Across Haringey the standard breast takes about half a square metre out of every room it stands in, so a house with four of them is giving up two square metres of floor. Removing them is a plain gain. We arrange the structural engineer, the steel and the building control inspections.
Chimney breast removal in Haringey's Victorian homes
Most Haringey terraces still carry their original chimney breasts on the party wall, one serving the front reception, one the rear. Homeowners in Crouch End and Muswell Hill often want the breast gone to reclaim floor space in a first-floor bedroom or a ground-floor reception. Because the breast helps carry the masonry above, every job starts with a structural engineer confirming what the retained stack needs to keep it supported.
On lower floors we support the retained stack with steel gallows brackets bolted firmly into the party wall, or a beam where brackets are unsuitable for the loading. Where the stack runs the full height of one of Haringey's taller terraces, we often remove it entirely and make the roof good instead, which avoids leaving a heavy masonry mass hanging above with nothing beneath it.
Party wall and building control in N22
Haringey's terraces are tightly packed and the chimney stack almost always sits within the party wall shared with next door, so removing a breast or bolting in gallows brackets is notifiable under the Party Wall Act. You serve notice on your neighbour before work starts, keeping the shared wall and the relationship intact.
The structural support is notifiable under building regulations, and Haringey Council's building control signs it off, not the planning department, since this is internal work. We manage everything: the engineer's calculations, safe removal and propping, capping any redundant flue with ventilation to prevent damp, and replastering so there is no sign the breast was ever there.
Chimney stacks inside a converted loft
A great many Haringey terraces have a loft conversion, and the chimney stack usually runs straight through the new room. That changes the job in two ways. The steels carrying the loft floor and the new roof may bear on or close to the stack, so nothing comes out below until the engineer has confirmed what those steels sit on, and the stack itself is often boxed in and plastered so the brickwork cannot be seen.
Where the loft stack is redundant it can often come out as part of the same project, which reclaims usable width in a room short of it and takes weight off the structure below. Where it is retained, it needs supporting properly rather than resting on the loft floor. In N8 and N10 houses where the conversion was done years ago and the paperwork has gone, we open up enough to see how it was built before anything is designed.
- Ventilated caps and airbricks to disused flues
- Making good, plastering and reinstating the wall line
- Party Wall Act notices for stacks in a shared wall
- Flue capping with ventilation to keep the stack dry
- Fireplace opening infill and new plasterboard finish
