The WaterNest 100 is a floating habitat, constructed of 98% recyclable material and is built to exist on a large or small body of calm water.
On top of the building, lies a 60-square-meter photovoltaic array capable of generating 4 kWp. Balconies wrap around parts, as well as giant windows, and the body is made from constructed from recycled glued, laminated timber with a recycled aluminum hull.
Inside the 1,000 sq ft building, measuring 12 meters across and 4 meters high, is a sleek living space with a “sophisticated system of internal natural micro-ventilation and air conditioning.”
Another interesting thing to note; if you don't want to use this place as a living space it can be altered to function as a noffice space, lounge bar, restaurant, shop, or exhibition space.
Very cool environment. Here it is, from outside, at night
