Kogane-cho area in Yokohama – used to be famous as a red-light district – is going through a transformation. This project – led by the city of Yokohama and NPO Koganecho Area Management Center – converts the disused space under the elevated railway into a gallery, cafe, studio, and a hall for artists and creators to work and present their work. Five architects worked with approximately 100 to 150 sqm (1,080 to 1,615 sqft) of land. Some inserted concrete boxes between the railway’s concrete columns while others covered the space with pitched roofs.
