The Dvigatel railway wagon factory, constructed in the late 19th century (1898–1899) on a roughly 131-hectare plot of land, was one of the most important industrial facilities built in Estonia under imperial Russian rule. Not long after its establishment, the tides of history drove the factory to the edge of bankruptcy, but during the Soviet era, production was restored and reoriented towards the military industry. In 1996, the Dvigatel complex was privatised and transferred to Dvigatel AS. As most of the buildings were not used for anything significant, the owner decided to dramatically change the use of the land. Under the detailed spatial planning initiated in 2003, a new street network with utilities was envisaged for the site, and building rights were assigned to the established plots for the construction of commercial and production buildings, while taking into account the terms set for the preservation and reconstruction of protected industrial buildings. This was the first step in the development of the now thriving business park of Ülemiste City. At the time, no one really expected the region to develop as explosively as it has, nor predicted that it would rise to the status of an innovative technology hub. Today, this has led to the need to draw up new detailed spatial plans for smaller areas in the vicinity. K-Projekt has contributed to the development of the Dvigatel industrial park by preparing designs for a number of roads, streets, and utility networks.
