Yes we do, but they are generally called glass verandas by most people.
We offer a wide range for lean to glass extensions for home and business use and they are all made to order. We offer glass verandas ranging form 6mm glass to 10.8mm depending on the size of the projection and whether you require additional elements such as side sliding glass doors or vertical blinds, etc.
We also offer a wide range of polycarbonate roof systems, again all made to measure and ready supplied in kit form for DIY installation or we can provide and installation service if required.
Many roof systems are offered on the internet but all our systems only use aluminium framework and the highest quality components, usually stainless steel.
For a price and advice simply provide us with some dimensions for the width across the wall being fixed to and the projection as well as some details about the height at the back, drainage, floor surface and so on.
A picture or 2 will provide us with nearly the information we require to assist you.
