Wraparound extension in Walsall: Planning Permission Guide
Your guide to wraparound extensions in Walsall — combining rear and side extensions under one project.
Based on 19 decided applications in Walsall over 36 months (18 granted, 1 refused). Limited data — treat as indicative.
Walsall has 18 conservation areas and around 171 listed buildings on the national register. No Article 4 directions are recorded for the borough, so permitted-development rights are generally intact away from conservation areas and listed buildings — but always confirm your property's designations before relying on PD. There is a small amount of green-belt land towards the borough's edges, and parts of the district fall within Environment Agency flood zones, notably along the River Tame and local brooks. Walsall is not within any Area of Outstanding Natural Beauty, National Park or World Heritage Site.

Get personalised guidanceConservation Areas & Listed Buildings
In conservation areas, the side element of a wraparound extension is not permitted development. The rear element is limited to 3 metres depth.
Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.
Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.
Check if your property is in a conservation area or has other planning constraints.
