Solarlux Glass box Extensions

A glass box extension is more than just an architectural feature, it’s a lifestyle upgrade. With its frameless design and floor-to-ceiling glazing, it floods your interior with natural light, enhances the sense of space, and offers uninterrupted views of your garden or outdoor area. Whether you’re looking to create a stylish dining area, a peaceful reading nook, or an open-plan living space, a glass box extension adds both beauty and value to your home.

Glass box extensions for brighter, all-year round spaces

Using advanced glazing technology and thermally broken aluminium frames, the glass box extensions are fully thermally efficient, meaning they stay warm in the winter and cool in the summer. Unlike older conservatories that often became too hot or too cold, our modern glass box structures are engineered for year-round comfort.

Choose from a range of features, you can have a bespoke, highly efficient, thermally insulated glazed extension which suits the architecture of your home or commercial property and with your choice ofventilation, heating, lighting and automation will provide the perfect climate and ambience inside the glass box extension. You can watch the changing seasons in the comfort and in the warmer months open up the space to embrace the outside. 

Made with high-quality sustainable low maintenance aluminium, available in 30 RAL colours as standard or sustainable wood. We take care of every detail, from initial design consultation to final installation, ensuring a stress-free experience and a flawless finish. Depending on the size and location of the glass box extension, planning permission may not be required. We always recommend a project-specific review to confirm what’s permitted.
