What are Internal Bifold Doors?

Bifold doors, also known as concertina doors, are a system comprising multiple panels hinged together. They are engineered to fold back against themselves, allowing the panels to neatly stack to the side when fully opened. This unique mechanism is why internal bifold doors with glass are commonly used to create large, impressive openings, seamlessly connecting rooms—like a living room to a dining area—without the space intrusion of a standard swing door.

Average Cost of Internal Bifold Doors

When researching bifold doors, understanding the price points is crucial for your project budget. Costs can vary significantly based on size (number of leaves), material, and finish.

  • Single Bifolds (£120 - £250): For smaller openings (like closets or en-suites), single bifold units offer an affordable entry point.
  • Premium Single Bifolds (£200 - £300): If you are searching for premium solutions, consider solid oak internal bifold doors and glazed options with clear, frosted or decorative glass designs.

Benefits of Installing Internal Bifold Doors

Installing internal bifold doors is a design choice that offers both functional and aesthetic rewards:

  • Maximise Usable Space: Unlike standard doors that require a wide swing arc, bifolds stack neatly to the side. When fully open, they virtually disappear, creating expansive, unobstructed walkways that make your footprint feel significantly larger.
  • Flood Rooms with Light: The large glass panels you get with glazed bifold doors allow abundant natural light to stream deep into your home. This brightens interiors and reduces the need for artificial lighting, even when the doors are closed.
  • Flexible Living (Zoning): They provide the best of both worlds—keep them closed to create cosy, private rooms (zoning), or fold them back to create a seamless "broken-plan" flow.
  • Versatile Design: Our range is available in a variety of materials and finishes, from oak to pine and multiple glazed options, making bifold doors a perfect fit for both contemporary and traditional home designs.
