Tucked away on a hillside, looking out to the uninhabited island it's named after, Piperi House is a minimalist dream inspired by design aesthetics in the Cycladic archipelago of which Kythnos, where this quietly brilliant home resides, is part. Four white cubes form Piperi House, linked by a mischievous series of steps - inspired by their endless counterparts in the drawings of M C Escher - which add an air of mystery to a pristine piece of architecture.
