Work is due to take place to refurbish the London Transport Museum ahead of its 50th anniversary.
The Covent Garden attraction, which will remain open throughout the project, will get a new entrance, an extra 500 square metres of space for galleries alongside environmental upgrades, including low-carbon heating.
Located inside a Victorian flower market since 1980, the Grade-II listed building welcomed 450,000 visitors last year.
Elizabeth McKay, director and CEO of London Transport Museum, said: “London’s transport story is one of the greatest innovation stories in the world and this transformation is about sharing that story in a bigger, bolder and more inspiring way than ever before.”
