Two-storey rear extension in Mayfield

Thinking about a two-storey rear extension in Mayfield? 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 Mayfield (EH19, EH22 and EH23) as part of our Edinburgh and the Lothians work. In Edinburgh and the Lothians we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

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

Whether your two-storey rear extension in Mayfield needs a planning application depends on its size, your house and any local restrictions.

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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.

What are homes in Mayfield like to extend?

Mayfield 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.

  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. Options and costs

    We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

  3. Approvals

    Permitted development check or planning application, then building warrant drawings and structural calculations, plus a written agreement with neighbours for any shared-wall work.

  4. Build and sign-off

    We build to the approved drawings with regular updates, then hand over the accepted completion certificate and any guarantees from suppliers.

FAQ

Two-storey rear extension questions in Mayfield

How much does a two-storey rear extension cost in Mayfield?

As a guide, £1,710–£2,560 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £51,500–£77,000 at that rate. Your written price follows the survey.

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.

What is the 45-degree rule?

Many councils check that a two-storey extension does not cross a 45-degree line drawn from the nearest habitable window of the neighbouring house. We test it at the first drawing.

What postcode areas do you cover around Mayfield?

Including EH19, EH22 and EH23, and the surrounding Edinburgh and the Lothians area.

Can I live at home while the extension is built?

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Do I need a party wall agreement?

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