Inside Casa Batlló Antoni Gaudí not only redistributed the existing layout of the pre-existing building in a totally functional manner, he also decorated it from top to bottom. The architect used plaster on the walls and ceiling to give them sinuous organic shapes and combined wood and glass in the windows and doors to striking effect.
The highly original decorative details of Casa Batlló reached their maximum splendour in the first floor where the proprietors lived. The stairway in the private vestibule with references to the vertebra of an animal, a hearth featuring mushroom shapes and the main lounge with its large windows and doors decorated with coloured stained glass and a series of original wall cupboards, one of which originally contained the family chapel with liturgical objects made by Gaudí’s collaborators. In the dining room the architect personally designed all the furniture including a fascinating group of ergonomic oakwood chairs and benches.
