Regardless of your chosen Collection, all our Doors are handcrafted with meticulous attention to detail. Both Collections redefine the standards of elegance, making a bold statement in any architectural setting.

Large expanses of glass, ultra-slim profile…

Complementing the rest of the Origin Home Collection, our bi-fold doors create a harmonious look with existing door and window systems – right down to the ultra-slim profiles. The large expanses of glass sit within an ultra-strong aluminium profile, and you can choose the OB-36+ (Soho Collection), the OB-49 or the OB-72 (Contemporary Collection), each with their own individual characteristics to suit different styles.

A seamless link, your way…

Creating that truly seamless link between your home and outside space is all in the threshold. We recommend a weathered threshold, which can be sunk into the floor. It leaves a minimal lip but provides a protective weathertight seal.

Non-weathered options offer a level floor finish and create a seamless transition between the inside and out. Non-weathered options are largely recommended for internal usage.

Doors that glide effortlessly…

An intelligently engineered short wheelbase carriage assembly with four wheels, manufactured from a high-grade acetal, guides the doors along the track seamlessly, enabling them to open and close with ease. It’s quality you can see, feel and admire.

Inspired By Colour

You might be perfectly satisfied with a contemporary black, white or grey door. Alternatively, your taste might be much more adventurous. With the Origin Bi-Fold Door, you have the choice of over 150 RAL shades, and a range of dual-colour options and woodgrain finishes.

So whether you’re looking for a bright primary shade, a candy-coloured pastel or a deep, earthy tone, Origin’s extensive colour palette can’t fail to inspire you.
