Chimney Breast Removal Peckham

The front room of a Bellenden Road terrace changes character entirely once the breast has gone: one flat wall in place of a chimney and two shallow alcoves. We prop it, take it out, land the masonry above on engineered steel, cap and vent the flue, and plaster the full wall so it reads as original.

In Peckham, removing a breast on one floor typically costs £2,200 to £3,250 on a steel beam, and £3,000 to £5,000 across two floors (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Peckham.

How the job runs

1. Free site survey at your Peckham address: which floors the breast runs through, a shared stack, any live flue.
2. The engineer we appoint designs the support, and the work is registered with Southwark Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. The floor above is propped and the breast comes down in courses from the top; what remains sits on the support the engineer specified.
4. Building control inspects the support before it is covered. We make good, and the completion certificate follows.

Removing a chimney breast in Peckham

Most Victorian and Edwardian houses in SE15 still carry their original chimney breasts in the reception rooms and bedrooms, even where the fires were blocked up years ago. Because the breast helps support the masonry stack rising above it, we never simply knock it out. A structural engineer first works out exactly what weight sits overhead before we decide how to hold it.

On the lower floors, where you want to reclaim the space, we support the retained stack above on a steel beam bearing into the party wall, or on gallows brackets bolted into it only where the engineer and building control accept them. In many Peckham terraces the stack runs the full height of the house, and there we more often remove it entirely and make good the roof, which is cleaner than leaving masonry hanging on brackets alone.

Housing in Peckham

Peckham has about 26,680 homes on the Council Tax list: 36% pre-1919, 2% interwar and 56% post-war, with flats making up 74% and houses 26%. Where most homes are flats, post-war blocks in Peckham rarely have breasts, so one in a flat is checked by the engineer first.

Chimney stacks above Peckham roofs in the conservation areas

Taking out a breast indoors is one decision, and what happens to the stack above the roof is another. In parts of Peckham the second one needs more care. Southwark Council designated the Peckham Hill Street Conservation Area, north of the commercial core of Peckham, on 18 October 2011. Its appraisal says mansard roof extensions would not be considered appropriate given the cohesive roofscape, and taking a stack down changes a roofscape the appraisal describes as cohesive. If the plan includes taking the stack down below the roof line, raise it with Southwark planning before the scaffold goes up, not after the bricks are in the skip.

Southwark's Rye Lane Peckham Conservation Area is principally centred on Rye Lane, Peckham Hill Street and Peckham High Street. Its appraisal says roof extensions should not involve the loss of an historic roof structure, and removing a stack is a change to those same roofs, so treat it with the same care. Keeping the stack and carrying it on steel inside the house leaves the roof untouched and the street view unchanged. Where the stack does come down, agree the engineer's design and the roofing detail together, so the roof is made good in matching materials and the neighbour's half of a shared stack is left sound and weathered.

Party wall and building control in SE15

In Peckham's tightly built terraces near Peckham Rye the chimney stack almost always sits within the party wall shared with the house next door. Removing the breast, or bearing a beam or brackets into that wall, is notifiable under the Party Wall Act, so you serve notice on the neighbour as building owner before any work starts. We give you the drawings the notice needs, which keeps the process straightforward.

The structural support is notifiable under the Building Regulations, and Southwark Council's building control inspects and signs it off; this is not a planning matter for internal work. We manage the lot: the engineer's assessment, safe removal and propping, capping any redundant flue with ventilation to prevent damp, and replastering so there is no trace the breast was ever there.

A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Southwark Council, and doing it without consent is a criminal offence.

Working down the stack floor by floor

Where more than one floor of breast is coming out of an SE15 terrace, the order runs downwards rather than upwards. The topmost section goes first, so nothing is ever left hanging above an opening, and the props on each floor stay in place until the level above is complete and stable. The house is worked through from the loft down to the front room rather than room by room in whatever order happens to suit.

Between each level we stop and check. Masonry left standing is inspected before the next section is touched, and the engineer's drawing sets out where the support lands on each floor. Rubble is cleared as we go rather than allowed to accumulate, because a floor loaded with a tonne of brick is carrying weight it was never designed for. Only when the whole run is down and supported do the making good trades start at the top and work back down.

What makes one job bigger than another

Two Peckham houses on the same street can need quite different jobs, and the reasons are worth understanding before you compare one quote with another. How many floors the breast comes out of is the obvious factor. Less obvious are whether the stack above the roof is going or staying, how much scaffolding the roof work needs, and how the material gets out of a house with no rear access. A property split into flats adds coordination that a single family house simply does not have.

Then there is the making good, which is where estimates differ most. A room with plain plaster and modern skirting is quick. An SE15 house that still has its cornice, picture rail and original boards needs matching work by hand, and that takes time whoever does it. Salvaging a surround, an unexpected back boiler, or damp staining that needs specialist plaster all move the figure as well. We set out what is included and what is provisional, so nothing lands on you halfway through.

• Flue capping with ventilation to keep the stack dry
• Rubble bagged and carried out rather than dropped inside
• Steel beam support on padstones for a retained stack above
