The staircase is often considered one of the most interesting and/or spectacular features of any multi-story building. Whether it’s strictly utilitarian or presented as a grand feature, they can become a main focus and attraction of the building’s interior. Right here we have the Casa C-51, designed by Spanish architecture studio Ábaton, and it’s a nice home. It’s an award-winning sustainably built house with a raw concrete central staircase, which is my favorite feature of the house. That same suspended stairs link the entry and living room with the second floor. I think it’s designed to either have you feel like you’re in a live-action MC Escher painting, feel unsure of letting small children use it, or feel like David Bowie in Labyrinth. More pictures after the break.
