Closed, it's a wall of glass. Open, it removes almost the whole wall between your room and the garden. We supply and fit bespoke aluminium bi-folds, including Origin, our best-selling range. ### Who it's for Bi-folds suit families who use the garden in good weather and want the kitchen or living area to flow straight onto a patio. They're especially popular in new extensions and kitchen renovations, and in homes with a view worth opening up to. ### When to choose bi-folds Bi-folds are the right choice when you want the widest possible clear opening. If you mostly want a big view and only open the doors occasionally, sliding doors may suit better, and we'll tell you honestly which works for your space. ### Why professional fitting matters Bi-folds carry heavy glass panels on a track. If the frame isn't perfectly level and square, panels drag, seals fail and the doors become hard to open. Our fitters have 15 years' experience setting bi-fold frames so the panels glide and seal properly.

Origin bi-fold doors on a garden annex · Origin manufacturer video The range ## Choose your version Origin bi-folds and French doors share the same models, so we can make a bi-fold into a French door set-up. We'll recommend the right one for your opening at survey. ### Contemporary bi-fold Clean, plain glazing on slim aluminium frames for a modern look and the widest view of the garden. Origin manufacturer example ### Soho bi-fold Steel-inspired grids on slim aluminium, giving the industrial steel look with aluminium's strength and low maintenance. Origin manufacturer example ### French door set-up A classic pair of opening doors, with or without side panels, using the same Origin system and finishes. Origin manufacturer example ### OB36+ Origin's 36mm sightline system, shown here with plain glazing. Available with steel-look Soho styling.

Accessories & options ## Make it yours Origin offers a wide range of accessories and options with its doors. Here are the main choices we'll go through with you. ### Signature handles Origin's Signature Knurled handle sits at the heart of a hardware range designed to match across their doors and windows. Several handle styles are available. ### Handle colours Handles are available in a choice of finishes so they can match or contrast with your frame colour. ### Traffic door A bi-fold can include a traffic door, a single leaf you open day to day without folding the whole set back. ### Threshold options Choose from different threshold heights, including low threshold options for a near-level step between inside and out. ### Dual colour frames Have one colour outside to suit the house and another inside to suit the room. ### Glazing choices Clear, obscure and specialist glass options, chosen to suit privacy, sunlight and the room behind the door. ### Styles and grids Plain Gallery glazing, steel-look Soho grids or Georgian bars, or a combination, to suit the age and style of your home. ### Seal and gasket colours Even the gaskets come in colour options so the details look right up close. ### Configurations Different panel numbers, opening directions and corner bi-fold layouts, planned around how you use the space. The cost of waiting ## What happens if you leave it A poorly chosen or badly fitted bi-fold is an expensive mistake to live with. ### Panels that drag or drop An out-of-level threshold or frame leaves panels catching on the track. Over time it puts strain on rollers and hinges. ### Water at the threshold Thresholds need correct drainage and sealing. Get it wrong and rain can track in at floor level. ### Draughts in winter Misaligned panels don't compress their seals, so the room feels cold even with the doors shut. ### Common mistakes we see - Picking too many panels, leaving lots of frame and less glass when closed. - Forgetting a traffic door for everyday in-and-out use. - Not planning the stacking side around furniture and the patio. - Ordering before the opening is finished and properly measured. Our process ## Five clear steps, start to finish - 01 ### Free written quote Send us your plans or drawings and we give you a written quote setting out the product, the brand, the finish and the fitting. No pressure to decide on the spot. - 02 ### Free survey once you go ahead When you accept your quote, we visit to take exact measurements and confirm every detail, at no cost. - 03 ### Order with a 65% deposit Once you're happy, a 65% deposit places the order with the manufacturer. Your products are made to the exact measurements taken at survey. - 04 ### Installation by our fitting team Our fitters remove the old frame, prepare the opening, install the new bi-fold doors, seal it and check it opens, closes and locks smoothly. - 05 ### Completion and handover We tidy up, walk you through operation and care, and confirm the manufacturer's guarantee. The balance is due on the day of completion, and aftercare call-outs on doors we've fitted are free. Benefits ## What you get ### Widest opening Bi-folds open almost the full width of the wall, joining inside and out. ### More light A wall of glass brings daylight deep into the room year-round. ### Slim aluminium frames Aluminium is strong enough to carry big panels with slimmer frames. ### Long-term guarantee Choose Origin bi-folds and you get a 20-year