Aluminium Corner Bi‑fold DoorsTwo walls disappear.
A new perspective unfolds.
The Corner Bi‑fold, redefined.
Some openings connect a room to the outside. Origin Corner Bi‑fold Doors transform the entire relationship. Wrapping two sides of your home in glass, they draw light deeper into the space, widen the outlook and create a remarkable sense of freedom between inside and out.
Designed for extensions, open‑plan living spaces and architecture that deserves a less conventional response, every set is made bespoke in the UK. Choose an internal or external corner, a fixed or moving corner post, your preferred configuration, colour and finish, then create a view that feels entirely your own.
Explore the difference.
A panoramic openingCorner Bi‑foldsWith two glazed elevations meeting at a precise 90° angle, Corner Bi‑fold Doors give the view a new sense of scale. Specify a moving corner post and it travels with the doors as they fold back, leaving the corner beautifully open and the transition to the outdoors uninterrupted.
Ultra secureCorner Bi‑foldsBeautifully open when you want it to be; reassuringly secure when you do not. Origin Corner Bi‑fold Doors feature advanced multi‑point locking and robust aluminium profiles, with the OB49 and OB72 systems available with the police‑preferred Secured by Design accreditation for added peace of mind.
Thermal EfficiencyCorner Bi‑foldsExpansive glazing should never come at the expense of everyday comfort. With U‑Values as low as 0.78 W/m2K when specified with triple‑glazing, Origin Corner Bi‑fold Doors help reduce heat loss and keep the room comfortable through every season, so you can enjoy the view whatever the weather.
HardwareCorner Bi‑foldsA considered door deserves an equally considered finishing touch.

BespokeCorner Bi‑foldsA corner opening is never ordinary, so neither is an Origin Door. Every set is made to your requirements, with control over dimensions, configuration, threshold, colour, hardware and accessory finishes. The result is considered around your home from the very beginning.
Premium AluminiumCorner Bi‑foldsOrigin Corner Bi‑fold Doors are made from premium‑grade aluminium which is inherently strong, durable and light in operation. Its strength makes ambitious multi‑panel layouts possible while maintaining refined sightlines and beautiful aesthetics.
A view shaped around your home, finished in your style.
Whichever aesthetic you choose, every Origin Corner Bi‑fold Door is made in the UK with meticulous attention to detail. Each style offers a distinct way to frame two elevations as one composition, allowing the doors to feel naturally resolved within contemporary, traditional or thoughtfully blended architecture.
Colour considered across every elevation.
The right finish can soften the meeting point between glass and masonry, echo existing windows and doors, or create a crisp frame that draws the eye towards the view.
With over 150 RAL shades to choose from, Origin aluminium Corner Bi‑fold Doors can be tailored to the property and the atmosphere you want to create. For a more individual result, choose deep blacks and greys to bring definition to modern extensions. Alternatively, softer neutrals sit elegantly alongside stone or render, or heritage colours lend depth and character to more traditional settings.
The finishing touches that complete your Corner Bi‑fold Door.
From tactile lever handles to hinges, running gear and accessory finishes, every detail can be coordinated with or contrasted against the frame.
