Covering Barnsley
Our survey diary covers Barnsley, including S70, S71, S75. Neighbouring towns we cover include Darton (3 miles), Rawmarsh (8 miles), Rotherham (10 miles), Sheffield (12 miles).
Just over the West Yorkshire border, South Elmsall is about 9 miles away. Homes across Yorkshire and the Humber range from back-to-back and through terraces to large suburban semis, and extension options vary with them.
Planning rules that apply in Barnsley
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.
The planning position for a specific Barnsley address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).

Your questions about a home office extension in Barnsley
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Barnsley, 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 Barnsley?
Yes. We cover Barnsley and the surrounding parts of South Yorkshire. Site visits are free and there is no obligation.
How long does a home office extension take to build in Barnsley?
On site, typically 8 to 12 weeks once approvals are in place. Before that, allow 4–10 weeks design and approvals.
How much does a home office extension cost?
Our guide range is about £1,740 to £3,200 per m² including VAT. An 11 m² standard-spec office is typically £22,000 to £28,000 in Barnsley.
Can I claim the cost against tax?
Building work on your home is not normally an allowable business expense, and claiming it can have capital gains tax effects. Speak to an accountant before assuming any tax relief.
