In the period from 28 April – 26 June this year Haus am Waldsee in Berlin will house an exhibition entitled: ‘Strukturalien – Architektur als urbane Plastik’ presenting the works of J. Mayer H. from the beginning of his work until today, especially projects which have already been completed. We recommend the event with all our hearts. The most important and the best known projects by J. Mayer H. include Metropol Parasol in Sevilla, for which he was awarded the Holcim Award, 2005, Winner Europe Bronze for Sustainable Construction and Reddot Award 2012 – Best of the Bestred for Design Award 2012. We, OP ENHEIM, are very proud that we will be implementing his first project in Wrocław and the second in Poland in our tenement. Next year, we will all have an opportunity to be eye witnesses of the architecture project atrium implemented at the tenement at Plac Solny 4 in Wrocław, which is his piece of art. Yet – up until that time, we warmly recommend a trip to Haus am Waldsee in Berlin to familiarise with the remaining projects of that German architect.
