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 does a double-storey extension involve?
Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.
- Building warrant application and completion certificate
- Foundations, steelwork, brick and block walls, roof
- Windows, insulation, plastering, electrics and plumbing

Do you need permission for a double-storey extension in Prestwick?
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.
Two-storey extensions in Scotland almost always need planning permission, and a building warrant must be granted before work starts.
What should Prestwick homeowners check first?
- Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
- The first-floor link can mean moving a bathroom or reshaping the landing.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Double-storey extensions: common questions
How long does a two-storey extension take?
Around 14 to 24 weeks on site, plus the planning period before that.
Will we need to move out?
Most people stay. The noisiest stage is when we break through into the existing first floor, which we plan for a short window.
Can you visit a house in Prestwick 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.
