Glass extensions are a unique, modern alternative to the traditional brick style conservatory and are a contemporary solution to provide more light and space throughout your home. Full-height glazed sidewalls coupled with a wide choice of doors, including bi-fold, patio, double and single door options lets you create your perfect room. Every Castlegate glass extension is a bespoke product, tailored specifically for you and your home - from kitchen extensions, open plan living spaces and family rooms – your new glass extension can be utilised in a way that’s right for you!


Modern Grey Glass Extension Wiltshire - Castlegate Windows

Create A Versatile Living Space

Conservatories have always been an excellent way to blur the margin between home and garden, but Castlegate is taking the idea to a new level with our modern Veranda glass extension. The glazing bars in the Veranda glazed extension oversail and carry the glass with it, to form a 'cocoon' where you can sit in the garden and be protected from the worst of the elements.

Moreover, on a warm day - by using large in line sliders or bi-fold doors you then have a much bigger space to enjoy, perfect for family barbeques! With subtle choices of supporting walls, the Veranda glazed extension can be a true cross over between a conservatory and extension.


A Style To Suit Every Home...

We pride ourselves on being able to offer a range of structural glazing solutions that help to create a contemporary environment in which to live in, whilst remaining energy efficient and thermally insulating. Not only do our glass extensions let the light flood in, they allow you to merge the lines between home and garden, whilst always remaining cosy and warm even in the winter - a true room for all seasons.

The Veranda glass extension is available in a huge range of designs and configuration options to suit any home. Furthermore, you can select from a wide choice of colour finishes, door options and decorative glazing to compliment your home.
