be let, and a further thirty were unsold in September 2008. In September 2010, the Manchester rental market had improved, and only two apartments out of 219 were unoccupied awaiting interior fit-out. Prices for an apartment ranged from £200,000 to £750,000 in 2011. In 2012 demand for apartments exceeded supply, causing bidding wars. In 2017, the second highest penthouse on floors 44, 45 and 46 was put up for sale at £3,500,000. The tower has views over the set of Coronation Street from the north and west façade. The tower also has expansive vistas over Snowdonia, the South Pennines, the Peak District, the Cheshire Plain, Liverpool Cathedral Blackpool Tower, and Jodrell Bank Observatory on a clear day. Noise during high winds The building has become known for an intermittent hum, or howling, which is heard in windy weather, emanating from the roof's glass blade, and first reported in May 2006 – just weeks after the tower opened. The skyscraper was intended to be 50 storeys high rather than 47, but wind load tests showed that it would sway too much because of its slender shape and the 'glass blade' façade overrun caused by the height reduction has been blamed for the noise. The sound has been heard from about 300 metres away. It is close to the standard musical pitch of B3 (approximately 246.94 hertz) and has been compared to a "UFO landing". The noise affected production of Coronation Street. Work to reduce or eradicate the noise took place in 2006, 2007 and 2010. Foam pads were installed in 2006, aluminium nosing in 2007 and further work done in February 2010, but attempts to eradicate the noise permanently have been unsuccessful. The architect refused to alter the building after complaints of residents of Manchester. It was suggested that the decorative glass blade could be removed to solve the problem. The humming noise occurred again during Storm Doris in February 2017, during Storm Ciara in February 2020 and during Storm Franklin in February 2022. Incidents On 11 September 2008, a pane of glass cracked, requiring the street below to be cordoned off. On 29 January 2009, a fire broke out on the 31st floor in Mario Balotelli's flat, and the tower was partially evacuated; one apartment was left uninhabitable. On 14 February 2011, Beetham Hotels Manchester Ltd went into administration. Later in the year, the hotel was sold to Cypriot businessman
