In 1900, the Baron de Quadras commissioned Josep Puig i Cadafalch to refurbish a residential block on Carrer Rosselló. The architect transformed the building completely, between 1902 and 1903, providing it with two distinct façades which make it particularly interesting. When viewed from the Avinguda Diagonal, the building is reminiscent of North-European palaces, with an intricately carved neo-plateresque style which highlights the noble character of the building. Here, the long, ornate balcony, with its busts of eminent medieval and Renaissance figures, floral motifs and heraldic shields, and the mansards on the upper floor, are fully in keeping with the medieval European style. Highlights include the sculptures by Eusebi Arnau and Alfons Juyol.
