Buildings around Borough High Street sit tightly packed, and the chimney is almost always in the shared wall, so the Party Wall Act applies and notice must be served. We prepare the notices, agree access, and programme the work to suit the neighbours. Then the engineer's steel goes in and the room is put back together.
Removing a chimney breast in Borough
Many Borough homes still carry their original chimney breasts in the front and middle rooms, long after the open fires stopped being used. Because the breast helps carry the masonry and stack above it, we never treat removal as a simple knock-out. Every job starts with a structural engineer confirming what sits overhead and how the retained brickwork will be held once the breast at that level is gone.
Where we remove a breast on a lower floor but the stack continues up through the house, we support the retained masonry on steel gallows brackets bolted into the party wall, or on a small beam where brackets are unsuitable. In taller SE1 terraces where the stack is fully redundant, we often take the whole stack down and make the roof good, so nothing is ever left hanging unsupported.
Party wall and building control in SE1
In Borough's tightly packed Victorian and Edwardian terraces, the chimney stack almost always sits within the party wall shared with the house next door. That makes removing the breast, and bolting gallows brackets into the shared masonry, notifiable under the Party Wall Act. You serve the correct notice on your neighbour before work starts, so the shared wall is protected and everyone knows what is happening.
The structural support we install is notifiable under the Building Regulations, so Southwark Council's building control inspects and signs it off. We handle the engineer's calculations, the propping and safe removal, cap any redundant flue with ventilation to stop damp forming, and replaster so there is no trace the breast was ever there. You get a tidy chimney alcove and a certified result.
Working in a tight SE1 street
Chimney removal produces a surprising volume of brick, mortar and soot, and around Borough High Street there is rarely a front garden to stand it in. We plan the waste route out of the building before anything comes down, protect the stairs and hallway, and arrange either a permitted skip or a grab collection, since a skip standing on the public highway needs a licence from Southwark Council and often a parking suspension. Soot is dusty and it stains, so the flue is swept and bagged before any breaking out begins.
Noise is the other consideration in closely built SE1 property. Breaking out brickwork is loud and it travels through party structures, so we agree hours in advance and give neighbours warning. In a leasehold flat the building's own rules on working hours and lift use apply on top of everything else, and where the property is listed or in a conservation area, altering the visible stack needs consent first.
Doing this before the rewire and replaster
The order you do things in decides how much you pay for twice. Removing a chimney breast opens a wall, disturbs the floor at the hearth and leaves a fresh patch of plaster behind, so it belongs near the start of a programme of works rather than at the end of one. We are regularly called to SE1 flats where the ground floor was replastered and an engineered oak floor laid last year, and the breast is now coming out through both of them.
If a rewire is coming, do the removal first. The electrician then chases and drops cables into a wall that is already in its final position instead of working around brickwork about to disappear. The same applies to flooring, which should go down after the hearth void is filled and levelled, and to any fitted joinery. Around Borough Market many flats sit above shops and restaurants, where access to the space below is negotiated once rather than repeatedly.
