This is a ceramic house built in Colombia by the architect Octavio Mendoza. Ceramic houses are made by sculpting the building out of clay (or using adobe blocks) then firing the building to a high heat. This basically makes the building into a single brick (or terracotta pot), impervious to water, resistant to damage from earthquakes, and comfortably cool in hot climates.
(I suspect renovations can be a bit difficult!)
