Covering West Bromwich
Postcode districts we cover around West Bromwich include B21, B66, B67, B69, B70, B71. We also work in nearby Smethwick (2 miles), Wednesbury (3 miles), Tipton (3 miles), Dudley (4 miles).
For homes towards Staffordshire, Great Wyrley is around 10 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.
Planning rules that apply in West Bromwich
In England a single-storey side return infill is often permitted development if it stays within the height limits and is no wider than half the width of the original house. Conservation areas, listed buildings and flats always need an application, and the boundary wall usually brings in the Party Wall Act.
The planning position for a specific West Bromwich 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.
Applications are decided by the local planning authority (your district, borough or unitary council).
What is included
- Kitchen-ready shell or full finish
- Survey of the outrigger, boundary wall and drainage
- Design to keep daylight in the middle of the house
- Removal of the side wall and new steelwork
- New boundary wall or raised party wall
Light is the design problem. A side return can make the middle of the house darker if the roof is solid, so we model the daylight and usually recommend a glazed slope or a run of rooflights along the boundary edge.
