is a modernist-style stately home built in 1905 and 1906 in Mollerussa. Since 1990 it has been the headquarters of the Pla d'Urgell County Council. Josep Niubó Espinet, who lived in Linyola at the beginning of the 20th century, had been thinking about building a home in Mollerussa for some time, in order to save time transporting grain carts to the train station. He decided to build the house after winning second prize in the Christmas lottery in 1904. With the prize, of 250,000 pesetas, he bought several plots of land in Mollerussa, including a plot next to the train track, where he decided to build Cal Niubó. The work began in 1905 and was completed in 1906. The building was the stately home of the Niubó family from construction until 1988, when the former owner, Flòrido Niubó, donated it to the Mollerussa City Council. In 1990 it was restored and used as the headquarters of the Pla d'Urgell County Council. An adjacent glass building has been added where other offices linked to the County Council are located.
