This design is an exposition of the first contest “Tree in Architecture”, organized by the Union of Architects of Russia. Summing up the results of the contest was held as part of the annual exhibition Holzhaus at the All-Russian Exhibition Center in March 2013. The exposition was supposed to contain the exhibition itself, as well as 3 pavilions – the organizers of the competition, the Union of Architects and a partner who would venture to make it. Hence – the presence of 3 levels of the tower + upper viewing platform. The well-known company NLK Domostroenie dared to make a tower. The task was not easy – in 2 weeks to develop and implement a project of a 4-storey structure, which had to be assembled in 20 hours. Thanks to the professionalism of the NLCD team, it turned out to be possible. After the exhibition, the tower was transported to Kaliningrad for permanent residence, with subsequent insulation and year-round use.
