within the building were rented out for many different functions. Due to the building's location and the beauty of the facilities being rented, the rooms of Casa Batlló were in very high demand and hosted many important events for the city. Design Overview The local name for the building is Casa dels ossos (House of Bones), as it has a visceral, skeletal organic quality. The building looks very remarkable — like everything Gaudí designed, only identifiable as Modernisme or Art Nouveau in the broadest sense. The ground floor, in particular, is rather astonishing with tracery, irregular oval windows and flowing sculpted stone work. It seems that the goal of the designer was to avoid straight lines completely. Much of the façade is decorated with a mosaic made of broken ceramic tiles (trencadís) that starts in shades of golden orange moving into greenish blues. The roof is arched and was likened to the back of a dragon or dinosaur. A common theory about the building is that the rounded feature to the left of centre, terminating at the top in a turret and cross, represents the lance of Saint George (patron saint of Catalonia, Gaudí's home), which has been plunged into the back of the dragon. Loft The loft is considered to be one of the most unusual spaces. It was formerly a service area for the tenants of the different apartments in the building which contained laundry rooms and storage areas. It is known for its simplicity of shapes and its Mediterranean influence through the use of white on the walls. It contains a series of sixty catenary arches that creates a space which represents the ribcage of an animal. Some people believe that the “ribcage” design of the arches is a ribcage for the dragon's spine that is represented in the roof. Noble floor and museum The noble floor is larger than seven-hundred square meters. It is the main floor of the building. The noble floor is accessed through a private entrance hall that utilizes skylights resembling tortoise shells and vaulted walls in curving shapes. On the noble floor, there is a spacious landing with direct views to the blue tiling of the building well. On the Passeig de Gracia side is Mr. Batlló's study, a dining room, and a secluded spot for courting couples, decorated with a mushroom-shaped fireplace. The elaborate and animal-like décor continues throughout the whole
