Heathrow has announced it will open its new Terminal 2 on June 4th 2014.

Dubbed the Queen's Terminal, it is set to serve around 20 million passengers per year and is one of the UK's largest privately-funded building projects. It was designed by Spanish architect Luis Vidal, the man behind other airports such as Madrid Barajas and Warsaw International.

Costing £2.5 billion, the development has provided jobs for approximately 35,000 people and has taken five years to build. Airlines to be based at the new site include Aer Lingus, Virgin Atlantic Little Red and Germanwings.

It will house an energy centre and cooling station, making it the airport's most sustainable terminal. Also situated in the building will be a sculpture by artist Richard Wilson.

John Holland-Kaye, Heathrow development director, commented: "Terminal 2 has been designed with the passenger at the heart. Building on the success of Terminal 5, it will bring together technology, architecture and human touches."

The terminal will be the first airport in the country to be awarded a BREEAM rating for its sustainable building design. Compared to the previous buildings at the site, it will reduce CO2 emissions by 40 per cent.
