GS Renovation removes redundant chimney breasts across Westminster, from the Regency terraces of Pimlico to the mansion blocks near Paddington and Marylebone. Drawing on 30+ years of structural work in SW1, W1, W2 and W9, we free up floor space, support the stack above and leave the room squared off and replastered.
Chimney breast removal in Westminster terraces
Westminster's Georgian and Regency townhouses were built with multiple flues, and many still carry chimney breasts that no longer serve a fire. Because the breast helps support the masonry stack rising through the floors above, we never simply knock it out. A structural engineer assesses exactly what the breast is carrying, and we design a support that holds the retained stack safely once the breast below is gone.
On the lower floors of a Pimlico or Belgravia terrace we support the stack above with steel gallows brackets bolted into the party wall, or a small beam where brackets are unsuitable. In the taller houses of Mayfair and Marylebone, where the stack runs the full height, it is often better to remove the whole stack and make the roof good. We cap any redundant flue and ventilate it to keep damp at bay.
Party wall duties in Westminster W1
In Westminster's tightly packed terraces the chimney stack almost always sits within the shared party wall, so removing the breast, or bolting gallows brackets into that wall, is notifiable under the Party Wall Act. We serve notice on the adjoining owner in SW1 or W1 before work starts and agree the arrangements. Where your flat is leasehold in a period mansion block, we instead obtain the freeholder's licence to alter.
The support work is notifiable under the Building Regulations too, and Westminster City Council's building control signs it off. Planning permission is not involved for this internal work, though if your home is listed, common across Mayfair and Belgravia, altering original chimney features can need listed-building consent, so we check first. We manage the engineer's design, the party wall notices, safe removal and propping, capping and replastering, from start to finish.
