Last month announced as the winner of the international competition for a landmark regenerative project at Sydney's Harbour, Lord Richard Rogers is facing opposition for his Barangaroo plans which are said to breach height restrictions in the area.

The Barangaroo Action Group, set up by Dr Ian Campbell has lobbied the New South Wales government for over two years since demolition plans at the site were made public. They were given a chance last night to get their views across to the architect at a public meeting hosted by Barangaroo Delivery Authority and attended by former prime minister, Paul Keating.

"We have decided it's worthy of a really serious campaign," said Campbell to the Sydney Morning Herald in advance of the meeting. "Over the past 10 years the Labor government has taken over control of planning and made themselves immune to planning regulations,'' he added.

Barangaroo includes a 230 m hotel stood on reclaimed land in Sydney Harbour and a 430,000 sq m commercial and business precinct with 30,000 sq m retail. While construction is due to commence in 2011 and complete in 2013, Rogers and the current Premier Kristina Keneally will have to address locals concerns delicately despite the forecast public benefits.

"This Barangaroo design will cement Sydney as an innovative and global city as well as the financial hub of the Asia-Pacific. The commercial and business core has been set amid extensive public places and parks, further establishing Sydney as one of the world’s most liveable cities," said Keneally.
