5.Smartvoll (Vienna)

Smartvoll is an architecture firm which plays geometric forms against the content and principles of their concepts. They believe structural design yields to beauty that not only draws attention but sustains meaning to a design over time. They believe that the design process is not a static, linear system, it's an ever-evolving flow of competing ideas that are proposed and tested simultaneously.

Smartvoll has recently received a lot of attention for their design of a private spa in Hinterbrühl, Austria, the design has been described as a 21st century temple of relaxation. Smartvoll explains that the floor plan is reminiscent of paintings by Mondrian translated into three dimensional structures. The seemingly free-standing monolithic slabs are also reminiscent of Stoneheng or Greek temple ruins.
