Structural alterations, new openings and steel support in Amersham. Trusted, professional, 30+ years' hands-on experience.
Structural alterations in Amersham are judged against a local plan adopted in 1997 and a core strategy adopted in 2011, both now administered by Buckinghamshire Council. The town also has four conservation areas of its own. We appoint the structural engineer, build to the calculations, and coordinate building control from application to sign off.

Buckinghamshire Council is the local planning authority, and the adopted plan covering Amersham is still the Chiltern District Local Plan, adopted on 1 September 1997. It carries alterations adopted on 29 May 2001 and was consolidated in September 2007 and November 2011.
The Core Strategy for Chiltern District, which sits alongside that local plan, was adopted by the council on 15 November 2011. The two documents have to be read together, so confirm the current position with the council before you commit to a design.
No Article 4 direction on Buckinghamshire Council's register removes householder permitted development rights inside Amersham's built-up area. The directions that touch the town cover poultry production, agricultural buildings and means of enclosure. The direction that once covered development near Amersham train station is recorded as rescinded by Chiltern District Council on 27 March 1991.
The Chilterns National Landscape boundary also excludes both Old Amersham and Amersham-on-the-Hill, including the High Street, the station and Sycamore Road. It does take in land on the south western edge, including the Shardeloes estate and the ground around Amersham Hospital. A 1975 Article 4 direction covers land near Shardeloes House, roughly 1.7 kilometres west of the Old Town and outside the built-up area.
Amersham has four conservation areas of its own: Amersham Old Town, Shardeloes Parkland, Elm Close and the Weller Estate, the last three all designated in 1992.
Two of them contain no listed buildings at all. The council's leaflet shows a dash against Elm Close and the Weller Estate in its listed building count, and says the twentieth century areas were designated mostly to preserve good examples of estate house building of the period. Listed building consent is not the question there. The character of the estate is.
Buckinghamshire Council requires a full plans building control application for extensive internal structural alterations to any building, and for loft conversions. Across the two areas covering Amersham the Valuation Office Agency counts 7,670 dwellings, 2,430 of them built before 1945.
We appoint the structural engineer, submit the application, and build to the approved drawings. Inspections are booked and attended as the work reaches each stage. You get one point of contact for the engineer, the council and the site.
Because this is a contractor's job, not a designer's. We do not produce structural calculations and we are not surveyors or architects. We appoint a structural engineer to produce the calculations, build precisely to what is specified, and coordinate the Buckinghamshire Council building control application and inspections around the work.

FAQ
As accurate as the information behind it. A structural alterations figure given over the phone for an Amersham home will move; one written after we have looked carefully at the HP6 property usually does not. GS Renovation allows for the making good that 1930s and interwar construction demands, and shows the Buckinghamshire Council element separately. That is why our Amersham quotations tend to hold. Ring 07472 424 226 to book the free survey at your HP6 address. As a rough guide, structural alterations in London ranges from roughly £1,500 for a simple opening to £15,000 or more where underpinning or major works are involved (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Not for the structure itself. The adopted Chiltern District Local Plan is aimed at what the building does externally, so an internal alteration that changes nothing outside is a building regulations matter. Buckinghamshire Council requires a full plans application for extensive internal structural alterations to any building. Planning policy re-enters the moment the work reaches a window, a roofline or the footprint, and a listed building is a separate case entirely.
Part of Whielden Street is. The council describes it as carrying the A404 to High Wycombe and forming the south western entrance to the Amersham Old Town Conservation Area, with buildings of similar character to the High Street. The 1992 boundary amendment deleted a stretch on the west side, taking in Whielden Close, former council housing permitted in 1954. Ask Buckinghamshire Council which side of the boundary your address falls.
No. Buckinghamshire Council's list of neighbourhood plans carries no Amersham entry, so the adopted Chiltern District Local Plan and the core strategy adopted on 15 November 2011 are what your alteration is judged against. Neighbouring Chesham Bois and Little Chalfont sit at the neighbourhood area designation stage, so a property near those boundaries could be covered later. Check the council's list at the point you apply.
A structural engineer, yes. Buckinghamshire Council requires structural or architectural drawings and calculations with a full plans application, and we appoint an engineer to produce them. An architect comes in where the design itself has to be drawn up, or where a planning application has to be presented. We are the contractor. We do not produce calculations, and we are not surveyors or architects, so we appoint those who are.
