    Hi, thanks for your question.

    A glass extension can certainly be used year round. I assume that the glazed space will be an addition to the living spaces (a glass extension rather than a conservatory). You will need to ensure that you use highly insulating glass to keep heat in, at IQ Glass we use double glazing with low e coatings and argon gas fillings as standard.

    If you are worried about overheating in the warmer months we would recommend a solar control coating to the glass, especially the roof. But it will depend on how much direct sunlight hits the glass as to whether this is necessary.

    See below for some project examples where a full glass box is used as part of the internal living space:

    Andover Road · More Info

    Chaldon Road · More Info

    Claremont Square · More Info

    Drax Avenue · More Info

    The Garden Room House · More Info

    Where are you based? We don't normally offer a home visit service as we find that you visiting our showroom in Amersham is a much more useful trip as you will get to see these elements in person and talk to our technical team.

    Would you like to arrange an appointment?

    Hi Anna, thanks for you question.

    If you were to create a glazed extension using a glass roof and slim framed sliding doors to one elevation (assuming the other walls of the extension were a solid structure) it would typically cost around £2500 per m2 of floor area for the glazing.

    The below extensions are examples of this type of glass extension:

    Dalston House · More Info

    Warwick Gardens · More Info

    In order to get a better idea of glazing costs please do send us the drawings when complete and we will happy to help.

    It might also be worth booking an appointment to visit our showroom and the Sky House Design Centre in Amersham to get some more design ideas.

    Hello- thank you for your question.

    Our prices are based on design, supply and install because such specialist products are involved.

    It's difficult to give an exact price as is will be dependant on your requirements, location etc. However, The doors as shown here were flush glazed on both sides and would be about £8000 each.

    Another option to achieve this look is with our slim frame sliding glass doors with bespoke structural glazing and frameless glass beams, which you can see here. The slim frame sliding glass door system works out around £1000 per m2 once installed, excluding VAT. They are a create way to open out internal living spaces with very minimal framing, floor to ceiling glass with large glass sizes available.

    If you would like a formal quotation for your project then send across any architectural drawings or a sketch of what you want with dimensions with a location, and we'd be happy to provide you with a quotation.

Turn down the noiseIt’s not just heat or cold that can be a concern. Noise from outside can also cause problems in a glass extension. One option is glass that has acoustic insulation. This works by both reflecting noise back outside, and absorbing sound.

The glass box extensionPlenty of light and glass also make it into Brady’s dream home. “I adore very modern conservatories and huge glass panes – they provide so much light and a feeling of spaciousness. Oh and, of course, as it’s my fantasy home, someone else would clean it!”

Link with glassIf you have, or have your eye on, a property that has two separate buildings, glass can prove the ideal material with which to link them. It connects the spaces without losing the sense of openness, or the novelty of having two buildings. Here, the full height of the glass and its slim frames create a strong connection with the garden – glorious when the weather is good. In the winter, a space like this could be made to feel cosier with curtains or blinds, or you could embrace the frost and revel in the fact that you’re warm and cosy.

Box it in Glass boxes allow a window on the world from several angles. In contrast to the sharp lines of this extension, the comfortable sofa and surprising parquet flooring add warmth, making this a comfortable space from which to enjoy the view on a daily basis.Check out more great glass-box extensions

Join togetherAn innovative glazed space like this could link two rooms in a new-build or elegantly join two old buildings, such as a farmhouse and nearby barn, equally well. Architecture that embraces the pauses in the flow of a building is creative and thoughtful, and results in beautifully conceived spaces such as this one.Be inspired by glass box extensions
