4 months before the London Olympics, a To Let sign is attached to the wall of a vacant building offering space near to the 2012 Olympic Park site. Merely a mile from the main Olympic Park site that is due to attract thousands of international interest. The 500-acre Olympic Park is the largest recreational space to open in Europe for 150 years. More than £9 billion of public money has been pumped into the area and yet some building owners with property on the periphery of the Olympic venues have left their buildings empty, hoping for last minute offers.
