Much of Greenwich sits in a conservation area and a good deal of it is listed, so consents come first and demolition second. Approval under the building regulations is required regardless. We coordinate the structural engineer's design for the beam, the applications and the inspections, then carry out the work and make good.
Removing a chimney breast in Greenwich
Most of Greenwich's period homes still carry their original chimney breasts, and in the borough's tightly built terraces the flues are often shared through the party wall with the house next door. Because the breast helps carry the masonry and stack above it, we never simply cut one out; we begin with a structural engineer establishing precisely what that breast is holding up before any demolition.
On the lower floors we support the retained stack above with steel gallows brackets bolted firmly into the party wall, or a small beam where brackets are unsuitable for the masonry. In the taller Georgian townhouses of SE10 and around Blackheath, where the stack runs the full height, we more often remove the whole stack and make good the roof so nothing is ever left unsupported.
Party wall and building control in Greenwich
As Greenwich's Victorian and Georgian terraces sit shoulder to shoulder, the chimney stack almost always lies within the shared party wall, so removing the breast or fixing gallows brackets is notifiable under the Party Wall Act. You serve notice on the neighbour before work starts and keep the process straightforward for both households.
The structural support is controlled under the Building Regulations, and the Royal Borough of Greenwich's building control inspects and signs it off; this is not a planning matter unless you are altering the exterior of a listed building or working in a conservation area. We manage all of it: the engineer's design, safe propped removal, capping any redundant flue with ventilation against damp, and replastering so no trace of the breast remains.
From first visit to final certificate
The build itself is the short part. A Greenwich chimney breast removal usually runs to six or seven weeks end to end, and most of that happens before anyone lifts a tool. The first week is the survey and the engineer's visit. The second produces the design and the building regulations application. Where the house is listed or the flue is shared, consent and the party wall notice period run alongside, and neither of those can be hurried along.
Steel is then fabricated to the engineer's schedule once the design is settled, which takes several days more. Only after that does site work begin, and the removal, support and making good typically occupy a week to ten days in a house near Greenwich Park. The certificate follows the final inspection. We set the whole programme out at quotation stage so you can plan around it rather than discover it as you go.
Reclaiming bricks, grates and surrounds
A Greenwich chimney breast is built from material worth keeping. The bricks are usually London stocks laid in lime mortar, which means they clean up and can be used again, and in a conservation area that counts for something if you have garden walls or a rear elevation that will need matching repairs later. We set sound stocks aside on request rather than sending the lot to the transfer station.
The fireplace itself is often the better find. Cast iron register grates, slate and marble surrounds and original tiled slips all survive behind later boarding, and in a listed Greenwich house the consents may say something about what can come out at all. We open up carefully and tell you what is there before anything gets broken. Owners tend to reuse a piece elsewhere in the house, sell it through one of the salvage yards, or ask us to arrange collection.
