    Bi-fold doors are the modern way to enjoy the indoors and the outdoors, all at once. A set of bi-fold doors allows you to completely open up the back of your property, making it feel like an extension of the outdoors. We can hand make our bi-fold doors using timber, or use one of our partners to provide aluminium, meaning they are completely bespoke and will meet your exact requirements.

    Bi-fold doors, which may also be known as sliding-folding doors, are often fitted into a conservatory or extension to create a more open feel. This helps to give your property a modern, open-plan aesthetic. On a practical level, they allow you to control ventilation and circulate plenty of fresh air.

    What do our customers think?

    Why choose bi-fold doors?

    Bi-fold doors are made up of sliding panels that concertina together when opened. The doors can fold inwards or outwards – choosing an outwards folding door will help to give more space inside. The system will also contain a standard door so that you can access the building normally.

    These are the main benefits you can enjoy from a bi-fold door system:

    • More space. Opening up the doors will help to make a room feel more spacious, by connecting it with the outdoors.
    • Modern aesthetic. Bi-fold doors look clean and modern – they’re a fuss-free, contemporary design feature.
    • A sense of freedom. Leave the doors open or shut depending on how you want to use the room.
    • Natural light. Even when your doors are closed, you’ll benefit from the additional natural light.
