The Architecture of the No.75-VILLA is derived from the subtraction of volumes. The space is formed from aggregation and subtraction of pure masses focusing on spatial experience, in which the deformed solid geometry and subtractions add up to shape a variety of voids co-responding to characteristics, demands, and designing outlooks. The perceptual and visual void spaces are formed with an emphasis on transparency and permeability, A vacuity forms in the mass and amplifies with utilizing materials. In the No.75-Villa, transparency is in the foreground and not the form.
