Beetham Tower, Manchester

Beetham Tower (also known as the Hilton Tower) is a landmark 47-storey mixed-use skyscraper in Manchester, England. Completed in 2006, it is named after its developers, the Beetham Organisation, and was designed by SimpsonHaugh and Partners. The development occupies a sliver of land at the top of Deansgate, hence its elongated plan and was proposed in July 2003 with construction starting a year later. At a height of 554 feet (169 m), it is the tallest building in Manchester, the 12th tallest building in the United Kingdom and the tallest building in the UK outside London. Upon opening in 2006, it was the tallest residential building in the UK and second-tallest in Europe after the Turning Torso in Malmö, Sweden at 620 feet (190 m). It has been described by the Financial Times as "the UK’s only proper skyscraper outside London".

The structure is one of the thinnest skyscrapers in the world with a height to width ratio of 12:1 on the east-west façade. A blade structure on the south side of the building acts as a façade overrun accentuating its slim form and doubles as a lightning rod. The skyscraper is visible from ten English counties on a clear day. The top-floor penthouse offers views of Greater Manchester, the Cheshire Plain, the Pennines, the Peak District and Snowdonia. The tower is known for emitting a loud unintentional hum or howl in windy weather, believed to emanate from the glass 'blade' atop the building. The hum has been recorded as a B below middle C. It can be heard over large parts of the locality.
