Murphy Construction build home extensions across Glasgow and the whole of Scotland — single storey, double storey, kitchen extensions, rear extensions, garage conversions and loft conversions.
Michael Murphy leads every extension build personally — 18 years of experience as a joiner and builder means you get someone who understands every trade involved, not just someone who manages from a distance.
Michael Murphy leads every project personally — a joiner by trade with 18 years of hands-on construction experience. Backed by a trusted network of specialist trades built up over 18 years.
All groundwork and foundation construction for your extension — strip foundations, pad foundations, or raft foundations depending on ground conditions.
Structural frame construction — timber frame, masonry or steel depending on your design. We work from your architect's drawings and coordinate with your structural engineer.
All first fix joinery and services coordination — door frames, window boards, structural timbers and M&E first fix.
All second fix joinery and finishes — doors, skirtings, architraves, and bespoke joinery elements through to a fully completed extension.
Michael started as an apprentice joiner. 18 years on the tools means he understands the craft and won't accept anything less than a proper standard of work.
Every trade we use has been vetted and proven over years of working together. No unknown subcontractors dropped on your site at the last minute.
We deliberately limit the projects we take on. Every build gets our full attention — fewer projects, higher standards, better outcomes every time.
Based in Glasgow, covering Lanarkshire, Renfrewshire, Ayrshire, Edinburgh, Stirling and all of Scotland.
