farming studio, a vietnamese architecture practice, has completed the ‘koi cafe‘ within a three-story house in hanoi, vietnam. the design concept centers around urban agriculture through the use of an aquaponics system and koi fish aquarium.

farming studio’s design facilitates a renewable resource cycle within the cafe, as the waste from the koi fish aquarium is pumped into the soil supporting the cafe’s lush green roof. after nutrients from the waste are absorbed by the vegetation, the byproduct of purified water is returned to the aquarium. the ‘closed cycle’ eliminates waste and conserves energy while also avoiding the need to use chemical stimulants to support the plant life.

the koi fish is known as the national fish of japan 



the architects used a steel frame to modify the original spatial qualities of the building. the interiors and furnishings were built using recycled wood from the original site, further contributing to the sustainability of the design. through the aquaponics systems, fresh vegetables and produce can also be grown within the cafe to ensure a continuous system of renewable resources.
