The original developer was Rosehaugh: it was built by a Bovis / Tarmac Construction joint venture and was the largest office development in London until the arrival of Canary Wharf in the early 1990s. The original scheme was designed by Arup Associates, Team 2, which was headed by Peter Foggo, who later left Arup to set up his own practice Peter Foggo Associates,where he completed the initial phase of works.
The perimeter of the managed estate is Bishopsgate to the east, Sun Street, Appold Street and the eastern part of Worship Street to the north, the southern part of Wilson Street to the west and Eldon Street and Liverpool Street to the south. Included in the estate are Broadgate Circle and Exchange Square.
Boundary changes which came into effect in 1994 now place the entire estate within the City of London - previously a part was in the London Borough of Hackney. It lies within the ward of Bishopsgate.
Several different companies such as British Rail have participated in the development of the estate. Between 2003 and 2009 the whole estate was owned by British Land, which has been involved since 1984. Statistics from British Land indicate that the estate provides 360,000 m2 (3,900,000 sq ft) of office, retail and leisure accommodation spread over 129,000 m2 (32 acres) and more than 30,000 people are employed there. In October 2009, British Land sold a 50% share of the estate to the Blackstone Group. In 2014, GIC agreed to acquire the 50% interest in Broadgate owned by the Blackstone Group.
The 538-foot (164 m) Broadgate Tower, the 5th-tallest building in the City after the Heron Tower, Tower 42, The Leadenhall Building and 30 St Mary Axe was completed in 2008 and has added more than 820,000 sq ft (76,000 m2) of commercial floorspace to the estate. This building stands over the railway tracks out of Liverpool Street station.
On 7 August 2010, Broadgate became host to the twice-monthly Broadgate Farmers' Market.
In the winter months Broadgate circle used to host Broadgate Ice; London's only turn up and skate rink. In November 2017, Broadgate installed their first Christmas market. 
In early 2011 there was controversy over the redevelopment of the site of a Peter Foggo building, when it was suggested by the City of London's Chief Planning Officer Peter Rees and Ken Shuttleworth that Peter Foggo would have been pleased that the building would be demolished.
