Single-storey extensions in Grangemouth

Covering Grangemouth

Homes in the Forth Valley

In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.

What is included in a single-storey extension in Grangemouth?

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.

How much should I budget for a single-storey extension?

What single-storey extensions typically cost. These are guide ranges; the written quote for your house replaces them.

Single-storey extensions	Guide price incl. VAT

How is a single-storey extension approved in Grangemouth?

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 should I think about before starting?

Drains under the footprint may need diverting or a build-over agreement with the water company.
Large glazed areas need to meet energy rules, which can shape the size of doors and rooflights.

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.

Who deals with the council for a project in Grangemouth?

We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
