The issue 4/2011 of ERA21 devoted to the theme of ”Who’s  Beginning in Architecture” tries to respond the question “Who are the contemporary beginning Czech and Slovak architects?” The really colourful issue offers not only presentations of first implementations and projects, but also, e.g., the look into the library of the new generation of architects – who have not read S. M. L. XL by Koolhaas and the strip cartoon by a1architects – as if does not exist. Many thanks, Era21!
