What goes into an upward extension?

An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.

Planning and building rules in Gwent

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.

Adding a storey in Wales needs planning permission.

What should Gwent homeowners check first?

The house is exposed while the roof is off, so the sequence is planned tightly.
Neighbours’ light and privacy are the main planning tests.
