Design and approval fees for Birmingham
Guide fees for Birmingham including VAT, using our West Midlands factor of ×0.97. Council and building control charges are not included.

Our design fee only. Building control charges are set by your council (or, in England and Wales, a registered building control approver) and quoted separately.

Will the council need to approve it?
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.
The planning position for a specific Birmingham address depends on its history and any designations, which is why we check it at the first visit.
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).
Covering Birmingham
We cover Birmingham and the postcode districts B1, B2, B3, B4, B5, B19. We also work in nearby Smethwick (3 miles), West Bromwich (5 miles), Shirley (6 miles), Halesowen (7 miles).
Just over the Worcestershire border, Bromsgrove is about 12 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.

Common questions in Birmingham
Who do I contract with in Birmingham?
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 Birmingham?
Yes. We cover Birmingham and the surrounding parts of West Midlands. Site visits are free and there is no obligation.
Do I need building regulations approval in Birmingham?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Who are building control?
Either your local council’s building control team or a registered building control approver. Both inspect the work and issue the completion certificate.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
