Casa Lleó i Morera was designed by the architect Lluís Domènech i Montaner in 1902. In fact, the project actually involved remodelling an existing building. The decoration, as was customary in modernism, draws its inspiration from curving lines and from the natural world. There are many images of members of the family, and recurring references to the surname Morera, which means mulberry tree, are also common, for example in the mulberry tree in the internal courtyard, and on the door handles. After various remodellings, at the end of the 20th century Oscar Tusquets was given the task of restoring the rest of the building. The pinnacles and the turret on top of the building were refurbished. Since 2007 the house has been part of the European Modernism Route, and it is one of the three houses which make up Barcelona’s so-called “Manzana de la Discordia”, or Block of Discord, together with Casa Amatller and Casa Batlló.