manufacturer's guarantee. ### Low maintenance No painting; powder-coated frames just need an occasional clean. ### Free aftercare Aftercare call-outs on bi-folds we've fitted are free. In detail ## Options, materials and methods Everything worth knowing before your survey, so you can make a confident decision. ### Made in England, so turnaround is quick Origin designs and manufactures its products in-house in England. Because they are made in the UK rather than shipped from abroad, we can offer quick turnaround times from order to fitting. We'll give you a realistic date with your quote. ### Truly bespoke No two openings are the same. Every Origin product is made to the exact measurements taken at your survey, in your choice of colour, glazing, handles and configuration, so it fits the opening rather than the opening being forced to fit the product. ### Panel configurations Bi-folds can be configured with panels folding all to one side, split to both sides, inward or outward. Common setups range from three panels on a smaller opening to six or more across a wide extension. We'll recommend a layout based on your opening width and how you use the space. ### Traffic doors A traffic door is a single panel that opens like a normal door, so you can let the dog out without folding back the whole set. For most households it's the most-used part of the door, so it's worth planning where it sits. ### Thresholds Thresholds range from standard weather-performance designs to lower options that sit closer to floor level. A lower threshold looks seamless but needs careful planning for drainage. We'll explain the trade-offs for your home. ### Bi-folds versus sliding doors Bi-folds give a wider clear opening. Sliding doors give bigger panes of glass and fewer frame lines when closed. If you rarely open the doors fully, sliders often make more sense. We supply and fit both, so our advice isn't steered by what we sell. ### Extensions and renovations In a new extension the opening can be built to suit the doors. In a renovation we may need to work with an existing opening or your builder may be widening one. Either way, final measurements are taken once the structure is ready. ### Smaller openings, big difference Not every home has room for a wall of bi-folds. French doors make a real difference to smaller rooms: a dining room that opens onto a patio, a bedroom with a Juliet balcony, or a garden room. When both doors are open there's no central post in the way, so the opening feels larger than its size. ### Holding doors open On exposed sites, doors left open can catch the wind. We'll talk through how the doors will be held open and how they'll be used day to day, so the hardware you choose suits the way your home works. ### Replacing timber French doors Many of the French doors we replace are timber, swollen and hard to close after years of north coast weather. Swapping to aluminium removes the painting, the sticking and the rot, while keeping the same classic look. We remove the old doors, prepare the opening and fit the new frame, making good around it. ### Before your survey To get the most from your survey, have a think about a few things beforehand: how you use the room day to day, the look you're aiming for, any colours or finishes you already like, and whether other building or decorating work is planned. Photos of styles you like are useful too. None of this is essential, as we'll guide you through every choice, but it helps us give you a precise origin bi-fold & french doors quote in a single visit. ### Paying for your project We keep payment simple and transparent. A 65% deposit is taken to order your products from the manufacturer, and the balance is due on the day of completion, once the job is finished. We don't publish prices, because every home is different. Get in touch for a quote. Your written quote will show exactly what you're paying for. ### Choosing a brand We supply and fit products from manufacturers rather than making our own, which means we can recommend what genuinely suits your home. Origin aluminium is our best seller and carries a 20-year manufacturer's guarantee. RK Steel is our steel brand for internal doors, with a fire-rated option. For front doors we supply Bel'M and Palladio. At survey we'll explain the differences in plain terms. ### Understanding the guarantee Because we don't manufacture, the guarantee on your product is the manufacturer's guarantee, and it varies by brand. Origin products carry a 20-year manufacturer's guarantee. For other brands, we'll confirm the guarantee for your specific product in writing with your quote, so there are no surprises later. ### Getting an accurate quote Every opening is different, so we don't publish prices. The fastest route to a firm figure is a free quote from your plans, followed by a free survey once you go ahead: we measure, check the condition of the opening and talk through the finish, glazing and hardware you want. You'll get a written quote listing exactly what's included before you decide anything. ### Homes we work on Our customers are mainly households: replacements in existing homes, renovations, extensions and self-builds. P Black and Son supplies products from manufacturers and fits them, so you deal with one team from first visit to final handover.
