House Extensions

More Space for What Matters.
Running out of space but don’t want to leave Glasgow or the surrounding areas?
A house extension is the smart way to upgrade your home without the hassle of moving. Whether you need a bigger kitchen for family life, a dedicated dining space, or a bright open-plan area connecting your home to the garden, we design and build extensions that genuinely change how you live.
We work across Glasgow and nearby areas, handling everything from start to finish. That includes architectural drawings, planning permission, and all construction work right through to the final finish.
No chasing multiple contractors, no confusion, just a straightforward process with one team taking care of it all.

Free QuoteHouse Extensions questions
Do I need planning permission for a house extension in Bearsden or Glasgow?
Many single-storey rear extensions fall under permitted development, but Bearsden and parts of Glasgow's West End sit within conservation areas where consent is required. We check your address against East Dunbartonshire or Glasgow City planning policy before design work starts and submit the application on your behalf.
How long does a house extension take to build?
A typical single-storey extension in Glasgow takes 10-14 weeks on site once foundations are opened, with double-storey work running 16-20 weeks. Design, warrant and planning normally add 8-12 weeks before that.
Will the extension match my existing sandstone or render finish?
Yes. We source matching blonde or red sandstone, wet-dash render and slate to suit the original property so the extension reads as part of the house rather than an addition.
Do you handle building warrants and completion certificates?
We prepare the warrant drawings, structural calculations and SAP data, deal with building standards inspections and hand over the completion certificate at the end of the project.
