Como los clásicos tranvías de Tennessee Williams o aquellos restaurantes convertidos de coches de ferrocarril, este increíble modo de reciclar involucra una extraña yuxtaposición y mezcla de fantasía y realidad en el corazón de Londres.

El contraste entre los aburridos barrios y el colorido metro o coche subterráneo es estupendo. Marcadamente baratos, pero a la vez de transporte, montaje, instalación notablemente costoso.

Working office spaces set up on top of a roof seem like a realistic proposition, but these offices are composed graffiti-covered tube carriages (as they say in Britain) one would expect to see rusting in a gravel lot or falling slowly apart underground. Instead, they bustle with new life and vibrant artistic rooftop activity.

Masterminded by international arts charity Village Underground, these (albeit small and narrow) avant-garde office areas are leased to creative small-business, art-related start-ups looking for something a little bit off the beaten track. The non-profit, tube-loft renters range from musicians and visual artists to theater groups and jewelry makers.

And really, why not? A subway car has strength, durability and material quality well above the average prefab home - and of course is built to human scale and equipped with heavy-duty windows, built-in doors and everything else needed to create a livable and workable interior environment.

There is some genius, too, in choosing this sort of design approach for architecture intended to draw creative types: in all likelihood, those who shy away from the spaces probably are not the kind of people they want renting them anyway. Village Underground has similarly stunning and strange spaces in other countries as well.
