Chimney breast removal with gallows bracket or beam support in Soho. Trusted, professional, 30+ years' hands-on experience.
Upper-floor flats above the shops on Dean Street and Berwick Street are awkward jobs: no parking, narrow stairs and a business trading underneath. We bag the masonry and carry it out by hand, work to the engineer's beam design so the stack above stays properly supported, and book building control in for inspection at the right stages.

Most of Soho's Victorian and Edwardian terraces still carry their original chimney breasts, and homeowners reclaim the floor space by removing the ones no longer used for a fire. Because the breast forms part of the masonry and helps carry the brickwork above it, this is a structural job, never a simple demolition. We start with a structural engineer's assessment of exactly what the stack and breast are supporting on each floor.
Where a breast is removed on a lower floor but the stack above is kept, we support that retained masonry on steel gallows brackets bolted firmly into the party wall, or on a beam where brackets are unsuitable for the geometry. In many W1 terraces the flue runs full height, and there it is often cleaner to remove the whole stack and make the roof good. We never leave a stack unsupported.
Soho's terraces sit wall to wall, so the chimney stack almost always lies within the party wall you share with the building next door. Removing the breast, fixing gallows brackets into that wall or taking the stack down are all works to the shared structure, which makes them notifiable under the Party Wall Act. You serve notice on the adjoining owner before work begins, so nothing is done to the shared wall without the proper agreement in place.
The structural support for the retained stack is notifiable under the Building Regulations, and Westminster City Council's building control inspects and signs it off. We manage the lot: the engineer's calculations, safe removal and propping, capping any redundant flue with ventilation to guard against damp, then replastering so there is no sign the breast was ever there. The room is left squared off, clean and ready to decorate.
Any Soho flat altered between the 1950s and the late 1990s may contain asbestos, and a chimney breast is a place it turns up. Textured coatings on the ceiling, insulating board used to block a fireplace opening, old flue packing and the backing to a night storage heater are all candidates. Breaking any of them out without knowing releases fibres through a small flat in minutes.
So where the age and construction suggest it, a refurbishment and demolition survey is carried out before we start, and the results decide the method. Non-licensed materials can be removed with controlled methods and correct disposal; licensed materials go to a licensed contractor with the appropriate notification. Nothing is drilled, sanded or broken until that is settled. It adds a few days at the front of the job and it is not a step we skip, whatever the programme pressure from the business trading below.
A good number of Soho flats are let rather than owner occupied, and that changes the job before it changes the method. A landlord ordering the work needs the tenant on side, because somebody has to give access each morning and somebody has to live with a room out of use. Agreeing dates through the managing agent well in advance avoids the far more expensive problem of a crew standing outside a locked door on Dean Street.
Where a flat is between tenancies the answer is simple, and that is when we would suggest doing it. Where it is not, we work one room at a time and hand back a clean, usable space each evening rather than leaving tools and sheeting spread through the flat. Around Berwick Street Market the loading restrictions mean deliveries and collections are timed to the hour, so a confirmed access slot matters more here than almost anywhere else.

FAQ
Scope, programme and price, on one document. For a Soho property the chimney breast removal quotation sets out what is being done, in what order, and what each element costs, including the Westminster City Council building control fee. Exclusions are stated plainly rather than left to be discovered at W1. Homeowners across Westminster get the same format from GS Renovation. Ring 07472 424 226 or email info@gsrenovationltd.co.uk and we will arrange a free survey at the W1 property. As a rough guide, chimney breast removal in London costs roughly £1,500 to £2,500 for a single floor where gallows brackets are accepted, or £2,200 to £3,250 where a steel beam is needed, which is the more common route now that LABC has withdrawn its standard gallows detail; two floors run £3,000 to £5,000 (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Allow for the structural stage, the following trades and the making good as three separate blocks. On a chimney breast removal project at a W1 address the first is usually shorter than Soho homeowners expect and the last longer, particularly in bay-fronted Victorian terraced housing. GS Renovation gives you the week by week programme with the quotation. The Westminster City Council inspections are marked on it in advance. Email info@gsrenovationltd.co.uk and we will send a sample Westminster programme before the W1 survey.
One accountable team, full insurance, and no surprises on the invoice. GS Renovation carries out chimney breast removal at your W1 address with its own people, agrees any variation in writing first, and hands over the Westminster City Council completion certificate at the end. That document matters when a Soho property is sold. Free quotes and no obligation apply across Westminster. Email info@gsrenovationltd.co.uk and we will arrange a visit. The Westminster certificate is yours at completion.
On a steel beam, or on gallows brackets bolted to the party wall where the building inspector accepts them. LABC withdrew its standard gallows detail in 2024, so most inspectors now prefer a beam. The engineer specifies which suits your W1 property and Westminster City Council inspects it.
Yes, mainly in the preparation and the making good rather than the structural work itself. Chimney breast removal at a W1 property of that age means confirming the load path before design, then reinstating plaster, floors and joinery to match. GS Renovation programmes both into the Soho job. The structural stage is broadly comparable to a modern Westminster house. Ask on 07472 424 226 what chimney breast removal means in practice at a W1 address of that age.
Building Regulations approval as a minimum, and usually more. In W1 that means Westminster City Council's completion certificate, the structural engineer's design behind it, and evidence of party wall notice on a building this tightly packed. Listed building consent applies where the property is designated, and leasehold consent where the flat sits above commercial premises. We collate the set at handover so it exists when you come to sell.
Both, and the borough is not the limit. GS Renovation carries out chimney breast removal throughout Soho and the W1 area and across neighbouring areas, which is why the team is rarely far from a W1 property. Free survey, written quotation, no obligation. Email info@gsrenovationltd.co.uk with the address for a visit. We will say plainly if a Central London property is too far out. Aftercare and snagging afterwards are handled from the same W1 team as the build.
