The multi-generational home layout has been a popular approach to residential architecture, especially for countries in the East, and the Stairway House by Nendo is a great example that also delivers some artistic flair. Located in "a quiet residential pocket of Shinjuku," the home spans three stories and has an attention-captivating feature that is rather non-traditional.
The first floor, which is more accessible, is reserved for the older couple and their nine cats. The second and third floor is for the younger parents and their child. The Stairway House is intercepted by a vast staircase that unites all floors of the house "to prevent the two parties from feeling isolated in their respective living quarters." Concrete was used for the outside portion of the stair, while steel was used for the interior.
