Chimney Breast Removal Forest Gate

Growing families around Woodgrange Road tend to reach the same conclusion: the chimney breast has to go before another wardrobe will fit. Taking it out on both floors gives back close to a square metre. We appoint the structural engineer, install the beam that carries what stays above, and cap and ventilate the disused flue.

In Forest Gate, 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 Forest Gate.

How the job runs

1. Free site survey at your Forest Gate 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 Newham 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 Forest Gate

Most Forest Gate terraces still carry their original chimney breasts in the reception rooms and bedrooms, projecting into rooms that families would rather use fully. These breasts were built to serve open fires that are long redundant, but the masonry above still needs carrying once the breast below is taken away. That is why we never treat removal as a simple knock-out job in these E7 homes.

A structural engineer first assesses what the breast is supporting. On the lower floors we support the retained stack on a steel beam bearing into the party wall, or on gallows brackets bolted into it where the engineer and building control accept them. Where the stack runs the full height of the terrace and is no longer of use, we more often remove it entirely and make good the roof, so nothing is ever left standing unsupported.

Housing in Forest Gate

For Forest Gate the Council Tax list gives about 11,180 homes; by type 51% flats and 49% houses, by age 31% post-war, 1% interwar and 67% older than 1919. Where most homes are flats, a chimney breast in a flat in Forest Gate often supports the breasts in the flats above, so removal needs the freeholder's licence and designed support.

Forest Gate chimney breasts taken out by earlier owners, and the 1985 line

A Forest Gate house built before the First World War can reach you with a breast already missing, taken out by an owner decades ago. Whether that removal can be put on record turns on when it happened. Newham Building Control can regularise building work done after 11 November 1985 by checking it is of a good standard. For a breast removed since then, the route is to expose the support, whether a steel, brackets or nothing at all, and have the structural engineer we appoint confirm or redesign it before Newham inspects. For older removals there is no regularisation route, so the engineer's written assessment becomes the record.

When a removal is planned now, Newham lists removing a chimney breast among the minor works suited to a building notice. In Forest Gate, where 67% of homes date from before 1919, the notice is a short step inside a longer sequence. The engineer's design comes first, then your party wall notice as building owner where the breast is built on the party wall, and a check on the flue next door. If the house is in the Romford Road or Woodgrange Estate conservation areas, both under comprehensive Article 4 directions, ask Newham whether taking a stack down above the roof falls within them before a roofer is booked.

Party wall and building control in E7

Forest Gate terraces sit wall to wall, and the chimney stack almost always sits within the party wall shared with the house next door. Because removing the breast, and bearing a beam or fixing brackets into that wall, affects shared structure, the work is notifiable under the Party Wall Act, so you serve notice on your neighbour as building owner before starting. Handling this properly avoids disputes and keeps the neighbour on side.

The structural support is notifiable under the Building Regulations, and Newham Council's building control inspects and signs it off. No planning permission is needed for internal chimney breast removal in E7, but a listed building needs listed building consent, and taking the external stack down in a conservation area is worth checking with Newham first. We manage the whole job: calculations from the engineer we appoint, safe propped removal, capping any redundant flue with ventilation against damp, and replastering.

How the build era shapes the method

Forest Gate's terraces went up between the 1880s and the First World War, which dates the construction closely enough to predict what sits behind the plaster. Flues are lined with parging rather than clay liners, so they crumble as soon as they are disturbed. Breasts are solid brick in lime mortar. And the party wall is often a single brick thick with the neighbour's flue running alongside yours inside the same structure.

That last point drives the method more than anything else. Cutting into a shared stack risks breaking through into the flue next door, so we work back gradually and check as we go rather than swinging a breaker at it. It is also why bracket details need care in these houses, since the wall may not be substantial enough to take them, which is one reason a beam has become the more usual answer. Roof coverings of this era are usually slate on softwood battens, so any stack taken down to roof level needs the covering carefully cut back and reinstated.
