Structural alterations in Monmouth

Covering Monmouth

We work in Monmouth (NP25) and the places around it, including Ross-on-Wye, Chepstow and Abergavenny.

Homes in Gwent

Housing in Wales ranges from terraced streets in the valleys and older industrial towns to stone-built homes in rural areas and modern estates around the cities.

What goes into a structural alteration?

We arrange the structural calculations, support the floors and roof above with temporary props while the wall comes out, install the steel on padstones, then encase it for fire protection and make good. Chimney breast removals and new openings in external walls follow the same process.

How much does a structural alteration cost in Monmouth?

Typical ranges for structural alterations. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Structural alterations	Guide price incl. VAT
Single load-bearing wall removal with steel	£3,000 to £7,500
Chimney breast removal with support	£1,800 to £4,500
Multiple walls or full open-plan remodel	£8,000 to £20,000

How is a structural alteration approved in Monmouth?

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.

Internal work like this does not usually need planning permission in Wales unless the building is listed. Building regulations approval is needed for the structural work.

What can change the price or programme?

The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
Pipes and cables in the wall need rerouting first.
