London designer Phil Pauley came up with a futuristic concept for self-sustainable underwater living. Entitled Sub-Biosphere 2, his incredible underwater city is a viable structure “designed for aquanauts, tourism and oceanographic life sciences and long-term human, plant and animal habitation“. The project consists of eight living biomes (communities of flora and fauna) that span a site width of 340m (1105 ft), reaching their highest point at 120m (394 ft) above water.
According to Inhabitat, the underwater features include a central support biosphere that monitors life systems within its own operation facility, an observation pod, individual pods and boats, the largest measuring 20m (65 ft) in length and 20m/65 ft in height. In a constant chase for unconventional living solutions, this biosphere was designed to accommodate 100 inhabitants. Moreover, this habitat “sustains all its life support systems for air, water, food, electricity, and other resources through its innovative control of variant atmospheric pressures that occur at depth“.
