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 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 Mid Glamorgan

Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.

Adding a storey in Wales needs planning permission. We prepare the application with drawings showing how the new roofline fits the street.

What can affect an upward extension?

Some bungalow foundations need strengthening before a storey can be added.
Neighbours’ light and privacy are the main planning tests.
