House extensions in Hampstead Garden Suburb under three maps

Hampstead Garden Suburb houses were designed as part of a planted composition of closes, greens and hedges, not as isolated objects. An extension therefore meets original brick, tile, joinery and garden setting together. We record rear walls, existing additions, trees and hard standing before a footprint is drawn. New work is matched to surviving fabric rather than to a catalogue period style.

Three consent maps overlap, and they do not match exactly. Barnet’s conservation area, designated in 1968, runs from the Heath Extension north to East End Road. Two Article 4 directions remove permitted development rights within it. The Hampstead Garden Suburb Trust operates a separate Scheme of Management over an area that is not entirely the same. Planning, Trust consent and Building Regulations approval are sequenced as distinct steps for the exact address. Party wall notices can still apply.

Access on the Suburb’s closes and greens is tight, and parking is part of the design rather than an afterthought. Scaffold, skips and stored materials stay off hedges and root zones. Tree and hedge work can need its own consent under the Scheme of Management as well as Barnet’s tree rules. Deliveries are sized for the actual close, and neighbours are told the working pattern before excavation.

Plot the house on each of the three maps if you can, and send photographs of the rear, garden, hedges and any earlier additions. Include Trust correspondence you already hold. Hampstead Renovations agrees a written scope covering planning, Trust, building control and construction. The extension is built in-house once each decision is in hand.
