7, Lok Kalyan Marg (7LKM), formerly 7, Race Course Road, is the official residence and principal workplace of the Prime Minister of India.

[1][2] Situated on Lok Kalyan Marg, New Delhi, the official name of the Prime Minister's residence complex is Panchavati.

It is spread over 4.9 hectares (12 acres) of land, comprising five bungalows in Lutyens' Delhi, built in the 1980s, which are the Prime Minister's office, residency zone and security establishment, including one occupied by Special Protection Group (SPG) and another being a guest house.

[4] When a new Prime Minister is nominated his/her original house is for the time being given a security detail and the new office holder is then advised to move in the 7, LKM at the earliest possible date.

The next Prime Minister of India Lal Bahadur Shastri chose 10 Janpath as his official residence, where he stayed 1964–1966.

A 1.5-kilometre-long (0.93 mi) tunnel connects the Indian prime minister's residence to the Safdarjung Airport, where high-importance helicopters land.

Constructed beyond Kemal Atatürk Marg, Golf Course and Safdarjung Tomb and then an overground drive to surface at the helicopter hangar at the airport, work on the tunnel began in 2010 and was completed by July 2014 and Modi was the first Prime Minister to use it.

[19] Current prime minister Narendra Modi uses 5, LKM as his residence which has also been used as so by Atal Bihari Vajpayee and Rajiv Gandhi.

It is equipped for video conferencing and simultaneous translations[17] This can be modelled into 2–3 conference rooms and can also act as a banquet for a gather of 200–340 people.

The rule applies to everybody, including the national security adviser, top bureaucrats, relatives and guests (barring close family) and visitors are expected to carry an identity card.

By 2004, the Intelligence Bureau (IB) took over most of the rooms of Samrat Hotel overlooking the residence and watchtowers were erected inside Delhi Gymkhana.

[5] The residence has a power substation, and doctors and nurses from the All India Institute of Medical Sciences are on duty round the clock.

[15][20] 7 LKM also has massive, manicured lawns and has abundant gulmohar, semal and arjuna trees which homes several birds, including peacocks.

[20] On the walls are artworks loaned by the National Gallery of Modern Art (NGMA) which are often changed in consultation with the prime minister's office.
