I'm always on the lookout for creative shelving solutions. This one comes from a collaborative design based out of Mexico called Masiosare Studio. The Paraleelos shelves are formed by two vertical ladders that hold the horizontal cross pieces. Smaller square shelves can be placed wherever needed. Originally designed for the Estudio in San Ángel project, they are now working on mass producing the piece. More information as well as a video is available on their website.
