The £1bn refurbishment programme at London Heathrow Airport (LHR) in the UK will begin with the demolition of the Queen's Building at Terminal 2.
As the oldest building at the airport, the Queen's Building will be first to be demolished, in January 2010, followed by the rest of the terminal.
Terminal 2 currently serves eight million passengers, but is expected to be able to serve 20 million when refurbishment is complete in 2013.
By 2019, the new £4.8bn Terminal 2 will extend into the current Terminal 1 site, with a joint capacity of 30 million passengers.
Flights have been diverted to other terminals at the airport.
