In the archives of Dwell, architect Kyu Sung Woo renovated his son Wonbo's Union Square loft taking advantage of natural light and the 12 feet of vertical space — he stacked a minimal loft sleeping platform above the compact kitchen.
The space measures less than 700 square feet and is only 12.5' wide! By compacting the kitchen bathroom and bedroom in a small fraction of the space, the rest of the apartment seems spacious. My favorite element is the metal ladder-like stairs by Lapeyre Stair.
