The Trekhgornaya factory represents a typical industrial site for a large city, whose territory has been excluded from public exploitation for more than a century because of its industrial function. This factor, having positive and negative points, has become decisive in determining the posterity of the manufacture after the suppression of the industry. Among the advantages of this isolation, we can mention the conservation of the morphology of buildings, which forms a unique environment distinct from its surroundings. Then, the seal for transport makes it possible to see the territory as a resource for pedestrian connections. The main disadvantage is the hermeticism of the territory unknown by city dwellers. Consequently, we have developed a conception based on the preservation of the historical context and the accentuation of the peculiarities of the composition of this space as a whole. On the other hand, taking into account the necessity of creating a multipurpose urban environment to replace the industry, we intensified the existing building by suppressing the unsightly constructions of the end of the 20th century, regenerating the whole of the site and proposing a few new constructions in harmony with the morphology of the whole. We have also created underground car parks and technical services in regeneration areas. Following these interventions, the territory of the manufacture should become an integral part of the city, possessing a unique architectural image. The possible connection with the Krasnopresnenskaya wharf could create a new urban core that would include the TEZ-7 power station as a multipurpose cultural center.
