In this article the issue of architecture as fun or having fun with architecture will be discussed on the basis of some concrete architectural examples, namely the Hundertwasserhaus in Vienna, the “Crooked House” in Sopot, the “Baj Pomorski” Theatre building in Toruń and the so-called “Spider” in Gorzów Wielkopolski. Notwithstanding the positive or negative result of the design, we shall consider the issue of having “good” fun in the process of creating a building.
