It is not clear how many people this structure is supposed to support, but the amount of grass, planted areas, and half a dozen trees would be nowhere near sufficient to create a “closed-functioning cycle” for the number that it would appear to be able to accommodate.
There are also a number of contradictions, for example: talk of naturally-lit internal areas, yet plants shroud a lot of the living areas (and the photovoltaic panels, which seem to be the new invisible models in the artist’s renders, would further block light); the structure is supposed to be used in cases of disaster relief, but the need for massive excavation to house the water and energy systems is not mentioned; it’s also not clear how the massive pre-fabricated elements would be transported to disaster-affected areas; its stability in any water other than a calm lake looks very questionable; etc.
Nice pictures, and uses plenty of architectural cliches, but doesn’t really look to provide anything like a practical design for its intended purpose. It would better serve as a concept in the luxury boutique hotels category.
