House Extensions in Johnstone

Johnstone is a town in Renfrewshire to the west of Paisley. It has a railway station on the line between Glasgow and Ayrshire, and the Black Cart Water runs nearby.

An extension is usually the biggest single change you can make to a house without moving. One of our closest projects to Johnstone is the open plan kitchen extension in Kilmarnock, about 15 miles away. We also work in Linwood, Houston and Bridge of Weir, close to Johnstone.

Johnstone is about 16 miles from our Kilmarnock office as the crow flies. Planning and building warrant applications for Johnstone go to Renfrewshire Council, and we deal with them for you.
