House extensions on streets facing Hampstead Heath

Rear walls on streets around South End Green, Parliament Hill and East Heath Road can be seen from open land as well as from neighbouring gardens. An extension facing Hampstead Heath therefore joins the house to a view the public already uses. We record stock brick or stucco, existing additions, garden levels and how water leaves the plot. High brick garden walls on East Heath Road can also limit where a vehicle unloads, which is noted at survey.

Several Camden conservation areas cover streets near Hampstead Heath, some with Article 4 directions and some without. Camden’s Article 4 page lists a 1989 direction for specified even-numbered houses on South Hill Park, plus a schedule for the Hampstead Conservation Area. Further directions adopted in June 2026 are re-read for the exact address. The Heath itself is managed by the City of London Corporation, which is a different body from the planning authority. Building Regulations and party wall notices remain separate.

East Heath Road winds uphill from South End Road towards Whitestone Pond. A stopping point for steel, blocks and spoil is agreed before ordering, because walls and trees can block a lorry. Scaffold near the Heath edge may meet trees on or close to the boundary, so pruning waits for Camden’s tree answer. A building licence is obtained where the scaffold base falls on the highway. Neighbours on the downhill side hear about excavation before it starts.

Share the conservation-area and Article 4 results if you have them, photographs of the rear and the Heath-facing slope, and any basement idea, because that would need a Basement Impact Assessment. Hampstead Renovations then agrees a written scope covering design, structure, drainage and consents. The extension is built in-house, with each approval filed beside the finished drawings.

Could house extension in Hampstead Heath involve the Party Wall Act?
