House extensions on Dartmouth Park’s sloping, retained plots
Camden publishes a topography map for the Dartmouth Park conservation area, and levels decide what an extension can do. Gardens step between retaining walls, and a ground floor can sit below the street at one side. Water already moves downhill through the plots. We read floor and garden levels, existing walls and drainage for the exact address before a footprint is drawn. Cracks and sticking doors on the uphill side are noted, because they may point to movement that a new load would meet.
Conservation-area status, Article 4 coverage and the Dartmouth Park Neighbourhood Plan, adopted in March 2020 after a referendum, are confirmed for the exact address. The Plan is weighed alongside the Local Plan but cannot approve an extension on its own. Camden added energy-efficiency guidance for the conservation area in August 2012. Building Regulations approval and Party Wall etc. Act notices remain separate. A basement or lightwell would change the consent route again.
On a sloping Dartmouth Park street, scaffold and mixing areas stand on sole boards levelled to the fall of the ground. Where they occupy a road Camden controls, the building licence comes first. Spoil from a rear dig may come up steps rather than through a level door. The footing is inspected after heavy rain, since water runs downhill across the base. Neighbouring retaining walls are protected and photographed before excavation.
Mention whether a basement, lightwell or garden excavation is proposed on the Dartmouth Park plot. Add photographs of the rear garden, its walls and the current ground floor, plus any planning history you hold. Hampstead Renovations agrees a written scope covering levels, drainage, approvals and build. The extension is constructed in-house, with hold points before foundations are poured.
