What is included
- Roof windows positioned for light and ventilation
- Vaulted ceilings or flat ceilings with storage above
- Roof design matched to the existing pitch and tiles
- Insulation to current building regulations
Matching tiles is harder than it sounds. We source reclaimed or closest-match tiles where the originals are no longer made and agree samples with you before ordering.
Covering Stanley
We cover Stanley and the postcode districts DH9. The same team covers Chester-le-Street (5 miles), Consett (5 miles), Durham (8 miles), Seaham (14 miles), all within easy reach.
Just over the Tyne and Wear border, Gateshead is about 8 miles away. Across the North East, houses often have rear yards or modest gardens, so compact, well-lit single-storey extensions make the biggest difference.
Planning and approvals in Stanley
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 Stanley 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.
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).

Your questions about a pitched roof extension in Stanley
Who do I contract with for a pitched roof extension in Stanley?
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.
How long does a pitched roof extension take to build in Stanley?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Do you cover all of Stanley?
Yes. We cover Stanley and the surrounding parts of County Durham. Site visits are free and there is no obligation.
Can I have a vaulted ceiling?
Yes. A vaulted ceiling with roof windows is one of the main reasons to choose a pitched roof. It needs insulation between and under the rafters to meet the building regulations.
How much does a pitched roof extension cost?
Our guide range is about £1,680 to £3,180 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
