The current building is the result of two extensions

The building, at no. 2, Rambla Lluch, was designed in 1929 by the architect Isidre Puig Boada and consists of three floors with V-shaped roof. It has a marked noucentista influence. In 1951, an extension, almost identical to the original, was built on the southern side, in which the design of the foyer and main staircase are particularly striking.

The Roca Radiadores Company was one of the first companies to set up in Gavà and has always been closely interlinked with the development of the town.
