Bi_folds Bi-Design have a lot of happy customers around Suffolk and other places in UK. When it comes to opening up a room into your garden, or creating a large living space from two smaller rooms, there is no better option than Bifold Doors. They are folding doors that can open inwards or outwards, open partially (as if a regular door) or open fully and fold away to one side, inviting your garden to join your living space. Imagine being able to open up an entire wall of your home. Most bifold door manufacturers do not offer the facility to design your own bespoke bifold door online. As we manufacture almost all of our products in-house, we can back and support all guarantees and warranties we offer as we are the manufacturers of what we are selling!
