Two-storey rear extension in Paisley
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design, get the approvals for and build two-storey rear extensions in Paisley and the surrounding area, with one contract from the first survey to building control sign-off.
Paisley and its postcode districts PA1, PA2 and PA3 are part of our Glasgow and the Clyde coverage. In Glasgow and the Clyde we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Paisley?
Planning for a two-storey rear extension in Paisley follows the Scottish householder rules.
In Scotland an extension of more than one storey is only permitted development (Class 1B) if no part is within 10 metres of any boundary and it is no higher than the existing house, so almost every two-storey rear extension needs planning permission and a building warrant.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Paisley like to extend?
Paisley has sandstone tenements, terraced houses and villas closer in, with post-war semis and newer estates further out. Tenement and other flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Two-storey rear extension questions in Paisley
Can you match the brick or stone on my Paisley house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Does a two-storey rear extension need planning permission?
Almost always. England and Northern Ireland allow 3 metres without an application only if at least 7 metres remains to the rear boundary; Wales and Scotland are similar or stricter.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
