Building work in Willesden: area guide

This is our area guide to building work in Willesden (NW10, Brent): the housing, the council rules that apply (Brent Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Willesden.

The Victorian terraces here have been divided and subdivided for generations, and a large share of the work we take on in NW10 involves flats that were once rooms in a family house. Those conversions were often carried out quickly, with stud partitions run across old joists, services chased in wherever there was room, and very little thought given to the sound and fire separation between one home and the next. Putting such a flat right, or returning a divided house to single occupation, is as much about correcting that history as about better kitchens and more daylight.

The Council Tax list puts Willesden at about 9,160 homes, 77% flats against 23% houses; 64% went up before 1919, 8% between the wars and 28% after 1945. VOA Council Tax stock of properties, March 2025, for Willesden Green and Church End. Counts rounded by the VOA.

Flats carved out of Victorian houses: licence and structure first

The typical NW10 conversion flat shows its origins as soon as work starts. Floors bounce because joists were notched for pipe runs, sound passes between homes because the separating floor is the original boards, ceiling and nothing else, and fire doors on the common stair are either missing or painted shut. A separating floor can be upgraded with a resilient build-up, an independent ceiling and proper flanking detail, and the escape route made compliant, all designed around the head height actually available.

Structure has to be checked before anything else is planned. Walls that look like conversion era studwork sometimes turn out to be original masonry carrying joists, which makes taking one out load-bearing wall removal, and openings formed during the conversion were not always designed at all. We bring in a structural engineer to survey what is there, build to the design that comes back, and notify building control. Because work to a flat touches fabric other people rely on, the freeholder's licence to alter, or the agreement of the other owners where the freehold is shared, comes before the programme rather than during it.

Bringing a house back together needs planning first

Reversing a conversion is a satisfying project and a bureaucratic one. Turning two or three flats back into a single dwelling can count as a material change of use, so planning permission is often needed, and the leases have to be dealt with legally before building work starts. On site it is a full strip out: separate kitchens and bathrooms removed, meters and services rationalised, the staircase reopened, floor levels reconciled where a conversion raised them, and the ground floor opened up so the house reads as one home again. That is the home renovation route, with an open-plan conversion element.

Living arrangements shape the sequence in either case. Where neighbours remain in the building throughout, the shared stair has to stay usable and safe as an escape route every working day. We agree working hours before starting, give notice of noisy stages, sheet the common parts, and keep the frontage on the residential streets off the High Road clear. Parking is controlled around Willesden Green station, so a skip permit and any bay suspension are arranged well before the start and deliveries are timed rather than left to chance.
