Structural alterations in Dyfed

Covering Dyfed

We cover Dyfed, including Llanelli, Ammanford, Aberystwyth and Carmarthen, and the towns around them.

Homes in Dyfed

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 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.

Planning and building rules in Dyfed

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.

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 should I think about before starting?

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.

Structural alterations: common questions

How do I know if a wall is load-bearing?

We check on site and confirm with the structural engineer.

Can the steel be hidden in the ceiling?

Often it can be set within the floor depth, avoiding a downstand. The engineer confirms what is possible.

Can you visit a house in Dyfed to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
