The architects and metal sculpture designers are Caliper Studios have outdone themselves with their product, Genetic Stair. The centerpiece in a duplex apartment on Manhattan, the Genetic Stair is an amazing fusion of engineering and sculpture; in particular an amazing feat considering the ridiculously complex and limiting building safety codes for construction in New York City. Developed first as a multifarious 3D model, this clean and well-suited stairway design brings a heavy touch of modernity to a simple, elegant interior space. It maybe hard to develop a sense of continuity with something so inventive in your living space, but as a useful sculptural piece it serves as an amazing achievement for Caliper Studios
