The Sports Hall design and the project documentation on all stages had to be worked out in a very short period of time and, moreover, there were many changes to be incorporated in the project. Some of the changes were initiated by the investor, other changes were caused by the increasing pressure on the project budget control. The basic structural concept of the Sports Hall was predetermined by the budget constraint along with the limited area for the structure itself. Choosing a modest structural design and simple architectural means of expression appeared to be a must. The basic idea of the design is the numeral motif because numbers can be considered as symbols of sports played in a hall. The numbers are connected with the large windows and their positions on the façade. The architectural design as part of the documentation for the general planning proceedings contained the numbers to be displayed on the façade along with the standard large windows. In the following stages of the documentation, it was necessary to modify the layout of the hall slightly which would have resulted in changed basic positions of the windows. As the change would have affected the original architectural design, I turned the requirements for the change in the design to my advantage and I incorporated a new visual plan into the architectural concept of the structure. The basic design was extended by non-transparent coloured panels in the places where (according to the new layout) the original location of the windows proved to be unsuitable. The panels had no ties to any changes in the layout or to any operational requirements which means that the original composition did not have to be changed. The final appearance of the exterior of the hall is a result of combination of two successive stages of the architectural design. The façade can be considered as a kind of a time-lapse document showing the course of the work on the architectural design of the hall. The front of the Sports Hall was not designed accidentally by making a sketch of it on a piece of paper or by testing or examining individual options on a computer screen or by a trial-and-error method. Besides the external appearance of the building, the layout of the interiors is no less important. The layout consists of two bays. A unified, multi-purpose bay divided into individual sports sections and a small three-storey bay with operational rooms. The structure itself consists of individual operational units of the same design but in different colours.
