Mira's House was the wife of the then wealthy Mira who visited Bartleau's apartment. She wanted to own a more amazing building than Bartleau's apartment, so she went to find the famous architect Gaudi and asked him to design and build it. But the cost was much higher than that of Bartleau's construction, and the Millavians spent all their huge wealth with their husbands to pay off their debts, and in the end they had to sell a part of their house for the rest of their lives. After the completion of the project, the Milavians were not satisfied, and even had many years of lawsuits with Gaudi. But in Gaudi's mind, the Milla's House was the most perfect architectural design in his life. Since this happened, Gaudi was no longer willing to build a house for private design, so the Milla's House has become the last private house designed by Gaudi. Although Mira Apartment looks very strange inside and outside, like the alien, also known as its quarry, but many people still think that Mira Apartment is the most representative of modern architecture, but also the most original building, is one of the most important buildings in the twentieth century in the world. None of the buildings are right angles, which is also the greatest feature of Gaudi's works, because Gaudi believes that - "straight lines belong to human beings, while curves belong to God".
