House extensions in Childs Hill, scoped under the right council
Childs Hill sits where Barnet’s ward map meets streets that residents still associate with Hampstead, and the houses themselves are mixed: family homes, converted flats and later infill. An extension has to start from the rear wall, garden levels and drainage of that property. We record chimney breasts, party lines and existing additions before a footprint is drawn. New work is detailed so it does not trap moisture in the original masonry.
A postcode or a place name does not settle which council handles a Childs Hill street. Planning, trees and highway licences are answered only after the exact address is fixed to one authority. For a Barnet address, the council’s interactive tool shows whether permission is needed and explains prior approval for larger single-storey rear extensions. A Camden address follows Camden’s guidance. Building Regulations approval and Party Wall etc. Act notices remain separate in either case.
Kitchen units and excavated soil all need space at the kerb. Barnet issues skip licences to hire firms rather than householders, and inside a controlled parking zone the bay suspension is approved first. On a Camden street, Camden’s own skip and scaffold licences apply instead. If the skip can stand on private land, the boundary is confirmed and the footway kept clear. Spoil from a rear dig often travels through the house, so halls are protected.
Include the full Childs Hill address, tenure, photographs of the rear and garden, and any neighbouring extensions. Say whether a chimney breast or garden opening is part of the idea. Hampstead Renovations prepares a written scope in which structure, drainage and consents are priced as separate lines. Our own teams then build the extension through to handover.
