Covering Stockport
Site visits are available across Stockport (M19, SK1, SK2, SK3, SK4, SK5). Nearby, we also take on projects in Hazel Grove (2 miles), Cheadle Hulme (3 miles), Denton (4 miles), Hyde (4 miles).
Just over the Cheshire border, Wilmslow is about 6 miles away. The North West has a high share of Victorian and Edwardian terraces with rear yards and outriggers, plus large areas of inter-war semis in the suburbs.
Planning rules that apply in Stockport
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 Stockport 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).
When a home office extension makes sense
- People who work from home most of the week

Common questions in Stockport
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Stockport, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Who do I contract with for a home office extension in Stockport?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do you cover all of Stockport?
Yes. We cover Stockport and the surrounding parts of Greater Manchester. Site visits are free and there is no obligation.
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 £1,760 to £3,230 per m² including VAT. An 11 m² standard-spec office is typically £22,000 to £28,500 in Stockport.
