This original watercolor painting of the tiled roof of Batlló in Barcelona is approximately 12" x 17". It should be framed (by you) into an 18x24 standard-sized frame but could to into a 16x20 standard-sized frame if mat is cut narrower or some of the painting is hideen.
It seems that the goal of Batlló was to avoid straight lines completely and the home is meant to represent Saint George battling a dragon. Much of the façade is decorated with a mosaic made of broken ceramic tiles (trencadís) that starts in shades of golden orange moving into greenish blues, which looks just like the scales of a dragon.
Casa Batlló was designed by the famous architect Antonio Gaudi who was also commissioned to refurbish it. The building was designed for Josep Batlló, a wealthy aristocrat, as an upmarket home. Señor Batlló lived in the lower two floors with his family and the upper floors were rented out as apartments. It was built in the year 1877 and remodelled in the years 1904–1906.
