Reventós echoes the hygienist and rationalist ideas regarding social housing that focused architectural debates in Central Europe in the 1920s. In the Masana house, he decided to place the stairs on the side of the façade so that they protrude from the plan and favour the entry of light and air in these areas. He also chooses to remove the closed inner courtyards and to make the same courtyard of the block of houses penetrate the building. The exterior shows a clear mastery of pure forms and their articulation, with a first order on the ground floor marked by a slight cornice, and the crowning of the façade with brickwork. Reventós built for the same owner the neighbouring building on Tamarit Street, where he establishes a U-shaped layout around a courtyard directly connected to the interior patio. The beveled and glazed volumes of the staircase contrast with the windows - of two types - in the houses, closed with shutters and without frames.

Located in Sants-Montjuïc district, this group of apartments is located in the southern corner of the block of houses bounded by Lleida, de l'Olivera, de la Font Honrada and Tamarit Streets. It is a group of nine residential buildings between partitions with an access portal each.

Rectangular in plan and with two floors per landing, the vertical structure of each of these buildings includes a ground floor, a mezzanine, four floors, an attic and a passable roof. All in all, these buildings stand out for being the first documented example of Barcelona's Expressionist architecture.

Each of the homes has the same compositional characteristics, giving rise to a unitary ensemble. The ground floor, completely covered with limestone slabs, opens its shops to the street through large portals topped by lintels. On the other hand, the gates that give access to the homes are framed by a kind of archivolt with a lintel that makes them deeper. The mezzanine floor is also covered with stone and topped by a colourful cornice. The rest of the plants are covered with reddish mortars that originally housed sgraffito decoration in green based on borders and geometric shapes (as can be seen in the examples preserved along De l'Olivera Street). The main characteristic of these buildings is the widespread use of rectangular windows (with the exception of some balconies on De l'Olivera Street) and, above all, the resource of placing the neighbour's staircase in visible triangular glazed tribunes from the street. The attic is finished with exposed red brick work, marking a horizontal composition that counteracts the verticality of the stands.

This group of houses owned by Josep Masana was designed by the architect Ramon Reventós i Farrarons in 1928, coinciding with the redevelopment process that that part of Poble Sec would experience following the celebration of the 1929 International Exhibition. The importance of this work lies in the use, for the first time in Catalonia, of a formal expressionist language, inspired by Central European experiences in the field of mass housing. It was built in several phases between 1929 and 1930. This work connects with the European expressionist rationalism of socialist ideology, especially with the "Hofs" of mass housing in Austria and the South of Germany.

Ramón Reventós, despite being a little-known architect, played an important role in the construction of the International Exhibition of 1929 with works such as the Venetian Towers of Maria Cristina Avenue, the Grec Theatre, the Montjuïc Funicular, the Poble Espanyol or the Miramar Hotel. In addition, he is the author of Florida Hotel at the top of Tibidabo. His work is mostly noucentista.
