Map - Rashtrapati Bhavan (Rashtrapati Bhavan, Delhi)

The Rashtrapati Bhavan (, rāsh-truh-puh-ti bha-vun; ; originally Viceroy's House) is the official residence of the President of India at the western end of Rajpath, Raisina Hill, New Delhi, India. It was formerly known as Viceroy's House and constructed during the zenith of British Empire. Rashtrapati Bhavan may refer to only the 340-room main building that has the president's official residence, including reception halls, guest rooms and offices, also called the mansion; it may also refer to the entire 130-hectare (320-acre) Presidential Estate that additionally includes the presidential gardens, large open spaces, residences of bodyguards and staff, stables, other offices and utilities within its perimeter walls. In terms of area, it is the 2nd largest residence of any head of state in the world after Quirinal Palace in Italy. The other presidential homes are the Rashtrapati Nilayam in Hyderabad, Telangana and The Retreat Building in Shimla, Himachal Pradesh.

The Governor-General of India resided at Government House in Calcutta until the shift of the imperial capital to Delhi. Lord Wellesley, who is reputed to have said that ‘India should be governed from a palace, not from a country house’, ordered the construction of this grand mansion between 1799 and 1803 and in 1912, the Governor of Bengal took up residence there. The decision to build a residence in New Delhi for the British Viceroy was taken after it was decided during the Delhi Durbar in December 1911 that the capital of India would be relocated from Calcutta to Delhi. When the plan for a new city, New Delhi, adjacent to the end south of Old Delhi, was developed after the Delhi Durbar, the new palace for the Viceroy of India was given an enormous size and prominent position. About 4,000 acre of land was acquired to begin the construction of Viceroy's House, as it was originally called, and adjacent Secretariat Building between 1911 and 1916 by relocating Raisina and Malcha villages that existed there and their 300 families under the Land Acquisition Act, 1894.

The British architect Edwin Landseer Lutyens, a major member of the city-planning process, was given the primary architectural responsibility. The completed Governor-General's palace turned out very similar to the original sketches which Lutyens sent Herbert Baker, from Simla, on 14 June 1912. Lutyens' design is grandly classical overall, with colours and details inspired by Indian architecture. Lutyens and Baker, who had been assigned to work on Viceroy's House and the Secretariats, began on friendly terms. Baker had been assigned to work on the two secretariat buildings which were in front of the Viceroy's House. The original plan was to have Viceroy's House on the top of Raisina Hill, with the secretariats lower down. It was later decided to build it 400 yards back and put both buildings on top of the plateau.

Lutyens campaigned for its fixing but was not able to get it to be changed. Lutyens wanted to make a long inclined grade to Viceroy's House with retaining walls on either side. While this would give a view of the house from further back, it would also cut through the square between the secretariat buildings. The committee with Lutyens and Baker established in January 1914 said the grade was to be no steeper than 1 in 25, though it eventually was changed to 1 in 22, a steeper gradient which made it more difficult to see the Viceroy's palace. While Lutyens knew about the gradient and the possibility that the Viceroy's palace would be obscured by the road, it is thought that Lutyens did not fully realise how little the front of the house would be visible. In 1916 the Imperial Delhi committee dismissed Lutyens's proposal to alter the gradient. Lutyens thought Baker was more concerned with making money and pleasing the government, rather than making a good architectural design.

Lutyens travelled between India and England almost every year for twenty years and worked on the construction of the Viceroy's House in both countries. Lutyens reduced the building from 13000000 cuft to 8500000 cuft because of budget restrictions.

The gardens were initially designed and laid out in Mughal style by William Robert Mustoe who was influenced by Lady Hardinge who in turn had sought inspiration in the book by Constance Villiers-Stuart in her Gardens of the Great Mughals (1913). The designs underwent changes and alterations under subsequent viceroys and after Indian Independence. After independence, it was renamed as Government House.

When Chakravarti Rajagopalachari assumed office as the first Indian-born Governor General of India and became the occupant of this palace, he preferred to stay in a few rooms in the former Guest Wing, which is now the family wing of the President; he converted the then Viceroy's apartments into the Guest Wing, where visiting heads of state stay while in India.

On 26 January 1950, when Rajendra Prasad became the first President of India and occupied this building, it was renamed Rashtrapati Bhavan – the President's House.
