How stunning is this wall of doors by Dutch designer Piet Hein Eek for an Amsterdam residential project? Eek adorned the lofty foyer walls entirely with old timber doors, bathroom doors, office doors, front doors and back doors to preserve the memory of the buildings that were torn down, to make way for a residential development. The result is a draw-dropping foyer installation and a visual reminder of what once was. Via Azure Magazine. (Photos by Thomas Mayer).
