- Rated 4.9 from 31 reviews on MyBuilder
- Guide from £2,500 (London-derived)
- Free site survey, itemised quote
Before a wall comes out, someone has to establish what it is carrying, and the age of the house shapes that answer. Old Amersham has 3,250 dwellings on Valuation Office Agency figures, 350 of them built before 1900. We bring in the structural engineer, work to their calculations and manage the Buckinghamshire Council application and inspections.
For Amersham, on London-derived ranges 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; Buckinghamshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Amersham.

How the job runs
- Free site survey at your Amersham address and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with Buckinghamshire Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- The floor above is propped, the wall comes out and the beam is set on padstones.
- Building control inspects the steel before it is covered. We make good, and the completion certificate follows.
Establishing what is carrying load in older Amersham stock
Age is the first clue, and Amersham's is published. In the Old Amersham area the Valuation Office Agency counts 3,250 dwellings, and 350 of those predate 1900. In fabric of that age the load path has to be established by opening up and inspecting, not assumed from the floor plan.
Elm Close, in Amersham-on-the-Hill, is a documented case. The council records 30 houses there, built by the Amersham Public Utility Society Ltd to designs by Mr J H and Mr L Kennard between late 1920 and early 1922. A recorded design gives the engineer a starting point. The inspection still governs.
Housing in Amersham
By the valuation list's count, Amersham holds about 7,670 homes, 78% houses and 22% flats; by age, 11% were built before 1919, 21% between the wars and 68% since 1945. Every wall in a detached house in Amersham is the owner's, so no party wall notice arises, and 31% of homes here are detached.
Repeated house designs on the Weller Estate
The Weller Estate was built to a small number of designs. Of the 113 houses in the main part of that conservation area, the council's appraisal puts 84 on one Metropolitan Railway Country Estates design. Its slightly smaller chalet bungalow version accounts for another 12. A shared design tells an engineer what to expect; only an inspection of your house confirms it.
The building control route for one or two walls
Taking out one or two internal load-bearing walls can go to Buckinghamshire Council on a building notice. Once it has the application and payment, the council says, work can begin after 48 hours. That is the lighter of the two routes, and we coordinate the application and the inspections either way.
Indicative London ranges (MyBuilder and Checkatrade, 2026) suggest £2,500 to £6,500 and above for a full knock through, with wall removal, engineer's fee and making good included, as a guide only. Quoting for your wall costs you nothing.

FAQ
Frequently Asked Questions about Load-Bearing Wall Removal Amersham
Is a cheap load-bearing wall removal quote in Amersham worth taking?
Be careful with a cheap load-bearing wall removal quote in Amersham, particularly if nobody has visited. Pricing a post-war suburban home unseen is how a low figure becomes a high one halfway through, because whether the wall carries the floor above decides if a beam is needed. GS Renovation surveys, itemises within £2,500 to £6,500 or more per opening (London-derived) and holds the total. A second opinion on the HP6 quotation costs nothing.
We want three internal walls out, not two. Does that change the building control route?
It can. Buckinghamshire Council's wording puts removing one or two internal load-bearing walls under a building notice, while extensive internal structural alterations to any building need a full plans application. Three walls sits outside that first wording, so ask the council to confirm the route before the programme is set. Full plans needs drawings and calculations submitted when you apply, which the engineer we appoint prepares.
The wall we want out has a chimney breast sitting on it. Does that change the job?
Yes, because the breast above becomes part of what the new beam carries, along with the floor and anything else the wall was supporting. The engineer inspects at every floor the stack passes through before sizing anything. In Old Amersham the stack may continue above the roof, where the council's appraisal treats chimney stacks as part of the street scene. The calculations then go to building control with the application.
Our house is in the Elm Close conservation area. Does that stop us taking an internal wall out?
No. The designation is about the character of the estate as it is seen, and the council's leaflet shows no listed buildings in either Elm Close or the Weller Estate. The aim of both designations was to preserve good examples of the period's estate house building. Internal structural work goes to Buckinghamshire Council as a building control matter. Ask the council to confirm your address is not separately listed before you settle the design.
Can we leave a pier at one end instead of taking the whole wall out?
Yes, and a retained pier changes the steel rather than removing the need for it. A nib left at one end gives the engineer a bearing point, which can shorten the span and reduce the depth of the beam. It is still an alteration to the structure, so Buckinghamshire Council sees the same drawings and calculations and inspects the same work. The engineer decides where a pier helps and where it does not.
