BK. Architecten took over an abandoned cathedral in the city of Zwolle, originally built in the 15th century, to repurpose the lovely space into something functional and beneficial to the public as well. An additional floor was added to create a shopping center within the structure, but the space still feels historically intact and somber, just as a cathedral, or The NYPL on its serious days, should feel. Three floors were added in the side wing of the church for greater access, but in order to keep the original structure safe, the new floors are not connected to the church, so that future demolitions might still save the cathedral building. To keep the 15th century feel, the architects were careful to use wood in only three colors and white painted plastering, so that the modern additions don't feel like they're doing battle with the original building.
