What a cool idea! The Village Underground is a creative area for a mixed discipline of artists in London, England.
Apparently, rescued abandoned subway cars (or Underground tube train carriages) have been turned into low-rent studio spaces for artists.
There's a restored brick Victorian warehouse below them which can be used as a gallery to show of their work. The subway cars are rented for about 15 pounds a week.
I love seeing something old being re-worked into something wonderful. Great idea! It's a win/win situation.
