By task of work was to design polyfunctional gymnasium for STU near the student home Mladá garda. This object had to live up to functional demands of sports fields, which had to be effectively designed and connected. After analyzes of surrounding I tried to design the way it would fit into the environment, to be dominant, but simple at the same time at the first sight. I inspired by architecture of mentioned student home, which was designed by architect Emil Belluš. Facade elements of architecture on the gym are identical with elements used on Mladá garda, however transformed with help of modern technologies. On facade is noticable for example construction system, which is formed by ferroconcrete pillars, but also typical window grid in space of foyer and the gym. Solution of facade and service boldly influences principle of symetry which could be noticed on capacity of the gym, which is divided to three functional units. Dominant environmental capacity consists of entrance rooms, complete facility for spectators, and here is also designed playground with tribune. Another unit contents administrative hinterland, where on stage under there are rooms for sportsmen. I set in the last third capacity supplemental function such as space for airconditioning, storages and climbing wall. One of the conditions was to design an athletic tunnel about lenght 60 metres at least. That one I placed on the first underground stage, where is also situated underground parking. Although parking was not one of the demands, if we presume, that in the future STU would plan to arrange university matches, this function would be surely welcomed. Whole project is literally covered by green extensive roof. The aim is, that surface of the roof construction also makes more pleasant sight whether from surrounding block of flats, but also for train passengers. If I should sum it up, then object which I designed in functional way lives up to demands and by construction system allowes relatively simple construction. By aesthetical way is contruction simple on the first sight, whereas dynamic elements are not needed, because the gym is by the capacity itself dominanting feature of surrounding.
