Homes in Ayrshire

Scottish homes range from city tenements and sandstone terraces to bungalows and modern estates, and the building warrant process shapes the programme for every project.

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

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.

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

Scottish projects follow a different process from England: the council issues a building warrant before work starts and accepts a completion certificate at the end, alongside any planning permission needed. We prepare both applications.

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

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.

Questions about a single-storey extension in Irvine

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.

Will the brick match?

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

Can you visit a house in Irvine to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
