Building work in Brentford: area guide

This is our area guide to building work in Brentford (TW8, Hounslow): the housing, the council rules that apply (Hounslow Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Brentford.

Brentford has changed shape faster than most of west London. Along the Grand Union Canal and the river towards Kew Bridge, apartment blocks framed in concrete and steel now sit alongside the older terraces behind the High Street, and the two route to different jobs. In a framed flat the structure is fixed and the rules come from the lease and the management company. In a period house the rules come from the fabric and the council. GS Renovation works across TW8 on both, coordinating engineers and Hounslow Council building control as required.

About 13,230 homes are listed for Brentford, and the mix is 35% houses to 65% flats, with 61% built after 1945, 24% in 1919 to 1939 and 15% earlier. VOA Council Tax stock of properties, March 2025, for Brentford Central, Brentford West & Osterley Park and Brentford East. Counts rounded by the VOA.

Brentford framed flats: the stack and the slab decide the room

In a concrete or steel framed building the internal partitions typically carry nothing, so an open-plan conversion job has real freedom, while the columns, cores and slabs are untouchable without a designed solution. Drainage is the other fixed element: every waste run needs a continuous gradient back to the stack the building already has, and the slab cannot be cut to help it. That is why a kitchen renovation or bathroom renovation here is planned around where the pipework can actually go, sometimes on a raised plinth or with a pumped system. Everything else follows from those two fixed points.

Ventilation and heating are frequently communal too. Mechanical ventilation units, heat interface units and riser cupboards belong to the building rather than the flat, so a new extract or a moved radiator has to work with the system already there. We establish all of this at survey, before a layout is drawn, which avoids a design that turns out to be undeliverable once the risers are opened. Where a riser has to be opened, the management company is involved from the outset.

Managing agents set the terms in TW8 blocks, the street elsewhere

Estate and block management sets the practical terms of work in a TW8 flat. Working hours, lift bookings, protection of communal floors, parking for a van and how waste leaves the site are all determined by the managing agent, and skips are rarely permitted on private estates. Your lease will also require a licence to alter for anything structural or for moved services, and the freeholder's appointed surveyor will expect a drawing pack, a written method statement and proof of insurance before granting it. We supply that documentation routinely.

The Victorian and Edwardian terraces behind the High Street and towards Brentford station operate under the ordinary rules. Solid walls, suspended timber floors, load bearing spine walls and shallow foundations: taking out a spine wall is a load-bearing wall removal job, designed by an engineer and inspected by Hounslow Council building control. Here the constraints are on the street rather than in a lease: narrow frontages, permit parking and a skip that needs a highway licence before delivery. We apply for that licence, and time deliveries around the school and commuter peaks on the surrounding streets.
