The Japanese architectural firm Naf Architect & Design has designed a rock-climbing wall within a home.
Situated in Tokyo, this wall is a unique way for residents to access the central courtyard, which also lets light into the home.
A series of ladders also allow residents to access the higher levels, adhering to the cuboidal structure of the house.
