Do I need planning permission in Basildon?
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Local to Basildon
Site visits are available across Basildon (SS12, SS13, SS14, SS15, SS16, SS17). The same team covers Stanford-le-Hope (3 miles), Wickford (4 miles), Billericay (4 miles), Benfleet (5 miles), all within easy reach.
The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

Common questions in Basildon
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Basildon, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Basildon?
Yes. We cover Basildon and the surrounding parts of Essex. Site visits are free and there is no obligation.
How long does a home office extension take to build in Basildon?
On site, typically 8 to 12 weeks once approvals are in place. Before that, allow 4–10 weeks design and approvals.
Is an attached office better than a garden office?
An attached office shares the house heating and broadband, adds floor area to the home, and needs no garden path in the rain. A garden building can be cheaper and quicker but is a separate structure.
How much does a home office extension cost?
Our guide range is about £1,960 to £3,600 per m² including VAT. An 11 m² standard-spec office is typically £25,000 to £31,500 in Basildon.
