Origin Doors

The gable window can bring the ultimate striking look to a home. Beautifully designed in symmetry and sightlines, an Origin Gable turns a home into a masterpiece.

Able to be installed into even the shallowest of roof pitches, its striking appearance can be taken even further by aligning the mullion sightlines with our bi-fold doors or sliding doors sitting below the gable, for a truly breath-taking architectural solution.

Available in the OW-80 system, there are many ways to make your window yours.

Bespoke to you…

Your home is one of the few places you can truly make your own, which is why we offer lots of different ways to make your gable windows unique to you.

  • The size of your aperture. Your installer will measure this for you.
  • ConfigurationChoose what shape of gable you need to fill your aperture.
  • Select your colour scheme, whether that's the same inside and out or different.

Made for you…

Available in four different gable shapes, all made bespoke to your needs, our gables can help you make a statement by giving you a variety of geometric shapes or accommodating the most obscure angles on a building.



This gable type is perfect for ends of a house or any building style, and can fit above our sliding or bi-fold doors for a striking ceiling-to-floor near wall of glass.

The Triangle offers you variability in your angles, allowing you to create an equilateral, isosceles or a right-angle gable. The right-angled triangle is perfect for an unevenly pitched roof or perhaps giving a room a unique corner look.

Triangle with upstands

Triangle with upstands

Like the Triangle, this gable option allows you to have a drop to accommodate more light and is perfect for properties with high ceilings, allowing you to seamlessly integrate your bi-folds or sliding doors to your gable.



Perfect for gable ends with a flat roof. This allows your window to align with your new or existing aperture whilst still maximising light. As an alternative to opting for a casement window in the same space, adding a trapezoid gable will enhance your property’s character and giving your room a unique view to the outside. Moreover, you can adjust the angles on your trapezoid window to create a window that’s uniquely yours.

Trapezoid with upstands

Trapezoid with upstands

Like the Trapezoid, this gable option allows you to have a drop to accommodate even more light as well as offering greater flexibility compared to the Triangle with upstands. This is because there are more sides, meaning the drop from the ceiling can be increased even more and expanded even wider for greater openings.
