Rondo 1 is an office skyscraper with a total height of 192 m located in Warsaw, Poland at Rondo ONZ. The building was designed by Larry Oltmanns[2][3] during his time as the Design Director for the London office of Skidmore, Owings & Merrill. Epstein Architecture acted as Executive Architects.[4] The general contractor was HOCHTIEF Poland. Oltmanns stated that the design was informed by three aspirations: to create 'an idealised work environment adaptable to a wide range of ways of working; to contribute to a better plan for a liveable city; and to be a symbol of Warsaw's position in a global democratic world.'[5]
Construction began in the spring of 2003; on 7 August 2004 the foundation stone was laid, and 7 March 2006 was the official opening of the building.
