Structural Alterations Amersham

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.

For Amersham, on London-derived ranges a simple new opening starts from £1,500, and underpinning a single elevation typically costs £6,000 to £21,000; 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

1. Free site survey at your Amersham address and an itemised quote.
2. The engineer we appoint designs the work, and it 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.
3. Props and any trial holes first, then the opening, joists or underpinning in the engineer's sequence.
4. Building control inspects each stage before it is covered, then issues the completion certificate.

The plan your alteration is judged against

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.

Housing in Amersham

Around 7,670 homes make up Amersham on the valuation list; 22% are flats and 78% houses, and 11% date from before 1919, 21% from between the wars and 68% from after 1945. Detached houses make up 31% of homes here, and a detached house in Amersham has its own footings, so underpinning often involves no neighbour.

Permitted development rights in the built-up area

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 The direction that once covered development near Amersham train station is recorded as rescinded by Chiltern District Council on 27 March 1991.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.

Four conservation areas in one town

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.

Building control for extensive internal alterations

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.
