In 1995, almost 90 years after it was built, the basement, ground floor and first floor of the house, covering almost 1,840m², were restored. It wasn't until 2002 that part of the building was opened to the public. Since then, as repairs have been carried out, new rooms such as the attic and the roof have been made accessible. In 2013, almost the entire site was open to the public. Details of the construction process are revealed to the most curious.
Several interpretations have been developed as to the meaning of the colours and shapes of the façades. The most pertinent is that Gaudí was inspired by the sea bed, hence the predominance of navy blue. He is said to have designed Casa Batllò as a living organism in which each element has its place and function. For some, the house is a kind of marine refuge that protects its inhabitants from the outside world. Unfortunately, Gaudí never really said much about the meaning of his work.
