Chimney Breast Removal Richmond

Richmond has more listed buildings than most London boroughs, and listed building consent is a separate matter from building regulations approval. Both may apply. We tell you which at the survey, coordinate the structural engineer's design for supporting the stack, and carry out the work with the making good matched to the house.

In Richmond upon Thames, 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 Richmond upon Thames.

How the job runs

1. Free site survey at your Richmond upon Thames 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 Richmond 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 Richmond homes

Most of Richmond's period houses still carry their original chimney breasts, and in the borough's terraces the flues are usually shared with the neighbour through the party wall. Because the breast helps carry the masonry above it, we never take one out on assumption. A structural engineer first assesses exactly what the retained stack weighs and how it must be held once the breast below has gone.

On the lower floors we support the 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 taller Georgian townhouses around TW10 where the stack runs full height, it is often better to remove the whole stack and make the roof good. Either way, no stack is ever left standing unsupported.

Housing in Richmond upon Thames

Count the homes in Richmond upon Thames and you get about 85,810: 37% built since 1945, 24% between the wars and 38% before 1919, with flats at 42% and houses at 58%. 29% of homes here are terraced; the breasts of a terrace in Richmond upon Thames usually sit on the party wall back to back with next door's, so removing one needs a party wall notice.

Chimneys on Richmond upon Thames streets with an Article 4 Direction

Richmond's list of changes that can need planning permission where a home is subject to an Article 4 Direction includes extensions and additions, new doors and windows, and removing chimneys. The borough lists directions in conservation area CA22 covering Clarence Road, Teddington, and CA47 covering Queen's Road, Twickenham, among others, and each direction sets out the works it covers. Where yours includes chimneys, a chimney stops being only a building control and party wall question. Taking a stack down above the roof, which some owners want once the breasts below have gone, then becomes a planning application in its own right, with the time and uncertainty that brings.

The practical answer on a direction street is usually to keep the stack and take out only what is inside. The breast comes out, the structural engineer we appoint designs steel to carry the retained stack, and the roofline the direction protects stays as it is. 29% of homes in Richmond upon Thames are terraced houses, and in a terrace the stack normally stands on the party wall with the neighbour's flues in it. As building owner you serve party wall notice before the breast is cut, and the support is designed for the whole stack rather than your half.

Party wall and sign-off in TW postcodes

Because Richmond's terraces sit tightly together, the chimney stack almost always falls within the shared party wall, so removing the breast or bearing a beam into that wall is notifiable under the Party Wall Act. You serve the notices on the neighbour as building owner before any work starts, keeping things clear and neighbourly on both sides of the wall.

The structural support is notifiable under the Building Regulations, and Richmond Council's building control inspects and certifies it. We manage the lot: the engineer's design, safe removal and propping, capping any redundant flue with ventilation to keep damp out, and replastering so there is no sign the breast was ever there. If your home is listed, listed building consent is needed before the breast comes out.

Listed building consent in practice

Richmond has more listed buildings than most London boroughs, and inside a listed building the rules are different. Listing covers the interior as well as the elevations, so a chimney breast, its opening and any surviving fireplace form part of the listed fabric. Removing one needs listed building consent from Richmond Council, and that is a separate application from anything to do with the Building Regulations.

In practice the conservation officer will want to know what is being lost, whether the breast is original, and what is being retained elsewhere in the house. Consent is often given where the breast is a later addition or the room has already been altered, and refused where it is the last untouched feature in a principal room. It takes time, so we establish the listing position at the first visit rather than after a design has been paid for. Carrying out the work without consent is an offence, not a paperwork problem.

The first year after the work

A large area of new plaster moves slightly as it dries and as the house goes through its first heating season, so a hairline crack appearing where new work meets old is normal rather than a fault. We would sooner tell you that at the outset than have you worrying about it in November. It happens in any Richmond house and it happens rather more in the older ones, where lime plaster and modern gypsum meet along the same wall.

So we leave you with a tube of decorator's caulk and the advice to fill and touch in after a winter rather than straight away. Anything structural is a different matter entirely. If a door begins to bind, or a crack widens instead of settling, we want to hear about it and we come back to look. Most of what owners ring about in the first year is decoration, and most of it takes five minutes to put right.
