The starting point for the design process was the difficult characteristics of the plot and its existing condition. In addition to two buildings – the Polish House and the building housing the main exhibition hall, the investment area also includes numerous and rich trees, which determined the approach to designing the new part of the museum. Analyzing the architecture of the existing building, subject to demolition, it is clear that the entire building, and especially the layout and shape of the rotunda body, also respected the location of the existing trees, which, due to their size and age, had been growing there for a long time and were of value that had to be preserved at that time. At the same time, the competition design task was a room on a very limited area, full of trees, functions with a large cubic capacity and complex dependencies between individual zones. Additionally, an important aspect was also the restrictions resulting from the provisions of the regulation on fire water supply and fire routes, determining the maximum spans of buildings in the context of access to the required fire route, which in this case, taking into account the possibilities of the plot, gave an area of ​​60x60m. This prosaic assumption nevertheless strongly directed the shape of the building – it somehow spilled out between the existing trees, filling the “maximum” development area.
