In general the vertical hierarchy of the urban environment opens the lower levels of buildings and outdoor spaces to the public, but the Flederhaus by Heri & Salli changes this dramatically.
Of course, this particular project is probably unlike anything you've ever seen.
The four-storey plus attic structure takes the form of a conventional house with a pitched roof, leaving its front and back facades enclosed only by guardrails on each floor. Most compellingly, the metropolitan installation in Vienna, Austria, contains clusters of hammocks so that park-goers can climb its steps and kick back in one of these suspended day sleepers. Offering a vast view of the surrounding architecture and greenery, the Flederhaus by Heri & Salli holds around 30 separate slings.
