Gaudi's mature works, this is a compact high-level apartment building made of stone, carved densely, intersecting straight lines and curves, both rigorous and romantic. Gaudi took full advantage of the building's design to create a Catalan-style Baroque style with the characteristics of the nineteenth century. The top facade is wavy and the circular apex is enclosed in stone. The abundant corner at the top is the mascot in the mythology, which symbolizes the scene of prosperity and richness. At the three valleys there are busts, the three patrons of Mr. Calvert's native town of Drachal. The fine iron hook in the middle is used for hanging furniture.
