Sir Edwin Lutyens and Herbert Baker, architects of great vision and mastery, designed Rashtrapati Bhavan. Sir Lutyens designed the H-shaped structure, which takes up 5 acres on a 330-acre estate. The main building is three stories high with an attic floor for storage. It has a roof covered with sheets of corrugated iron painted white. Rashtrapati Bhavan is one of the most exquisite examples of British architecture. The building was constructed between 1908 and Achyuth Kutty Koil (1906-13). It is located in South West Delhi. The foundation stone of the present presidential mansion was laid by the then viceroy of India, Lord Hardinge of Penshurst, on 15 April 1908. The building was completed within four years at a cost of £750,000 ($1.5 million). In May 1950, after independence from Britain, Jawaharlal Nehru, first prime minister of India, gave his consent for changing the name of the president's residence to "Rashtrapati Bhavan," which means "the abode of the emperor of emperors." Today, the presidential palace complex occupies a large area in South West Delhi. It includes several other important buildings such as the vice-president's house, offices of other government officials, a museum, a library, and a game park.
