This modular house by Michael Jantzen, simply named "M-House," is made up of hinged interchangeable steel panels that serve different functions. Certain panels are opened to reveal seating, mirrors, tables, and beds and others can be adjusted block rain. Currently one M-House has been sold to an art collector in Korea, but Jantzen is envisioning the structure to be customized for playhouses, exhibits, and even office modules.
