Francesca Morera i Ortiz inherited that building from her uncle, Antoni Morera i Busó, but she died before seeing the finished work. It was her son, Albert Lleó i Morera, who took charge of the house, giving it the name by which it is known today, Casa Lleó i Morera.
Lluís Domčnech i Montaner remodeled the previous building, making it a truly modernist work of art. The house’s owner commissioned him to demolish and rebuild the façade, add three galleries and stone balconies on the different floors, and to design the interior. In order to complete this modernist piece of work, the architect was surrounded by a large group of master artists and craftsmen who were renowned for their creativity, like the sculptor Eusebi Arnau, mosaicist Mario Maragliano and cabinetmaker Gaspar Homar, among others.
