What works best for Renfrewshire and Inverclyde houses?

Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.

The types we would usually look at first for a home in Renfrewshire and Inverclyde are double-storey extensions, orangery extensions and bungalow extensions, depending on the garden and how the house is laid out.

Planning and building control in Renfrewshire and Inverclyde

In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.

In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.

In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
