The López Serrano Building was the tallest residential building in Cuba until the construction of the FOCSA in 1956. Designed by the architect Ricardo Mira in 1929, who in 1941 who also designed La Moderna Poesia bookstore on Obispo Street for the same owner, it is often compared to the Bacardi Building in Old Havana built two years before the López Serrano Building because of their similarity in massing and central tower. The congressman, senator, and presidential candidate Eduardo Chibás was living on the fourteenth-floor penthouse when he committed suicide in August 1951 on the air at CMQ Radio Station.
