The building was commissioned by Joaquim Navàs, a rich textile merchant, at a time when Reus was in full effervescence. Navàs and his wife, Pepa Blasco, entrusted Domènech i Montaner with the construction of a house-shop in one of the corners of the Plaza del Mercadal in Reus. The request had an unlimited budget, which is why it became one of the most luxurious works by the architect from Barcelona.As the second Catalan capital, Reus was one of the most bombed cities in Catalonia during the Spanish Civil War and Casa Navàs also suffered the consequences. Due to one of the bombs, the tower was destroyed in 1938, as well as a large part of the roof and some of the rooms on the second floor. After the war, most of the rooms were restored by the owners themselves; the façade, however, still has some important mutilations in the upper part such as the great coronation and the tower that gave the building an elegant and slender appearance.
