Load-Bearing Wall Removal Kennington

GS Renovation removes load-bearing walls across Kennington, working in the Georgian and Regency townhouses around Cleaver Square and Kennington Road and in the post-war flats that make up most of SE11's homes. We open up these tall, narrow period homes without compromising the masonry above, delivering a properly engineered result rather than a risky shortcut.

In Kennington, a complete single opening typically costs £2,500 to £6,500 or more, including the engineer's calculations, the steel beam, propping and making good (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Kennington.

How the job runs

1. Free site survey at your Kennington address and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Lambeth 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, the wall comes out and the beam is set on padstones.
4. Building control inspects the steel before it is covered. We make good, and the completion certificate follows.

Reading load paths in Kennington townhouses

Kennington's Georgian and Regency houses were built with solid brick spine walls that carry floor joists and, in many cases, the weight of three or four storeys above. In SE11 you rarely find a purely decorative internal wall on the ground floor, so we never assume a wall can simply come down. Every job starts with a structural engineer inspecting the wall, tracing the load path and calculating the steel needed to replace it.

Once the beam is specified, we install padstones to spread the load into the remaining brickwork, prop the structure temporarily and take the wall out in careful staged sections. The RSJ is lifted into place, bolted and packed tight, then the propping comes away only when the beam is fully bearing. In tall Kennington townhouses this staged discipline matters, because there is a great deal of masonry sitting above each opening.

Housing in Kennington

About 8,500 homes are listed for Kennington, and the mix is 18% houses to 82% flats, with 60% built after 1945, 12% in 1919 to 1939 and 28% earlier. Where most homes are flats, a wall in a flat in Kennington may carry the floors above, so the freeholder agrees first.

Removing a wall in a Kennington estate flat means two separate consents

82% of Kennington's homes are flats, and the area's housing is described on the site as post-war council estates around Georgian and Victorian squares. On an estate block the consent you need under the lease comes from whoever holds the freehold, and that is a separate decision from building control even where the landlord is a public body. Expect two separate conversations: one with the landlord about whether a load-bearing wall in a Kennington flat may be touched at all, and one with Lambeth building control about how the replacement steel is approved. Neither approval stands in for the other, and a building control approval does not grant permission under the lease.

Lambeth's building work guidance says Party Wall Act requirements are a civil legal matter between you and your neighbour, and that Lambeth has no role in administering the Act. In an estate block, the neighbour could be the flat below, the flat above or the one beside you, and each may need notice from you as building owner if the work touches structure you share. List every adjoining owner at the start, so notices go out together and no neighbour first hears about the work from the sound of a breaker.

Party wall and building control in SE11

Because Kennington's terraces sit shoulder to shoulder, the flank walls of your house are usually shared party walls with the neighbour. Where a new beam bears into that shared wall, the work becomes notifiable under the Party Wall Act, and you, as building owner, serve notice on the neighbour before we start. We give you the drawings the notice needs, so relations with your neighbour stay straightforward and the job is not held up by a dispute later on.

Removing a load-bearing wall is a Building Regulations matter, not a planning one, so Lambeth Council's building control inspects and signs off the steelwork against the engineer's calculations. Planning permission is not needed for the internal work, but some SE11 houses are listed, and listed building consent covers internal structural work too; doing it without consent is a criminal offence. We hand you the completion paperwork you will need when you come to sell.
