The question worth asking first is what stays. Taking a breast out on the ground floor alone leaves everything above it needing support; taking the stack right up through the roof avoids that but brings roof work and retiling. We price both for Putney homeowners, with a structural engineer's calculations either way.
Chimney breast removal in Putney terraces
Most Putney terraces still carry their original chimney breasts in the front and middle rooms, and because the houses are joined, the flues and stack usually sit within the party wall shared with next door. The breast helps carry the masonry and stack above it, so every removal starts with a structural engineer assessing exactly what the breast supports before any brickwork is opened up.
On the lower floors we support the retained stack above with steel gallows brackets bolted firmly into the party wall, or a beam where brackets are unsuitable for the loads. Where a breast runs the full height of a taller Putney terrace, we more often remove the whole stack and make good the roof rather than leave masonry perched on brackets. A stack is never left unsupported.
Party wall and building control in SW15
As Putney's terraces are tightly packed, the chimney stack almost always sits within the shared party wall, so removing the breast or fixing gallows brackets into that wall is notifiable under the Party Wall Act. You serve the correct notice on the adjoining owner before work begins and record the condition of both properties, keeping the neighbours informed and the job on the right footing.
The structural support is controlled under the Building Regulations, and Wandsworth Council's building control inspects and signs it off; this is not a planning matter unless external work is involved in a conservation area. We manage the lot: the engineer's assessment, safe removal and propping, capping any redundant flue with proper ventilation to prevent damp, and replastering so the room finishes clean and square.
The fireplace question in a Putney house
Once the breast is gone the fireplace goes with it, and that is a decision worth taking deliberately rather than by default. An open fire or a stove is a genuine asset in an SW15 terrace, and reinstating one later is a far bigger job than simply keeping it. If you want that option, the flue has to remain lined and serviceable, which changes what can be removed and where the support goes.
The hearth is the second part of it. It is a concrete slab set below floor level, and once it comes up the joists have to be trimmed and the floor let in. Original boards can be matched where the room deserves it, or the whole floor relaid. And if the chimneypiece is period and you want it kept, it needs taking off carefully and storing before demolition, not rescuing from the rubble afterwards. Both points need settling before the engineer is briefed, since a retained flue changes what the support has to do.
Buying a house where one already went
A fair share of the calls we take in SW15 are about somebody else's work. A house near Putney Heath comes with a nice flat wall in the back bedroom, no paperwork at all, and nobody in the chain who can say who did it or when. It is worth understanding what that means before you commit, because masonry left hanging above is a genuine problem and a properly supported one is no problem whatever.
There are things you can look at yourself. See whether the breast is still there in the room above, look for a stack on the roof, and check the ceiling below for cracking along the line of the old brickwork. Past that it takes opening up. We are glad to walk round a house you are buying and tell you what is likely to be there, so the remedial work can go into your offer rather than surprise you later.
