In 1962, while the Sydney Opera House was still a mass of concrete foundations, another building went up on Sydney Harbour. It was relatively modest by comparison to its monumental neighbour, a modernist apartment block on another peninsula diagonally opposite Bennelong Point - Blue's Point Tower. That building, a 25-floor tower from internationally acclaimed architect Harry Seidler, has come to be described as the "most hated building on Sydney Harbour". Why does Utzon's vision capture our imagination and Seidler's, smaller but no less dramatic statement, repel us? This is the quintessential story of mid-century modernism, and perhaps of all architectural endeavour - brutal or beautiful? Seidler was no stranger to controversy nor to accolades. He typified the practice of mid-century modernism in Australia more than any other. From the moment he arrived in Sydney his private homes were in demand and his uniquely stylised and innovatively engineered tower blocks came to dominate city skylines all over the country. His vision and his personality cannot be ignored.
