This house was commissioned by Joan Sans to the architect Antoni de Falguera in 1906. It is a unique building thanks to its aesthetic eclecticism. It has a maritime façade with modernist gargoyles that represent the four stations, brittle glazed ceramic and wrought iron very similar to that found in Vicenç House of Barcelona. Originally it was decorated with paintings of thematic vegetables and with two feminine figures that have not been conserved. Inside, a large part of the decorative repertoire that Antoni de Falguera has designed has been preserved. The magnificent stained-glass windows with plant elements, together with the spectacular fireplace, are absolutely modernist. In 1930, Casa Sans became the property of the Vilallonga family. Original from this epoche; the marble stair-case and the fountain with the sculpture of Diana Cazadora, by Frederic Marès.
