Single-storey extensions in the Lothians

Covering The Lothians

We cover the Lothians, including Livingston, Musselburgh, Bathgate and Bonnyrigg, and the towns around them.

Homes in the Lothians

Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.

What does a single-storey extension involve?

We design the extension around how you use the house: where the light comes from, how the new room joins the old one, and what happens to the drains and the garden. The structure is built in brick or block to match the house, finished with a flat roof and lantern or a pitched roof, then insulated, plastered and handed back ready to decorate.

What is the guide price for a single-storey extension in the Lothians?

Use these ranges to budget for single-storey extensions; the survey turns them into a fixed price for the agreed specification.

Single-storey extensions	Guide price incl. VAT

Good specification	£3,000 to £3,500 per m²
High specification	£3,500 to £4,000 per m²

Do you need permission for a single-storey extension in the Lothians?

Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.

Scotland has its own householder permitted development rules, and small single-storey rear extensions are often covered.

What can change the price or programme?

Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.
Kitchens and doors have long lead times, so we order them early.

What people ask before starting

Do you need to dig up the drains?

Sometimes. If a public sewer runs under the extension, the water company has to agree a build-over or a diversion. We check this at survey stage.

Will the brick match?

We source the closest available match for colour, size and texture and agree a sample panel with you before laying.
