Here at The Pegasus Door Company, we offer bespoke outdoor glass rooms and glass box extensions, tailored to your unique requirements. As our glass rooms are manufactured according to your specific needs, we can only provide an accurate estimate of how much a new glass room will cost once we’ve understood your requirements (size, location, intended use, accessories, desired finish). We’re pleased to offer a free, no-obligation home or site survey to discuss your options – contact us today to speak with a member of our friendly team.
