Homes in Mid Glamorgan
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
What does a double-storey extension involve?
A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.
- Structural engineer’s design and calculations
- Foundations, steelwork, brick and block walls, roof
- Windows, insulation, plastering, electrics and plumbing

Planning and building rules in Maesteg
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Most two-storey extensions in Wales need householder planning permission from the council.
What can change the price or programme?
- The new roof is tied into the old one, so roof tiles and ridge details need to match.
- The first-floor link can mean moving a bathroom or reshaping the landing.
