Covering Newtown
Alongside Newtown, we also cover Welshpool (12 miles to the north-east), Llandrindod Wells and Builth Wells.
Because Powys covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.
Homes in Powys
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 side return extension?
A side return extension builds over the narrow passage that runs beside the back of many Victorian and Edwardian terraced houses, widening the kitchen or dining room by a metre or two. It is usually combined with a glazed or part-glazed roof so the deeper room still gets daylight.
- Planning and building regulations checks under Welsh rules
- Party wall notices and surveyor liaison
- Drainage and new gully positions

Do you need permission for a side return extension in Newtown?
In Wales the planning rules, including what counts as permitted development, are set by the Welsh Government, and Welsh building regulations differ in places from England’s. We check both against your house before drawings are finalised, and handle party wall notices where needed.
Wales has its own permitted development rules, set by the Welsh Government.
What can change the price or programme?
