Usually when we talk about organic style, it involves natural materials, shapes and textures, but still roughly within the framework of four walls, a ceiling, a floor and 90 degree angles. The Nautilus, however eschews all of that in favor of a truly organic shape, from top to bottom.
When our mom used to tell us that a snail's shell is it's house, we didn't take it literally. Perhaps if we had, we'd have become a bioarchitect like The Nautilus' designer Javier Senosiain.
Completed in 2006 in Mexico City, The Nautilus is spiral shaped, the spaces becoming increasingly private as one moves through: entryway to living room, then kitchen to study, then bedroom to bathroom.
