Transform any living space with glass box extensions

Glass Box Extensions from Direct Trade Windows also referred to as Frameless Conservatories, are crafted using structural glass units and supported by glass beams and fins and can completely transform any living space, incorporating winter gardens, atriums, glass facades, balcony enclosures and glass window seats. These contemporary conservatories provide an unobstructed and transparent extension space, eradicating any visible metal supports. The construction relies on frameless segments of durable structural glass, with advanced structural capabilities, paired with laminated glass beams and fins, resulting in a structure that is entirely see-through.

Our bespoke glass structures prioritise exceptional thermal efficiency and boast minimal frames, flooding living spaces with abundant natural light. Within these frameless glass boxes, a diverse array of technical glass solutions from direct trade windows can be implemented. These solutions cater to spaces demanding high performance, with features such as heated glass serving as the primary source of warmth for the extension area. Solar control coatings ensure effective protection against solar radiation, while low maintenance coatings contribute to a decrease in upkeep and cleaning requirements for these expansive frameless glass structures that seamlessly connect to the existing building, creating practical spaces that can be enjoyed no matter the weather.

Our glass box extensions are:

  • Customisable and available in various shapes and sizes
  • Available with an extensive collection of insulated glass systems
  • Crafted from durable aluminium frames
  • Perfect for pairing with our range of Steel Look Aluminium Bifold Doors and sliding doors
  • Ideal for contemporary architectural designs

    Ryan Flynn

    Superb company. Highly recommend them. Proper engineers for design and fitting. We changed spec due to some building changes and they were clear and responsive to queries and redesign. Really trustworthy group of people from sales to design to fitting. I would use them again without hesitation. Warm regards Daniel

    Daniel Champman

    The team delivered great sliding doors at a more competitive price than other suppliers. They responded to our changing development schedule without making it an issue and have provided great aftercare as well.


    We had been severely let down by a previous supplier, but when we turned to Direct Trade Windows for help, we hit the jackpot. Helping us to transform a residential development in Hersham, they supplied us with high-quality, ultra-slim Cortizo sliding doors, complete with the bespoke sliding options that we needed. Our requirements were very specific and not readily available on the market, but Direct Trade Windows really went the extra mile to help us out, coming through with quality products and excellent service. We will definitely be using their services again.

    Nothing but praise for this outfit. It was a pleasure to work with them. It was a nerve-wracking undertaking for us, the biggest single expense to fit three large window/french door combos in our extension, yet the team made it a relatively relaxing experience with their professionalism and good humour. Thank you all so much for everything you and the whole team have done to get from the initial sale (well done Hash!) to the fun visit we made to the workshop, to the design and its multiple iterations (thank you Taz!) and finally to the installation. Thoroughly recommended.
