Japanese design team create 'Cat Tower Mansion'

The initial idea of residential construction firm Mitsubishi Estate Residence, the Cat Tower Mansion was realized by a team led by Japanese-based architect Akiko Ishimaru, who also happens to be a cat-lover. The multi-story structure is designed to exist within the interior of a home. The "ground floor" contains the bathroom, fit with a litter box for the cat, and every other level holds its own purpose. The second floor is a garden lounge; the third is the living room; and the top level is a soft sleeping space.
