The historical experience of circular plan buildings, which usually have cores that are invisible from the outside, is inevitably adjusted to the modern age and to its demands for a change in perception and a functional disposition of spatial segments. The cylindrical shape of the Zagrebtrans office building (the shell was designed by Ivan Drvar) is not the result of tradition; we see it primarily as an unusual building gesture in the commercial zone; its partially defined structure differs from its immediate surroundings, which are dominated by weak examples of architecture and urbanism that are typical for a transitional neo-liberal milieu.
