New Museum of London, Smithfield

The Museum of London rose from the ashes a blitz-shattered corner of the City, as part of the Barbican regeneration in the '60s and '70s. Documenting the history of the city, from prehistoric times to the modern day, it is the largest centre of urban history in the world.

We've known for a while now that the museum will be relocated to Smithfield. But the designs have just been released - and they're pretty spectacular.

Asif Khan and Stanton Williams have designed a futuristic, flexible space, that is to be topped by a dome rivalling that of the British Museum. Spiral escalors form the backbone of the space - which is only the tip of the iceberg, given the huge underground chamber.

It won't open 'til 2022 - and given the way things are going, who knows what the world will look like by then. But at least we have this to look forward to.
