Covering Sandhurst
Our survey diary covers Sandhurst, including GU47, RG45. Nearby, we also take on projects in Crowthorne (2 miles), Bracknell (5 miles), Wokingham (5 miles), Earley (8 miles).
Yateley, in Hampshire, is roughly 2 miles from Sandhurst and also on our list. Homes across the South East range from Victorian terraces in the older town centres to large detached houses on the edges, so the right extension type varies street by street.
Will the council need to approve it?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Your questions about a wraparound extension in Sandhurst
Will my neighbours in Sandhurst be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Sandhurst?
Yes. We cover Sandhurst and the surrounding parts of Berkshire. Site visits are free and there is no obligation.
Do I need building regulations approval in Sandhurst?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
How much does a wraparound extension cost?
Our guide range is about £2,240 to £4,140 per m² including VAT. A 25 m² standard-spec wraparound typically lands around £64,000 to £81,500 in Sandhurst before design and council fees.
