In this month's issue of Metropolis (this month's issue isn't quite up yet) they have a little article about a fairly recent Housing project in Spain by the dutch firm MVRDV, called Mirador. Apparently a lot of the neighboring housing has been built in a neo-traditional style, the MVRDV project displays their usual creative prowess and whimsy. Check it.
The building displays it's function through exterior color, orange/red for circulation for example.
They were allowed to build higher through work with the local government and putting the courtyard in the middle of the building.
