Single-storey extensions in Forfar

Covering Forfar

Homes in Dundee and Angus

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

What do you get with a single-storey extension?

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 does a single-storey extension cost in Forfar?

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

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

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

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. Whatever the planning position, you need a building warrant from the council before any building work starts, and a completion certificate at the end.

What can change the price or programme?

Drains under the footprint may need diverting or a build-over agreement with the water company.
Kitchens and doors have long lead times, so we order them early.

Your questions answered

How long does a single-storey extension take to build?

The build itself usually takes 10 to 16 weeks once work starts on site. Design, approvals and ordering usually add 6 to 12 weeks before that.

Can we stay in the house during the build?

Usually yes. We keep the existing house closed off from the works until the knock-through near the end, and agree a temporary kitchen set-up with you if the kitchen is affected.

Who deals with the council for a project in Forfar?

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