When Tony, our company director, brought his house it included a conservatory. One of the main upgrades he made was to put a ‘proper’ roof on it. This required getting builders to form a foundation outside the conservatory, construct the necessary steel-work, remove the old plastic roof and replace it with a new traditional roof. The glass sides and floor were left as they were, but now he has a super insulated roof installed. Planning and Building Regulation approvals will often be necessary for this type of work.
