LONDON, UK – June 2025 – They say good things come in small packages—but when it comes to bifold doors, bigger is better. And no one is making a bigger splash than Bifold Door Factory, the West London glazing firm that’s quietly become a secret weapon for architects, self-builders, and even Grand Designs itself.
The company, which specialises in high-performance aluminium bifolds, is now making headlines for two very big reasons: a starring role on Channel 4’s Grand Designs, and a jaw-dropping installation at Blyth Barns that features what could be the largest bifold doors ever fitted to a British home.
From Ealing to the A-list of Architecture
Tucked away in West London, Bifold Door Factory has long been a go-to supplier for builders in the know. But 2025 has launched them into the design stratosphere.
Earlier this year, the company was handpicked to design and supply bespoke bifold systems for a stunning property featured on Channel 4’s Grand Designs. This project required precision engineering, seamless functionality, and a significant wow factor.
“We weren’t just supplying doors,” said a company spokesperson. “We were part of the design conversation—helping the architect and client turn a bold vision into a livable, light-filled masterpiece.”
The resulting episode sent curious viewers flocking to the company’s website, eager to learn more about the team behind the show’s signature glazing.
Britain’s Biggest Bifolds? See for Yourself
While the TV spotlight was a welcome surprise, Bifold Door Factory’s most ambitious recent project took place off-camera, at Blyth Barns. This countryside conversion project redefines the concept of “bringing the outside in.”
Spanning an astonishing 12 metres of continuous glazing, the company’s bespoke bifold doors at Blyth Barns may well be the largest residential installation of their kind in the UK. With a single, effortless slide, entire walls vanish into the landscape, offering sweeping views, uninterrupted light, and indoor-outdoor living at its most luxurious.
The company shared a glimpse of the installation on Instagram, where followers were stunned by both the scale and elegance of the finished product. One user summed it up perfectly:
“That’s not a bifold – it’s a game-changer.”
Built for Performance. Designed for Impact.
It’s not just about size. These doors are crafted for durability, thermal efficiency, and flawless operation. Using high-spec aluminium frames, Bifold Door Factory delivers bespoke systems that glide effortlessly, withstand harsh weather, and look like a million pounds—even if the quote wasn’t.
Every product is made to order, with in-house design support, factory-fabricated frames, and full installation available nationwide.
And unlike online resellers or anonymous drop-shippers, this is a team that works with you, not just for you.
Trusted by TV Designers, Architects & Homeowners Alike
Having earned the trust of Grand Designs producers, the company is now attracting attention from top-tier architects and luxury developers across the UK. But you don’t need to be a celebrity builder to work with them.
Their customer base ranges from first-time self-builders to experienced tradespeople who seek a supplier that arrives on time, possesses in-depth knowledge of their craft, and delivers what they promise.
“We’re proud that most of our business comes from referrals. Once people see our work, they want us for their next job.”
What’s Next?
With enquiries surging and new builds breaking ground across the country, Bifold Door Factory is expanding its team and project pipeline—but staying true to its roots: one project at a time, one client at a time, no compromises.
So, whether you’re building your dream home or just want to open up your living space to the garden, remember this: when it comes to bifolds, these are the people who open doors others
