Before a wall comes out, someone has to establish what it is carrying, and the age of the house shapes that answer. The Valuation Office Agency counts 3,250 dwellings in the Old Amersham area, of which 350 were built before 1900. We appoint the structural engineer, build to the calculations, and coordinate the Buckinghamshire Council application and inspections.
Establishing what is carrying load in older Amersham stock
Age is the first clue, and Amersham's is published. The Valuation Office Agency counts 3,250 dwellings in the Old Amersham area, of which 350 were built before 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.
Repeated house designs on the Weller Estate
The Weller Estate was built to a small number of designs. The council's appraisal records that 84 of the 113 houses in the main part of that conservation area are to a single Metropolitan Railway Country Estates design. A further 12 are the slightly smaller chalet bungalow variation of it. Repetition helps an engineer form an expectation, but it does not replace an inspection of your own house.
The building control route for one or two walls
Buckinghamshire Council allows a building notice for work that includes removing one or two internal load-bearing walls. The council states that work can start 48 hours after it has received the application and payment. That is the lighter of the two routes, and we coordinate the application and the inspections either way.
As a guide, indicative London ranges, MyBuilder and Checkatrade, 2026, put a full knock through, including the wall removal, the engineer's fee and making good, at £2,500 to £6,500 and above. Your quotation is free and carries no obligation.

Why Amersham Homeowners Choose GS Renovation
Because the wall is the straightforward part and the consent route is where projects stall. Buckinghamshire Council's building notice route covers removing one or two internal load-bearing walls, and it is the route we use where it fits.
