This is a big coastal development project for the historic Sevkabel factory (Siemens & Halske), situated on Vasilyevsky Island. The site is located in an industrial district, placed right between the street (Kozhewennaya linia) and the Gulf of Finland. Old red-brick 19th-century buildings of the Siemens & Halske manufactory coexist with and industrial facilities of the 70s of the 20th century on the same site. These buildings are located in different Coordinate grids of the brick and concrete buildings differ from each other, and that difference creates complex, trapezoidal spaces between them. Dealing with an existing environment, we focused our efforts on the renovation and adaptation of existing buildings, as well as on the preservation of the industrial genius loci. This approach allowed us to emphasize the existing features of the site, including some of the industrial artifacts.
