Casa Batlló - arches on the top floor :: Catenary arches on the top floor of Casa Batlló - a building designed by Gaudí in the Eixample district of Barcelona, Spain. . . The local name for the building is Casa dels ossos (House of Bones), and indeed it does have a visceral, skeletal organic quality. It was originally designed for a middle-class family and situated in a prosperous district of Barcelona.
he interior is just as alive as it appears from the street; the knobbly spine lines the staircase through flowing wall forms of scale-like surfaces. The winding and twisting exhibited in the decorative features of doors, frames, peepholes, moldings and screens are all interpretations of the natural forms that inspired Gaudí’s art nouveau style.
