Corner Doors

Aluminium corner doors are two sets of bi-fold doors that meet at a corner, so a whole corner of your extension can fold away. Open them up and the kitchen or living space flows straight onto the garden from two sides at once, with a panoramic view even when they are closed.

You can have a standard corner post, or Origin's moving corner post, which is connected to the doors and slides away as you fold them back, leaving a completely clear opening. Corners can be internal (an L-shaped opening into the garden) or external, with sets from two to more than twelve doors.

Corner openings need careful structural planning, so we work with your builder or engineer from the start. Every project starts with a free design visit, where we help you choose the configuration, colour, glazing and hardware, then take a full measure for an accurate quote. A surveyor checks every detail before anything is made, and our own fitting team installs your doors carefully and leaves your home clean.

You receive a FENSA certificate, a 10-year insurance-backed guarantee and the manufacturer's product guarantee. We supply and fit aluminium corner doors across London, Hertfordshire, Kent and Surrey. Compare them with our bi-fold doors and sliding doors, or book a free design consultation.

Corner doors: frequently asked questions

What is a moving corner post?

It is a post connected to the doors that slides away as you fold them back, so there is nothing left in the corner once the doors are open.

Which Origin systems can do corners?

Corner configurations are available on Origin's OB-49 and OB-72 bi-fold systems.

How many doors can a corner set have?

Origin corner sets range from two to more than twelve doors, depending on the size of the opening.

Do corner doors need structural work?

Yes. Removing a corner of the building means the roof or floor above must be supported, usually by a steel designed by a structural engineer. We work alongside your builder so the doors fit the finished opening exactly.

Are corner doors secure?

Origin's corner bi-fold doors are Secured by Design accredited.
