La Pedrera ( Casa Mila ) - Exterior/Rooftop

The exterior of Casa Mila ( commonly referred to as La Pedrera ) presents undulating balconies that look like a series of waves. The iron-wrought balconies were designed by Josep Maria Jujol, who improvised them on the spot. Some people see the facade as a cliff-like rock with caves. During its' construction, people dubbed it a quarry, or "Pedrera" and to date, people still call the building "La Pedrera" rather than "Casa Mila". Talk about freestyle, not one single line exists in this building and it uses no load-bearing walls at all. The roof is probably the most intriguing part of La Pedrera as it features a number of surrealistic colorful chimneys.
