GS Renovation removes chimney breasts throughout Dulwich, from the period villas near Dulwich Park to the Victorian and Edwardian terraces across SE21. With over 30 years of structural work in Southwark, we take out redundant breasts to reclaim space, properly support the stack above and leave the room squared off and replastered.
Removing a chimney breast in Dulwich terraces
Most Dulwich homes still carry their original chimney breasts, and in these bay-fronted terraces the flues run through the party wall shared with the house next door. Because the breast helps carry the brickwork of the stack above, taking it out on a lower floor leaves that masonry needing support, so we begin every job with a structural engineer's assessment of exactly what sits overhead.
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 unsuitable for the geometry. In the taller SE21 houses where the stack runs the full height, we more often remove the whole stack and make good the roof. We never leave a stack hanging unsupported, whatever the layout.
Party wall and building control in SE21
Because Dulwich terraces are built tight against one another, 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 neighbour before work starts and manage the correspondence, which keeps things civil on a close-knit SE21 street and protects you if questions arise later.
The structural support you install is notifiable under the Building Regulations, and Southwark Council's building control signs it off. We manage the whole sequence: the engineer's calculations, the party wall notices, safe removal with propping, capping any redundant flue with ventilation to stop damp forming, and replastering the wall so there is no trace the breast was ever there. You are left with a certificate and a clean room.
