In recent years Colquhoun's has gone through a period of restructuring. We have added timber doors and door sets to the product range and transformed a traditional trade-counter business into a specialist online retailer. We have also created unique architectural hardware and timber door showrooms, displaying the most comprehensive range of quality products you will find in the UK. Our offices and distribution centres based at Nelson Street in Glasgow, less than half a mile from the company's original site, and at The Oplex Business Centre in SE London, are utilised by architects, developers, interior designers and members of the general public - all searching for unique products and services that they are unable find elsewhere. We are proud to focus on the finest quality products manufactured here in Great Britain - manufacturers such as Samuel Heath & Sons, Frank Allart, Croft Architectural Hardware, Turnstyle Designs, Kirkpatrick, Armac Martin and Imperial Locks.
