The London Transport Museum is to undergo a stunning refurbishment ahead of its 50th anniversary.
Located in the heart of Covent Garden, the attraction will get a new entrance, extra 500 square metres of gallery space, and other environmental upgrades, including low carbon heating.
The museum is not expected to close during the makeover project.
In April, the museum received funding from the Department of Culture, Media and Sport to restore the historic glass and steel roof of the Grade II-listed building.
The building has been located inside a Victorian flower market since 1980 and attracted some 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."
She added: "For generations, Londoners and visitors have come to the museum to explore the city and its stories through its transport system.
"As we approach our 50th anniversary, we're creating an experience that captures the energy, creativity and optimism of London itself - while opening the doors to even more people."
TfL commissioner Andy Lord said: "For more than 200 years, London's public transport has shaped the capital and improved people's lives in so many ways, from the world's first underground railway to the iconic red bus, Oyster card and the Elizabeth line.
"This city has always led the way, and public transport has been key to its economic growth and recovery.
"I'm thrilled to support the new plans that showcase our transport heritage and the future of transport in the heart of Covent Garden."
