Approval under the building regulations is required for this work whether the house is a Georgian townhouse near Borough Market or a Victorian terrace out towards Peckham Rye. We make the application, book the inspections and hold the certificate at the end. The steel supporting the retained stack is specified by a structural engineer.
Removing a chimney breast in Southwark
Most of Southwark's period homes still carry their original chimney breasts, and in the borough's tightly packed Victorian and Georgian terraces the flues are shared with the neighbouring house through the party wall. Because the breast helps carry the masonry stack above, we begin every removal with a structural engineer assessing exactly what sits on top of it before anything is taken down.
On the lower floors we support the retained stack with steel gallows brackets bolted firmly into the party wall, or a small beam where the brickwork or bracket geometry does not suit brackets. In the taller SE21 and SE22 townhouses, where a stack runs the full height of the house, we more often remove the whole stack and make the roof good rather than leave weight hanging on brackets.
Party wall and building control in Southwark
Because Southwark's terraces share a party wall, the chimney stack almost always sits within it, so removing the breast or fixing gallows brackets is notifiable under the Party Wall Act. You serve notice on the adjoining owner before work starts and agree the condition of the shared wall. In Bermondsey's converted warehouses the flues may sit differently, and any structural change there needs the freeholder's licence to alter.
The structural support is a Building Regulations matter, so Southwark Council's building control signs off the gallows brackets or beam, not the planning department. We manage the lot: the engineer's assessment, safe removal and propping, capping and ventilating any redundant flue to prevent damp, and replastering so the room is left clean and level.
What we salvage and what gets recycled
A Victorian breast in a Peckham or Camberwell house is built from London stock bricks that are worth keeping. They clean up and are far better matched to the house than anything you can buy new, so we set aside the sound ones for reuse in the parting face, a garden wall or a future repair, and only the frogged rubbish goes for crushing. Cast iron fireplace inserts and stone surrounds are lifted out whole wherever the fixings allow.
The rest is segregated rather than mixed. Brick and mortar rubble, timber, metals and plasterboard all go to different streams, and plasterboard in particular cannot go to landfill mixed with general waste. We use licensed carriers and keep the transfer notes, which is the part of the duty of care most homeowners never see but which sits with you as well as with us. It costs nothing extra to do it properly on a job this size.
Measure the gain before you commit
A chimney breast in a Southwark terrace projects a few hundred millimetres into the room and takes a metre or so of wall width away with it. Written down like that it sounds small. The honest test is to mark the outline on the floor in masking tape, then put the wardrobe, the sofa or the bed roughly where you imagine it going and live with the tape for a week before deciding anything at all.
Owners are regularly surprised in both directions. In a narrow Peckham or Camberwell bedroom the gain is the difference between a double bed against the right wall and one jammed under the window, and it is obviously worth doing. In a large through reception near Dulwich Park it sometimes turns out the alcoves were more useful than the extra floor, and the money would be better spent on joinery instead. We would far rather you worked that out with a roll of tape than after the brickwork has gone.
