The ability to detach dividing walls from fixed structural frameworks has been one of the most notable contributions of modern architecture. The moment came when Le Corbusier’s conceived the Dom-ino system, in 1914, and was brought to life in the Villa Savoye, where the structural lattice of pillars contrasted with an independent and even organic distribution of the interior partitions. The so-called open plan has been used and reinvented by architects since then for multiple scales and programs, with a flexibility that allows for the creation of large spaces with or without partitions. But one important nuisance that plagues the open plan it that is often difficult to create closed spaces when necessary, which can improve acoustic qualities and the possibility of natural light. Operable partitions serve this purpose through various mechanisms, such as sliding, folding, or wheeled panels, but they do not always facilitate the necessary conditions. Directly addressing these issues, Skyfold has developed the solution: operable walls that fold vertically and remain hidden when retracted.
