The Best of British

Great Britain has a history of manufacturing some of the worlds most Iconic products; Rolls Royce, Bently, Burberry, Twinnings, the list goes on. These great manufacturers produce some of the highest quality products in the world. Origin and their bi-fold door system is no different. 

Design and manufacture take place at their High Wycombe Headquarters. Using high-grade aluminium and the latest manufacturing processes, the Origin OB49 and OB72 are perfectly crafted, resulting in a door system that definitely puts them in the Best of British camp.

Safety First

Safety has to be paramount. With finger safe gaskets, toughened glass, magnets to hold the doors in place and low-level thresholds to reduce trips, you can rest in the knowledge that Origins doors are safe as houses.

White, grey, black and silver are the most popular colour choices but if your tastes are a little more adventerous you have over 150 colours to choose from, as well as dual colour and several woodgrain finishes. 


One of the most common questions we get asked is what are the sightline sizes? 

The OB-49 has sightlines of 110mm and the OB-72 has sightlines of 154mm. Both doors allow light to flood your home and provide a vast expanse of glass so you can enjoy the views into the garden.
