Amazing Quetzalcoatl's Nest

Quetzalcoatl's Nest is a condominium in Naucalpan de Juárez, Mexico City, Mexico, shaped like the legendary flying serpent representing the Mexican deity Quetzalcoatl. Designed by Mexican architect Javier Senosiain, it has a set of 10 houses built in an area of 5,000 square metres. The area which was full of slopes and ravines with trees presented a challenge to the architect who finally came up with a serpentine design retaining 98% of green space on the ground. [Source]
