the garden and rear wall may belong to the freeholder. Brick colour, bond and mortar profile guide how new work meets the original.

Extensions engage the widest set of controls. Planning permission or permitted development depends on the exact address, including whether West End Green Conservation Area, a listing or an Article 4 direction applies. Building Regulations deal with structure, drainage and energy performance. Foundations close to a neighbour’s building or on the boundary can fall under the Party Wall etc. Act. For flats, lease and freeholder consent sit alongside all three. We check Camden’s planning history before design begins.

Excavation spoil, concrete and steel all need a route out and in. For a West Hampstead terrace, that route may run through the hall, so protection and sequencing matter as much as the build itself. A skip or scaffold on the highway needs a licence from the right authority. On densely parked side streets, smaller timed deliveries are more dependable than stockpiles. Shared rear boundaries mean neighbours hear what to expect before any digging starts.

An extension brief works best with the full address, tenure and any planning references you hold. Send photographs of the rear elevation, the garden and any neighbouring extensions. Add known drainage runs, trees near the boundary and the rooms you want to gain. Hampstead Renovations then agrees a written scope, separating surveys, approvals, groundworks, structure and finishes. Our own team builds the extension and records drainage and structural connections before they are covered.
