Knock down and rebuild in Merthyr Tydfil

Covering Merthyr Tydfil

We work in Merthyr Tydfil (CF47) and the places around it, including Aberdare, Rhondda and Ebbw Vale.

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 is a knock down and rebuild?

We assess whether rebuilding is better value than extending and renovating, prepare the planning application for the replacement dwelling, manage the demolition notice and asbestos survey, then build the new home. The process runs much like a new build once the old house is cleared.

What will a knock down and rebuild cost?

What knock down and rebuild typically cost. These are guide ranges; the written quote for your house replaces them.

Knock down and rebuild	Guide price
Demolition and site clearance (total)	£15,000 to £35,000
Rebuild, standard specification (per m²)	£2,100 to £2,600 per m²
Rebuild, good specification (per m²)	£2,600 to £3,100 per m²
Rebuild, high specification (per m²)	£3,100 to £3,700 per m²

What approvals does a knock down and rebuild need in Wales?

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.

This needs full planning permission from your council in Wales. We prepare and submit the application and deal with the planning officer on your behalf.

What can change the price or programme?

Planning policy on replacement dwellings varies, especially in green belt and countryside.
Asbestos is common in post-war houses and must be removed by licensed contractors where required.
