                    The roof of the cafeteria on Troia Island covers a surface area of 800m2. 
The main design requirement for the structure was its adaptation to the surrounding buildings and wooded area. The roofing membrane covers a maximum span of 30.0m.
The structure comprises two steel masts, which are connected to each other by a main cable, and are anchored to the foundation element.
The PVC membrane is anchored at four points: At the two mast heads and at the two ground anchors.
