A lot of tennis courts, and football pitches are being built nowadays. Those sports are played rather outside, but during a hot summer, a rainy autumn or a cold winter roof covers are necessary. The only solution is a retractable roof in which all or a part can be moved or retracted within a short period of time so that the building can be used with the roof either open or closed. A structure with a retractable roof has many parts whose features are different than those of conventional immobile structures. Light tension-strut systems which consist of slender strings and membranes capable of carrying only tensile forces and few compressed struts seem to be appropriate for rising buildings with retractable roofs. At the same time they are environmentally friendly and sustainable. The final form of such structures is not only the result of architect’s imagination but also of outer forces. Wind and snow loads acting on the roof necessitate symmetrical forms of buildings corresponding to the natural flow of forces in the structure. Those forms are willingly accepted by people.
