Two-storey rear extension in Gourock

Thinking about a two-storey rear extension in Gourock? A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.

Do you need planning permission for a two-storey rear extension in Gourock?

The planning route for a two-storey rear extension in Gourock is set by Scotland's householder rules and your council.

Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.

Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.

What are homes in Gourock like to extend?

Gourock has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ

Two-storey rear extension questions in Gourock

How long does a rear extension take to build in Gourock?

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

Will I need a structural engineer?

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

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.

Do you handle building control in Gourock?

Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.
