About Gage Construction
A family run building company based in Larkhall, serving Lanarkshire for over 30 years.
Built on trust, one job at a time
Gage Construction was founded by Gordon Havey, a time-served builder, and is still family owned and family run today.
We started out doing extensions and small building work around Larkhall and Hamilton, and most of our work still comes from recommendation. Over three decades we have grown into a full design and build company with our own joiners, bricklayers, roofers, plumbers, electricians, plasterers and decorators, but the way we work has not changed: turn up when we say we will, do the job properly, and leave the place tidy.
Our strapline is Design • Build • Quality • Trust, and we mean every word. Design, because we can take your project from a sketch to a building warrant. Build, because we do the work ourselves rather than sub-contract it. Quality, because our name is on it. Trust, because a builder is only as good as their last job.

What makes us different
All trades under one roof
No chasing six different tradesmen. One team, one manager, one price.
Design & build
Drawings, planning, building warrants and structural calculations handled in-house or with partners we trust.
Fixed price quotes
A written quotation against an agreed specification, so you know the cost before we start.
Fully managed
A programme before we start, weekly updates while we work, and a snagging walk-round at the end.
Local and accountable
We live and work in Lanarkshire. Most of our customers are within half an hour of Larkhall.
Fully insured
Public liability and employer's liability insurance in place, with certificates available on request.
Honest, reliable, recommended
"Had a double extension done by Gordon and his team. Absolutely delighted with the job. They were extremely helpful and so hardworking and excellent at the job they were doing. Very happy with the price he gave us and I would definitely recommend this company. Hope to use them in the future. Thanks Gordon and team!"
Robert ThomsonDouble storey extension · Facebook recommendation, December 2021"Highly recommend Gordon and his team! Gordon is so helpful and really took any stress out of the process of our extension. We just love it! It's the most used room in our house now. Gordon's team are so hard working and we couldn't believe how fast the build was finished end to end. Nothing was too much to ask. We will always recommend Gage and in no doubt we will work with them again!"
Emma ThomsonHouse extension · Facebook recommendation, March 2021"Gordon and his team worked on our extension 12 months ago. We are delighted with the result. His whole team are experienced, and are more than happy to offer their advice. Deadlines always met and the inevitable snags were handled without any fuss. Can't recommend Gage Construction highly enough. Five stars!"
Michael FlanniganHouse extension · Facebook recommendation, April 2019"5 stars! Gordon and his team did a fantastic job in my house. They knocked a load bearing wall down, inserted a steel beam, plastered walls, installed my new kitchen and laid a hard wood floor throughout. The house has been transformed and I'm so happy and over the moon with the work. The team were all really nice and Gordon is a great guy! Highly recommended."
