Bi-fold Doors vs Patio Doors: Which is Right for You?

Bi-fold doors and patio doors are the two most popular choices for rear garden openings in London homes — and the right answer depends on your opening width, budget, and how you want to use the space. Here is a direct comparison.

What This Guide Covers

• Bi-fold doors: fold flat against the frame, creating a full-width opening — best for 2.4m+
• Patio doors: slide on a track, offer easier operation and lower cost — best for narrower openings
• Cost: bi-fold doors typically cost 30–50% more than equivalent patio doors
• Bi-fold doors dominate in W and SW London extensions; patio doors more common in SE and suburbs
• Both require Building Regulations sign-off — we handle this as part of our service
