One window, about one hundred and eighty square feet … and a seven-year process of deliberating every last detail of this Seattle apartments’ design. It makes sense, in a way, since its engineer designs the interiors of (notoriously space-frugal) airplanes for a living.

The result is nothing short of an masterpiece of space-saving home engineering, with precisely calculated furniture placements, fixture choices and spatial arrangements that took Steve Sauer dozens of hours to select in almost every case.
