A house shaped like an enormous butterfly has gone up for sale for ₹52 crore. Located on the coastline of Vouliagmeni in Greece, the 5,381sq ft house has no walls on the main floor. It is a smart home with five bedrooms, four bathrooms, a private basement, an indoor pool and an elevator that goes from one floor to another. When viewed from above, it appears exactly like a butterfly because of its curvy architecture.
