The Nautilus in Mexico City was designed by architect, Javier Senosiain, taking inspiration from the actual form of a nautilus. Vibrantly colorful, the house has been constructed out of concrete and chicken wire. It is earthquake proof and requires little maintenance. Harmony seems to have been the key objective of the Nautilus with the interior seamlessly flowing into various chambers. An indoor garden lounge houses a patch of vegetation adding more to its natural ambience.
