Homes and walls in Swansea
We also cover Briton Ferry and Gorseinon, close to Swansea.
South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of West Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.

Approvals in Wales
Householder rules in Wales are similar to England's: in Swansea, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
