The largest house in the world exists in India, which is known as Lakshmi Vilas. This house is so huge that Mukesh Ambani’s Antilia and Buckingham Palace in England will also pale in front of it. If we talk about its area, then it is spread over 3,04,92,000 square feet or about 700 acres. Lakshmi Niwas used to belong to the Gaekwads of Vadodara, the royal dynasty of the Maratha Ere.
