Our Story 

Windows, redefined.

Exquisite, Handcrafted Windows & Doors

We design and manufacture award-winning bespoke windows and doors. Each and every product is handcrafted in our Biggleswade factory by the finest craftsmen who combine a passion for their craft with expert technical knowledge. As true industry pioneers, we are renowned for constantly innovating to push the limits of quality and design. Whilst innovation is at the heart of Evolution, the soul of the company is the merging of traditional handcrafted values with the very latest technological enhancements. Taking the best from the past and creating the most advanced products that help enhance and protect your home now, and for years to come.







Each of our windows and doors has its own unique journey. At Evolution, we believe there’s no substitute for real craftsmanship. For years we’ve worked with the best craftsmen, honing and developing the method and tools that make our windows and doors the pinnacle of design and technology. Our factories are filled with people, not machines. Every section of the window is put together by hand – every Georgian astragal bar, every Mock Horn – is cut and put together by an experienced team of craftsmen.

From our hands to your home, we like to make sure there’s excellence in every step.








Quality & Heritage

Our windows and doors are built to last. Beauty doesn’t have to be fleeting – durability and quality are just as important. Every single window is individually inspected and checked to make sure it reaches the high standards you deserve. Our range of designs can fit any home, old or new. If you’d like to experience the modern benefits of our technology but are concerned about being in a conservation area, let us know. We’ll be more than happy to help you apply and do the hard work for you.

With low maintenance and years of enjoyment, Evolution are effectively entrusted with part of your home. We promise at every step to live up to that trust for years to come.








Design & Innovation

Innovation and customer feedback has informed every step of our journey. We talk to our customers about their experiences with us and, more importantly, listen. At every stage of our business, we’ve made sure that our technology and design standards are at the absolute cutting edge of the industry. Our machines have been built to our own design – only we are able to make windows and doors with this technology.

With low maintenance and years of enjoyment, Evolution are effectively entrusted with part of your home. We promise at every step to live up to that trust for years to come.
