It's a real achievement to make concrete look light, and the improbable effect has been mastered by the Casa en Pocafarina in Girona, Spain. A view from anywhere around the perimeter of the residence reveals a solid cement-based structure that appears to float above the sloping site.
The illusion's success rests on an open foundation that carves its way from a driveway into a subterranean garage, left uncovered and enclosed by the reinforced hill. A heavy cross-shaped mass was then set on just four pillars, reducing its points of contact and deceiving the eye into thinking it does not touch down at all.
