Casa Amatller, together with the adjacent Casa Batlló, designed by Gaudí, and the Casa Lleó Morera, by Domènech i Montaner, is part of the “mansana de la discòrdia” or block of discord of Barcelona, so-named because it features buildings in sharply contrasting styles. Curiously, none of these houses was newly built; all three of them are refurbishments of already existing buildings, the Casa Amatller being the first. The original building was constructed by Antoni Robert in 1875, and in 1898 the Amatller family commissioned the Catalan architect and politician Josep Puig i Cadafalch (1867-1956) to refurbish the building. The current building dates from his “rose” or modernista period, which includes buildings such as the Casa Macaya and the Casa de les Punxes, the House of Spikes.
