Clerkenwell's converted workshops throw up stacks in odd places, some serving old industrial flues rather than fireplaces. Before we quote, we open up and check what the breast is actually carrying. If it comes out, the load above goes onto a beam designed by the structural engineer we appoint, with building control involved from the start.
Removing a chimney breast in Clerkenwell
Not every Clerkenwell flat has a chimney breast; the newer riverside-style apartments never did. But the converted Victorian workshops and warehouse buildings often retain original breasts and flues from their industrial days. Because the breast helps carry the brickwork above it, we begin every removal with a structural engineer confirming exactly what load the masonry is supporting before anything is taken down.
On lower floors we support the retained stack above with steel gallows brackets bolted into solid masonry, or a small beam where brackets are unsuitable. Where a stack runs the full height of the building, it is often cleaner to remove the whole thing and make the roof good. A retained stack is never left hanging unsupported, whatever the floor level.
Freeholder consent and party walls in EC1
In a leasehold Clerkenwell flat, removing a chimney breast needs the freeholder's licence to alter and the managing agent's sign-off, since it touches structure the building owner is responsible for. We prepare the engineer's support drawing for that consent and work to any building-management conditions, including protecting common parts and meeting sound-insulation standards between flats.
Where the stack sits within a wall shared with the adjoining flat or building, removal is notifiable under the Party Wall Act and you serve notice on that neighbour first. The structural support is controlled under the Building Regulations, so Islington Council's building control signs it off. We also cap any redundant flue with ventilation to prevent damp, then replaster so the room is left clean.
Working inside a managed EC1 block
In a managed building the constraints are as much administrative as structural. Most blocks around Exmouth Market and Clerkenwell Green set working hours, want notice to the managing agent before a contractor starts, and ask for proof of public liability insurance and a method statement. Some restrict use of the lift for materials or require it to be protected, which changes how a tonne of brick rubble leaves the building.
We plan that route before the first day. Rubble goes out in bags carried down rather than dropped through a stairwell, communal carpet and lift interiors are protected, and the common parts are cleaned at the end of each day rather than the end of the job. Neighbours in a block live close to the work, so we tell them what is happening and which days are the noisy ones. Getting this right is usually what makes a freeholder comfortable.
