Building work in Harlesden: area guide

This is our area guide to building work in Harlesden (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 Harlesden.

Most Harlesden homes are flats, on VOA figures, and the terraces around Harlesden High Street and the Jubilee Clock were built quickly and cheaply for railway workers. It shows: two rooms deep, a cramped rear addition, solid brickwork, a small yard and no real rear access. In a flat, freeholder consent and the shared soil stack come first. Where a terrace is still a house the brief is space: a usable kitchen and dining area, a third bedroom, a ground floor that is not a corridor with rooms attached. The building is rarely complicated. Doing it with no barrow route round the back is the skill.

Take the 6,350 or so homes the valuation list gives Harlesden: 83% flats, 17% houses, 78% from before 1919, 4% interwar and 18% post-war. VOA Council Tax stock of properties, March 2025, for Harlesden. Counts rounded by the VOA.

Winning space in a small terrace: chimney, opening or infill

Three moves do most of the work in the houses, each a job of its own. Chimney breast removal recovers width in the bedrooms and front reception, because a breast and its hearth take a genuine bite out of a small floor plan. Opening between front and rear rooms is load-bearing wall removal, and it turns two dark spaces into one that works. Filling in beside the rear addition, house extensions where the plot allows, gives a kitchen the width it never had. Each puts load from masonry onto a beam designed by the engineer we appoint.

Chimney removal is the item people underestimate. Taking a breast out at ground floor leaves everything above it, sometimes two more storeys of brickwork and a stack above the roofline, needing support, and gallows brackets are not accepted for anything substantial. The answer is a designed steel picking the stack up and carrying it to sound bearings. It is notifiable, building control inspects it, and where a stack is shared with next door it is also notifiable under the Party Wall etc. Act. In a converted flat the freeholder's licence comes first. Planned from the start, none of that adds much to a programme.

Everything goes through the front door, steel included

There is no side gate on most of these houses, so spoil, timber, plasterboard, steel and waste all travel through the hallway, and in a flat through a communal one as well. We protect floors and the staircase before anything arrives, run a covered route to the working area, and keep a barrow route that does not wreck the finishes we are trying to keep. Excavated material from foundations comes out the same way, straight into a skip or bags. It is slower than a job with rear access and entirely predictable once it is priced and programmed properly.

Kerb space is the other scarce resource. Parking on the streets off the High Street is controlled, so we apply for the skip permit and any bay suspension from Brent Council before work is booked, and deliveries are timed rather than left open. Scaffold to the rear of a terrace usually has to be carried through the house or across a neighbour's ground, which needs their agreement in advance. We speak to neighbours early, keep the frontage swept, and pull materials in as needed instead of stacking a week of them on the pavement.
