While Heron Tower is one of the buildings in the City that hasn’t yet spawned a nickname, that is perhaps because it is trying to be more modest. KPF’s other proposal is less so. The Pinnacle tower, which at 288m will be the second highest building in the country after the Shard, will cost £1 billion and will be completed in 2013. Work has just begun on the spiralling form, which has been dubbed the Helter-Skelter.
