43base is a minimal home located in Tokyo, Japan, designed by Miurashin Architect + Associates. Constructed from 150mm x 150mm x 12mm L-shaped steel elements produced in a factory, the rigid frame was assembled on site using a crane. Stepped into a hill, a garage at street level is the initial point of entry. A staircase leads the residents into the first level kitchen. From the entrance to the roof-top garden, the design alternates between small and large, high and low. On the top floor a bedroom is placed to hide itself from view from the common areas below.
