Two-storey rear extension in Clydebank

Thinking about a two-storey rear extension in Clydebank? 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.

We cover Clydebank (G60 and G81) as part of our Glasgow and the Clyde work. Two-storey rear extensions suit semi-detached houses in Clydebank best, where the extra bedroom matters as much as the bigger kitchen.

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

Here is how the rules in Scotland apply to a two-storey rear extension in Clydebank.

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 Clydebank like to extend?

Post-war semis and terraces are common around Clydebank, and many have room for a single-storey rear extension within Class 1A limits.

How a two-storey rear extension in Clydebank comes together

  1. Look round and measure

    A free visit to see the back of the house, measure it, check the drains and boundaries and hear what you need.

  2. Design and guide price

    Two or three layout options with a guide price for each, so you choose the design knowing what it costs.

  3. Planning and regulations

    We take the design through the right planning route, then produce the construction drawings and engineer's calculations for the building warrant.

  4. Written price, then build

    Once the design and approvals are in place, you get a fixed written price and programme, and we build through to sign-off.

FAQ

Two-storey rear extension questions in Clydebank

Do you handle building control in Clydebank?

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

Do I need a party wall agreement?

Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.

Is two-storey cheaper per square metre than single-storey?

Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.

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.

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.
