A lifestyle unbound by preconceived ideas.
Timeless, elegant, and comfortable.

Hitoshi Saruta's inspirations take form in two brands with different concepts.

Hitoshi Saruta's style is described as 'space that is comfortable but modern and elegant, perfectly blended with a Zen mindfulness.' This style can be seen consistently in both brands.

CUBO design architects is Hitoshi Saruta's brand for clients who wish to live their life in accordance with who they really are, and pursue a lifestyle unbound by preconceived ideas. CUBO design architects is Hitoshi Saruta's casual architectural brand.

The HITOSHI SARUTA concept brings affluence, universal comfort and creativity with no boundaries for architecture. It is the international flagship brand for clients with bases across the world.

Hitoshi Saruta's philosophy is 'beautiful architecture does not change with time, rather it should become more attractive as the years pass by.'


From luxury homes, compact residences, and commercial projects, view the different concepts that express the same philosophy in both brands. We work on projects in Japan, as well as globally through our international alliances with design firms around the world.
