Background: This seashell-shaped home was completed in 2006. The stone steps running along the shrubs lead to the front door, which blends into the mosaic fa?ade. Why Its Unique: Architect Javier Sensonian practices what he calls bio-architecture, a style that has led him to design buildings shaped like snakes, whales and several other creatures. The Nautilus was created to imitate a crustaceans shell, and its cavernous interior is filled with vegetation and small trees. Its not common that you would see a home of this design ascetic, Koliopoulos says. However, its very enlightening and something that we can all learn from.
