The Rooflight Company’s Conservation Rooflight has been specified for a loft conversion at a Victorian house in Clapham. The project required a window that would respect the spirit of the Victorian building whilst also creating an area that would be filled with light. The Rooflight Company supplied four CR15 roof windows for the project. The company says their windows were chosen as they met the two main requirements of the client’s brief; to remain sympathetic to the Victorian heritage yet still provide a contemporary roof window.
