Local to Leek
Our survey diary covers Leek, including ST13. We also work in nearby Kidsgrove (9 miles), Longton (10 miles), Stoke-on-Trent (10 miles), Newcastle-under-Lyme (11 miles).
Congleton, in Cheshire, is roughly 9 miles from Leek and also on our list. The West Midlands has a large stock of 1930s and post-war semi-detached houses, which are well suited to rear, side and over-garage extensions, plus Victorian terraces in the older inner areas.
Will the council need to approve it?
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
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.
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 glass extension in Leek
Who do I contract with for a glass extension in Leek?
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 Leek?
Yes. We cover Leek and the surrounding parts of Staffordshire. Site visits are free and there is no obligation.
Do I need building regulations approval in Leek?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Are glass extensions cold in winter?
Modern double or triple glazing with warm-edge spacers and underfloor heating keeps them comfortable. They are not as warm as a solid room, and we explain the trade-off honestly.
How much does a glass extension cost?
Our guide range is about £2,910 to £5,630 per m² including VAT, because structural glass is made to order. A 12 m² standard-spec glass extension is typically £40,500 to £51,500 in Leek.
