City of London tall office buildings including the 600-foot (183 m), 47-storey Natwest Tower, the first skyscraper in the UK. Office space development has intensified especially in the central, northern and eastern parts, with skyscrapers including 30 St. Mary Axe ("the Gherkin"'), Leadenhall Building ("the Cheesegrater"), 20 Fenchurch Street ("the Walkie-Talkie"), the Broadgate Tower and the Heron Tower, the tallest in the City. Another skyscraper, 22 Bishopsgate, is under construction. The main residential section of the City today is the Barbican Estate, constructed between 1965 and 1976. The Museum of London is based there, as are a number of other services provided by
30 St Mary Axe giving the previous owners a clear £300 million profit. Since February 2010, Sky News has broadcast its flagship business programme, "Jeff Randall Live", from a studio in the building. In addition the top two floors of tower are now available on a private hire basis for events. Deloitte announced in April 2014 that the building was again being put up for sale, with an expected price of £550 million. The current owners could not afford to make loan repayments, citing differences in the value of the multi-currency loan and the British pound, high interest rates and general financing structure. In
