House extensions in Hendon on hilltop plots and later streets

An extension in Hendon has to meet the slope as well as the house. Greyhound Hill falls toward Watford Way, so surface water, drain gradients and any retaining wall belong in the first survey. Church End is a linear development linking Church Road with Watford Way, with St Mary’s at its heart. Later houses after 1927 are not guessed from the road name. We record the rear wall, levels and existing drains before a footprint is drawn.

Inside Church End or The Burroughs, rights to extend are narrower, so more work needs a planning application. The council weighs the setting of listed buildings such as Church Farm House and the parish church, and a large rear addition seen from the hillside can raise that question. Outside both areas a lawful development certificate can confirm permitted development. Building Regulations approval and party wall notices run as their own lines. We confirm the map for the exact address.

Excavation on a slope needs a route for spoil that does not send water onto a neighbour. Before digging, long-term flood risk is checked on GOV. UK and existing drains are traced with a camera. Deeper work close to a neighbour’s foundations can require notice under the Party Wall etc. Act. A skip or scaffold on the highway is licensed by Barnet or TfL, confirmed for the frontage. Root zones of conservation-area trees are marked on the site plan.

Bring photographs of the rear slope, the roof and any retaining wall, plus planning history if you hold it. Say whether you believe the Hendon house sits in Church End or The Burroughs. Hampstead Renovations then agrees a written scope covering investigation, consents, structure and making good. Our own teams build the extension, and drains and steel are photographed before they are covered.
