Hounslow council has given the go ahead for a £75 million tower criticised by the Royal Fine Art Commission and cabe - unless the Government Office for London blocks it. The Pinnacle is a 26-storey office block topped with a viewing gallery and restaurant by Livesey O'Malley which would form a gateway to West London. The 119m- high design includes a plaza by Chiswick roundabout, 15,400m2 of offices and 120 parking spaces. If gol refuses to let Hounslow make its decision, the plans will go to public inquiry. It was lopped from 31 to 26 storeys after rfac criticism but cabe echoed the commission's findings last month.
