The third bedroom in an Edwardian Catford house is often a box room made smaller still by the chimney. Removing the breast frees the one wall long enough to take a bed or a desk. We prop, cut back, install the engineer's beam over the opening, cap the flue and leave the room replastered and square.
Chimney breasts in Catford's period homes
Most Catford terraces still carry their original chimney breasts, and because the houses are built in tight rows the stacks sit within the party wall shared with next door. The breast helps carry the brickwork and stack above it, so we begin with a structural engineer's assessment of exactly what is being supported before anything is removed.
Where you keep the stack higher up but remove the breast on a lower floor, we support the retained masonry on steel gallows brackets bolted into the party wall, or a beam where brackets are not suitable. In many SE6 houses the sensible option is to take the whole stack out down to roof level and make the roof good.
Party wall and building control in SE6
Because the stack usually sits in the shared party wall, removing the breast or bolting gallows brackets into that wall is notifiable under the Party Wall Act, so you serve notice on your neighbour before work begins. Leaving a stack unsupported is never an option, so the support design is settled and agreed on paper first.
The structural support is notifiable under the Building Regulations, and Lewisham Council's building control inspects and signs it off. We manage the whole sequence: engineer's calculations, safe staged demolition with propping, capping any redundant flue with a vent to stop damp, and replastering so the room looks like the breast was never there.
Earlier removals we uncover in SE6
A fair number of Catford terraces have already had a breast taken out at some point, and not always properly. The tell-tale signs are a hairline crack running diagonally from the corner of the old opening, a bedroom floor that dips towards the party wall, and brackets that were bolted through soft Edwardian brick with no spreader plate. Sometimes there is nothing holding the stack at all beyond the plaster around it, which only became apparent when someone opened the ceiling.
If we find that on your survey, we tell you and the engineer designs a proper remedy, usually a beam bearing onto new padstones each side. It is worth putting right rather than living with, because a solicitor acting for a buyer will ask for a completion certificate that does not exist. Regularisation through Lewisham building control is possible after the event, and we prepare the drawings and open up the work so an inspector can see what is there.
Doing this before the rewire, not after
Order matters more than most people expect. If a rewire, a full replaster or new flooring is anywhere in your plans for the room, the breast wants taking out first. We have walked into Catford houses where an electrician chased new circuits into a wall that was about to be demolished, and into others where an oak floor laid in the spring had to be lifted again in the autumn to trim joists and level the ground where the old hearth had been sitting.
So we ask at survey what else is coming, not just what you have called us about. If the room is being replastered anyway, the making good disappears into that trade and one plasterer visits once. If the house is being rewired, the sparks can set the new socket and radiator positions on a wall that is already flat. Flooring goes last, every time. On an SE6 terrace where several rooms are being done in turn, that sequencing usually saves more than it costs to plan.
