Interwar houses near Danson Park have shallower breasts than Victorian ones, projecting around 300mm, but they sit in party walls that are thin in places. That affects how the beam can bear. Our structural engineer works to the wall you actually have rather than a typical detail, and we build to what they draw.
Chimney breast removal in Bexleyheath semis
Many 1930s semis in Bexleyheath still carry their original chimney breasts, projecting into the reception rooms and the bedrooms above and stealing usable floor space. With open fires long redundant, homeowners in DA6 often want them gone. Because the breast helps carry the masonry and the stack above it, we begin every removal with a structural engineer confirming exactly what is being supported before anything is cut away.
Where we remove a breast on the lower floors but keep the stack higher up, the retained masonry must be supported by steel gallows brackets bolted into the party wall, or by a beam where brackets are unsuitable. In many Bexleyheath houses the whole stack is now redundant, so removing it in full and making the roof good is the tidier answer. We never leave a stack unsupported.
Party wall and building control in DA6
Bexleyheath's semis share a party wall with the attached house, and the chimney stack very often sits within that shared wall. Removing the breast or bolting gallows brackets into it affects the party wall, so the work is notifiable under the Party Wall Act and you serve notice on your neighbour before starting. We prepare those notices as part of the job so nothing is overlooked.
The structural support for the retained stack is notifiable under the Building Regulations, and Bexley Council's building control signs it off, no planning permission is involved for internal work. We handle the lot: the engineer's design, safe staged removal and propping, capping any redundant flue with ventilation to prevent damp, and replastering so there is no trace the breast was ever there.
Making the room good afterwards
Once a Bexleyheath breast is out, what is left is a scar across three surfaces. The floor comes first. An interwar house has a constructional hearth of solid concrete under the fireplace, sitting below the level of the surrounding boards, so we break it out and either splice in new joists and boarding or fill and level it, depending on how the rest of the floor is built. Getting that flat matters if the room is being carpeted.
The wall behind is usually bare brick, sometimes with a soot-stained render that will bleed through paint if it is simply skimmed over. We hack it back, apply a salt-resistant coat and plaster to a flat line with the adjoining wall. Skirting is then run through in a matching profile and the picture rail, where the bedroom has one, is made continuous. Done properly, the only clue is that the room measures wider than before.
