Designed by Sao Paulo based Studio MK27, the Toblerone House in Brazil has been shortlisted in the ‘villas’ category of the 2012 world architecture festival, and it's easy to see why. With a ground floor surrounded by retractable glass walls, and the upstairs encased in a cocoon of wood slat screens, this great example of modern architecture sits comfortably in its natural surroundings whilst still standing as a contemporary style statement.
