Visit a surprising and self-sustaining café in Hanoi

To have a pond, indoor waterfall and a rooftop farm in a single space is surprising. For such a space to be located in a bustling city like the Vietnamese capital, well, that’s just astonishing. But that’s what you’ll find at Koi Café, where all those elements come together in a self-sustaining ecosystem. The indoor waterfall flows into a koi pond, oxygenating the water for the fish, while waste produced by the koi goes back into a tank on the third floor. This is then recycled as natural fertiliser for the rooftop vegetable garden. A perfect marriage of form and function, Koi Café is an exciting peek into what could be a bright future for sustainable architecture.
