An Edwardian bay-fronted house off Green Lanes gives up around 0.5 square metres to the breast in the front room and the same again upstairs. Owners here usually do both floors at once and save on the propping and the plastering. Support is a beam to the engineer's specification, approved under the building regulations.
Chimney breasts in Palmers Green terraces
Most terraces and semis around Palmers Green still carry their original chimney breasts, and in these tightly built N13 streets the flues are shared through the party wall with the house next door. Because the breast also helps carry the masonry and stack above, we never simply cut it out. A structural engineer first assesses what the breast is holding so the correct support can be designed.
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 brackets are not suitable for the loading. Where the stack runs the full height of the house and is no longer wanted, we more often remove it entirely and make the roof good, rather than leave masonry propped high above the room.
Party wall and building control in N13
Because Palmers Green's terraces share a party wall with the neighbouring house, the chimney stack almost always sits within that shared wall. Removing the breast or fixing gallows brackets affects the party wall, so the work is notifiable under the Party Wall Act and you serve notice on the neighbour before starting. This keeps everyone informed and the job properly documented.
The structural support is notifiable under the Building Regulations, so Enfield Council's building control inspects and signs it off. We manage the whole process: the engineer's assessment, safe removal and support of the stack, capping any redundant flue with ventilation to prevent damp, and replastering so there is no trace the breast was ever there.
Salts, staining and the right plaster
Old flues are full of soot and tar, and those deposits carry salts that travel into the surrounding brickwork. Plaster straight over contaminated masonry and within a few months you get brown or yellow staining pushing through the paint, particularly in an Edwardian house off Green Lanes where the flue burned solid fuel for decades. It is not damp coming in from outside. It is what the chimney left behind.
The answer is in the preparation. We hack off back to bare brick where the breast stood, brush the face down, and where staining is likely use a salt retardant backing or a renovating plaster rather than ordinary bonding. A capped flue is vented so it stays dry. The wall is then allowed to dry properly before decoration, because painting too early traps moisture and the stain returns through the new emulsion. That is why a plastered wall still looks clean two winters on.
The room loses its focal point
A fireplace gave the room a centre. Furniture faced it, the bay was balanced against it and everything else in an Edwardian front room off Green Lanes was arranged around that one point on the wall. Remove the breast and the room becomes a plain rectangle with nothing to look at, which is a gain in floor area and a loss in character. Owners who have not thought about it usually end up pushing the sofa against the longest wall and living with a room that feels a little aimless.
It is worth deciding in advance what takes over. Often that is the television, which then wants power, aerial and data run to a considered position rather than trailed across the skirting. Sometimes it is a piece of joinery, a large picture with a light over it, or the bay itself, brought forward with a window seat so the room looks outward instead. In a symmetrical Palmers Green terrace the answer usually respects the original symmetry, because a room built to balance rarely reads well left lopsided.
