Enter 3way House in Tokyo, designed by Japanese studio Naf architects.
The home is built around a seven-meter-tall rock-climbing wall rising from its central courtyard. Strong-limbed residents can climb from the first floor to a roof terrace hidden behind a two-meter-tall parapet. For advocates of more traditional transportation, the home has both ladders and a staircase. The name “3way” refers to the three different modes of moving between floors.
The home was commissioned for a couple with two children, who presumably are not afraid of heights or fake rocks. The house was originally a conventional two-story structure with a flat wooden roof; Naf designed a third-level addition with a parapet.
