The regeneration project is focused on the "Wembley Park" site which includes Wembley Stadium and Wembley Arena, about a mile northeast from Wembley town centre. The Original Wembley Stadium closed in October 2000 and was demolished in 2003. The new Wembley stadium was designed by a consortium including engineering consultant Mott MacDonald and built by the Australian firm Multiplex. It cost £798 million and opened in 2007. Grade II-listed Wembley Arena, now the SSE Arena, has been sensitively refurbished in keeping with its Art Deco style. In 2004, Brent Council approved a mixed use plan by Buro Happold for the development of 55 acres (223,000 m2) adjacent to the stadium, which was presented by Quintain Limited.
