Extremely complex and challenging building created by the architect. Davchev was met by Cheh Plast and it was great challenge. Ventilated facade Cheh Plast filled with etalbond (ETALBOND) of ETEM, by developing a unique new technology for the curved section. Aluminum windows and curtain walls are filled with profiles of leading Belgian company REYNAERS, as in both systems have special bends and forms that deserve respect.
