Covering Chepstow
Chepstow sits 14 miles east of Newport, with Portishead 12 miles to the south and Monmouth 12 miles to the north.
Homes in Gwent
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 is included in a side return extension in Chepstow?
Side returns are small in area but heavy in detail: party walls, a glazed roof, and steelwork to take out the original back wall. We design the roof for light and drainage, agree the party wall process early, and keep the work tidy because access is often through the house.
- Drainage and new gully positions
- Underfloor heating ready screed if wanted
- Plastering and making good to the old house
