French doors interior designs use two glazed leaves, hinged on opposite sides of the opening, meeting in the middle. Both swing open together, or one can open on its own for everyday use. They’re one of the most traditional ways to divide two rooms while still sharing light between them.

Where Interior French Doors Suit a Home

  • Living room to dining room — the classic use, letting the two spaces feel connected when both doors are open
  • Study or home office — glazed doors keep the room bright, while still closing off sound when needed
  • Between a hallway and a bright room — borrows light into a hall that would otherwise stay dark

Glazing Pattern Options

Most interior French doors use multiple small panes, divided by glazing bars, rather than one large sheet of glass. This is what gives them their traditional look. Fewer, larger panes give a more contemporary feel. Georgian bar patterns, with a grid of small rectangular panes, remain the most popular choice for period homes.

French Doors vs a Single Glazed Door

A single glazed door lets light through too, but French doors give a much wider opening when both leaves are pushed back. That makes them better suited to rooms used for entertaining, where opening the space up fully matters, not just letting light across.

Cost of Interior French Doors

Budget pairs in a standard size typically cost £150–£300 for both leaves, supply-only. Solid timber or made-to-measure pairs run higher, often £350–£700. Add £100–£250 for professional fitting, especially if the frame needs adjusting to a non-standard opening.

Frequently Asked Questions

Do interior French doors need safety glass?

Yes. UK Building Regulations require toughened or laminated safety glass in door panels, so any reputable supplier includes this as standard.

Can French doors be fitted to a standard opening?

Yes, most French door kits come in standard door-opening widths. Non-standard openings usually need a made-to-measure frame instead.

Do French doors let in more draughts than a solid door?

They can, particularly around the meeting point between the two leaves. Good quality seals and a well-fitted frame keep this to a minimum.
