Extensions in and around Halesowen
We cover Halesowen and the postcode districts B32, B62, B63, B64, B65, B68. Nearby, we also take on projects in Brierley Hill (4 miles), Dudley (4 miles), Stourbridge (4 miles), Smethwick (5 miles).
Just over the Worcestershire border, Bromsgrove is about 8 miles away. 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.
The planning position for a specific Halesowen 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.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions people ask about glass extensions
Do I need building regulations approval in Halesowen?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Halesowen?
Yes. We cover Halesowen and the surrounding parts of West Midlands. Site visits are free and there is no obligation.
Who do I contract with for a glass extension in Halesowen?
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.
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 Halesowen.
