World One is a , 76 floor skyscraper in Mumbai, Maharashtra, India. As of 2022, it is the tallest completed building in India, though the currently structurally topped out Piramal Aranya Arav at and the topped out Palais Royale at are both taller. It is on the site of the defunct Shrinivas Mill. The site also houses two other towers: World View and World Crest. The complex was developed by the Lodha Group. World One was being built at an estimated cost of over US $321 million. Construction began in 2011, and it was expected to be tall. As the developer failed to obtain approval from the Airports Authority of India for that height, the project was stalled for few years. Following the delay, the project was redesigned to the current height and completed. World One's architect is Pei Cobb Freed & Partners, the structural engineer is Leslie E. Robertson Associates & MEP engineer is Buro Happold Engineers. The whole project i.e. The World Towers consists of three towers. There were two construction civil contractors involved: Arabian Construction Co. and Simplex (World One), Muscovite Group (World Crest, World View). Indian Millionaires also take part of this huge tower and some own a percentage. History The Lodha Group purchased the site of the defunct Shrinivas Mill in Lower Parel, Mumbai from Shrinivas Cotton in 2005. In June 2010, The Economic Times reported that the Lodha Group had secured over from Singapore funds GIC and Temasek, and a property fund of mortgage giant HDFC, and intended to develop property on the Shrinivas Mill site. In 2010, the developer announced the project to construct the World One tower at the site of the defunct mill. The Lodha Group would also construct the World View tower and the World Crest tower, on the same site, as part of the project. World One initially faced opposition from the Directorate General of Civil Aviation (DGCA) over security concerns related to the height of the building. World One was built at an estimated cost of over US$321 million. The interiors of the tower were designed by Giorgio Armani, and includes a swimming pool, gym and health club, cricket pitches and a pavilion. The 117-storey tower would have contained 290 apartments, some of which overlook the Arabian Sea. The contract to construct World One was awarded to a joint venture between UAE-based Arabian Construction Company and Simplex Infrastructure.
