Tree-ness house by architect Akihisa Hirata

Japanese architect Akihisa Hirata has completed the development of a unique building space in Tokyo's Otsuka District entitled the "tree-ness house", inspired by his love for nature. The multi-story building creates a "tangled space", a term that describes the interconnectedness of the various units making up the unique shapes. 

"a tree consists of different parts such as roots, a trunk, branches, leaves and flowers, but these parts are not totally independent," Akihisa says. "The trunk and leaves differ in appearance, but are very similar in their basic structure — their inter-relationship creates a kind of nested or layered organic structure, it is possible to create an architectural logic that creates a similar organically layered and ‘tangled’ structure. the design seeks to develop this new architectural principle, with the intention of creating a complex ecosystem connected to the city."

Akihisa Hirata focused on three elements to define the space: boxes, pleats, and plants, as described by the design team: "the arrangement of functional volumes and voids, openings, and greenery integrates and entangles the building into a single organic whole". While the building is primarily for residential units, spaces will also be available for commercial tenants on its lower levels.
