Covering Aberdare
We work in Aberdare (CF44) and the places around it, including Rhondda, Merthyr Tydfil and Tonypandy.
Homes in Mid Glamorgan
Across Wales you find valley terraces, coastal towns, rural stone houses and newer estates, so access, slopes and local materials all feature in the design.
What is a mansard loft conversion?
Mansards are a bigger structural job than other conversions because the roof is largely rebuilt. They normally need planning permission, and many councils have design guides setting the angle, materials and window style. We prepare the design to those guides and build in slate, lead and timber or approved alternatives.
- Planning and building regulations checks under Welsh rules
- Staircase, insulation and fit-out
- En-suite, electrics and fire safety
