Homes in Renfrewshire and Inverclyde

Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.

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 Renfrew

Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.

Adding a storey in Scotland needs planning permission and a building warrant.

What should I think about before starting?

Some bungalow foundations need strengthening before a storey can be added.
The house is exposed while the roof is off, so the sequence is planned tightly.
