The 42, Residential skyscraper in Kolkata, India

The 42 is a 65-storey residential skyscraper on Chowringhee Road, rising between the Tata Centre and Jeevan Sudha. Its podium has a tan facade with closely spaced vertical ribs and a light band inscribed "TATA STEEL" in blue capitals; above, the tower is a grid of blue glass windows framed by tan bands, with recessed balconies at intervals. The shaft narrows slightly toward a flat top and stands above dense green trees.

The plot once belonged to the Maharaja of Darbhanga. The tower was proposed in 2008, and work stalled for nearly two years before the building was completed in 2019. ITC Limited, owner of the adjoining Fountain Court, sued in the Calcutta High Court over lost light and air; on 19 August 2013 the court made further steps subject to the case, and on 8 May 2014 barred construction at a pace that would defeat ITC's interests. The matter remains pending.

The name refers to premises 42B on Chowringhee Road, the address the tower shares with its planned neighbour The 42@Middleton, whose entrance opens on Middleton Street. The land once belonged to the Maharaja of Darbhanga. The podium carries the blue "TATA STEEL" lettering of the adjoining Tata Centre, a landmark residents and passers-by use to locate the building.

The 42 occupies the block on Chowringhee Road between the Tata Centre and Jeevan Sudha buildings, with its entrance side facing the road. The nearest metro stop is Maidan, a short walk away, and the tower has its own on-site car parking. The 42@Middleton, the project's second tower, is entered from Middleton Street at the north-eastern part of premises 42B.

The premises once belonged to the Maharaja of Darbhanga. The tower was planned by Mani Group, Salarpuria Sattva Group, Alcove Realty and Diamond Group, and the design is credited to architect Hafeez Contractor. A second tower, The 42@Middleton, is planned on the north-eastern part of the plot, entered from Middleton Street.
