A&J Joinery designs, manufactures and installs bespoke timber bi-fold doors and sliding patio doors for Fulham properties — from our workshop at Arch 9, Munster Road SW6. Every set is hand-built to your exact aperture, double-glazed with our own sealed units and fitted by our own joiners. No subcontractors. Ever.
Bi-fold and patio doors are the most transformative change you can make to a Fulham Victorian terrace or Edwardian property — opening the rear of the house to garden, flooding the kitchen-diner with light and adding significant value. A&J Joinery has been making bespoke timber bi-fold and sliding patio doors for Fulham homes since 2003, with full conservation area expertise and complete planning management built into every project.
Both styles are manufactured in our Fulham workshop. Here is an honest guide to help you choose — and we'll give you our specific recommendation for your property during your free survey.
Two to six panels that fold concertina-style to stack neatly at one or both sides of the opening — giving you the maximum possible clear opening width. The panels glide on a precision top-hung or bottom-rolling track system. When fully open, the boundary between inside and outside virtually disappears. Most popular choice for Fulham's knocked-through kitchen-dining rear extensions, connecting directly to the garden.
Best for: Wider openings (2m+) · Maximum garden access · Modern open-plan layouts · Rear extensions
One or two panels glide smoothly on a precision track system — typically with one fixed panel and one or two sliding panels. A lift-and-glide mechanism allows large, heavy panels to move effortlessly with minimal effort. Cleaner, more minimal appearance than bi-fold — no folding action, no bunching. Excellent thermal performance as each panel is one large sealed unit.
Best for: Narrower or standard-height openings · Minimal aesthetics · Heritage properties · Maximum glazing area
Our first recommendation for most Fulham bi-fold and patio doors. Accoya® is an acetylated timber with a 50-year manufacturer's guarantee against rot above ground. Critically, Accoya® is 75% more dimensionally stable than conventional softwood — meaning your bi-fold panels expand and contract minimally with seasonal changes, keeping the tracking system precise and the doors gliding smoothly year-round.
Best for: All exposed Fulham elevations · Long-term low maintenance · Maximum stability of tracking system
We'll assess your aperture, structural situation and planning context during your free survey and give you our honest recommendation.
A&J Joinery manufactures bi-fold doors in any configuration from 2 to 6 panels. The right number of panels depends on your aperture width and the proportion of the opening you want to be able to open at any one time. We advise on the optimum configuration during your free survey.
Ideal for openings of 1.2m–1.8m. Both panels fold to one side. Clean and compact.
Most popular for openings of 1.8m–2.7m. Two panels fold against one. One access door option.
Ideal for openings of 2.4m–3.6m. Two panels each side or three and one. Full-width opening.
Large openings of 3.0m–4.5m. Three panels one side, two the other. Maximum impact.
Grand openings of 3.6m–5.4m. Three panels each side. Dramatic garden room or extension opening.
All configurations available with access door — one leaf that opens independently without folding the full set, for everyday garden access without operating all panels.
Aluminium bi-fold doors have become popular for modern builds, but for Fulham's Victorian and Edwardian terraces, timber is the right material — both aesthetically and practically. Here is an honest comparison:

"A&J Joinery fitted a 4-panel Accoya® bi-fold door for our rear kitchen extension in Parsons Green. The tracking system is absolutely precision — they glide effortlessly and the factory paint finish looks brand new two years on. Worth every penny over cheaper alternatives."
"We're in the Peterborough Estate conservation area. A&J managed the entire planning application for our bi-fold doors — the conservation officer raised no objections because the timber profiles were matched exactly to our existing windows. Exceptional local expertise."
"We chose sliding patio doors for our Victorian terrace in Munster Village — A&J's recommendation over bi-fold given our narrower opening. The lift-and-glide mechanism is superb and the thermal performance has noticeably reduced our heating bills. Outstanding service."
