Planning rules that apply in Smethwick
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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.
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).
Extensions in and around Smethwick
Postcode districts we cover around Smethwick include B16, B18, B21, B66, B67, B68. The same team covers West Bromwich (2 miles), Birmingham (3 miles), Halesowen (5 miles), Wednesbury (5 miles), all within easy reach.
Bromsgrove, in Worcestershire, is roughly 12 miles from Smethwick 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.
When a porch extension makes sense
- Busy hallways with no storage
- Homes wanting better kerb appeal
- Front doors that open straight into a living room
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
