What works

These concrete tree thingies that seem to be generally Brutalist have proven to be aesthetically successful over time. A combination of simple geometric features emphasizing the use of (reinforced) concrete and glass, a simple cantilevering, and a layout that manages to evoke traditional columnular layouts while at the same time offering characteristically Modernist light airy spareness.

The example shown above is the Katowice train station, demonstrating how this style is particularly effective for structures whose principal organizing element is a large, open main hall.
