Extensions in and around Bromsgrove
Our survey diary covers Bromsgrove, including B60, B61. Neighbouring towns we cover include Redditch (5 miles), Droitwich Spa (6 miles), Kidderminster (9 miles), Stourport-on-Severn (9 miles).
For homes towards West Midlands, Halesowen is around 8 miles away. Across the West Midlands, brick-built semis with long gardens are common, so single-storey and two-storey rear extensions are popular choices.
Do I need planning permission in Bromsgrove?
In England an annexe that stays part of the household and connects to the house is assessed as an extension, but its size usually takes it beyond permitted development, so a householder application describing the ancillary use is the normal route.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
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).

Common questions in Bromsgrove
Do I need building regulations approval in Bromsgrove?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How long does an annexe extension take to build in Bromsgrove?
On site, typically 16 to 24 weeks once approvals are in place. Before that, allow 10–16 weeks design and approvals.
Who do I contract with for an annexe extension in Bromsgrove?
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.
Can the annexe have its own front door?
Yes, many do, but it should still connect to the main house to stay clearly part of it.
How much does an annexe extension cost?
Our guide range is about £1,940 to £3,690 per m² including VAT. A one-bedroom annexe of about 35 m² is typically £81,000 to £102,000 at standard spec in Bromsgrove.
