dontDIY's thoughtful Passive house design has won an international competition to design an ultra-low energy house to be built in Bulgaria (Image: Passive House Bulgaria)
The sloping roof, which lends the design a somewhat jaunty cross-section, is not the result of mere architectural whimsy. These have been carefully measured up in order to achieve optimal facade-to-volume and facade-to-floor area ratios (Image: Passive House Bulgaria)
The house's second floor has been designed as entirely open plan (fret not, the bathroom is downstairs) in order to optimize natural ventilation (Image: Passive House Bulgaria)

Passive House Bulgaria recently announced the winner of its international competition to design a low-energy domicile to be built in Lozen, a village very close to Sofia. The winning entry, from Bulgarian outfit dontDIY, is not only eye-catching, but also fully compliant with the rigorous, though voluntary, Passive house standard.
