House ExtensionsAyrshire & Glasgow
Need more space without moving? We build house extensions that fit your home and your budget — from Ayrshire towns to Glasgow suburbs.
Why homeowners choose a house extension
Families across Ayrshire and Glasgow often outgrow their kitchens or need an extra bedroom without the cost and stress of moving. A well-planned extension adds space where you already live. We talk you through options, local building rules, and details that stand up to west-coast weather — not just what looks good in a brochure.

If you are not sure whether to extend or move, a few practical signs usually point the way. A cramped kitchen, no room for a proper desk, or a growing family often mean you need more space — and extending can cost less than buying bigger when you factor in fees and disruption.
Spotting the need early helps you plan budgets, talk to your council about rules, and avoid rushed decisions. We visit across Ayrshire and Glasgow to help you see what is realistic on your plot before you spend on drawings.
- You need more living space but want to stay in the same area or school catchment.
- Your kitchen, dining, or utility layout no longer works for daily family life.
- You would rather invest in your current home than pay stamp duty, fees, and moving stress.

Frequently Asked Questions
Common questions about house extensions in Ayrshire and Glasgow, including planning, timings, and build process.
Still have questions? We're here to help!
Single Storey Extensions
A single-storey extension usually runs along the back or side of your house. It is common for bigger kitchens, utility rooms, or open-plan living. We work with your ideas and any drawings you already have.
In coastal towns like Troon and Prestwick, wind and rain can affect how we detail roofs and flashing. We build for local weather, not just what looks good in a brochure.
Two Storey Extensions
A two-storey extension adds space upstairs and downstairs in one go. It can cost more than a single-storey build but saves repeating groundwork and scaffolding later.
Structural Work
We work with engineers when you need steel beams or new foundations. Your home stays supported while we open walls and add loads safely.
Planning Permission and Building Rules
Some projects need planning permission; others sit under permitted development rules. Rules vary by council area in Ayrshire and Glasgow. We help you understand what applies to your plot before we cut a single timber.
Building standards cover fire safety, insulation, and structure. We build so your project can pass inspection and keep your insurance valid.

Building Services
An extension ties together groundwork, brick or block work, roof, joinery, and sometimes electrics and plumbing. Our building services keep those trades lined up so you are not left with gaps between stages.
Joinery Services
Inside the new shell, joinery makes the room feel finished: skirting, doors, architrave, and fitted cupboards. We match new work to the rest of your home where you want a seamless look.
Doors and Windows
New openings need the right frames and lintels. We fit timber and composite doors and windows that suit your home.
How to Get Started
