The Pine by Studio.e Architecture stacks 640 square feet on a 400-square-foot footprint. That means you get 60% more living space than the building covers on your lot. For homeowners with tight backyards, that math matters.
The ground floor holds the kitchen, living room, and bathroom, with a combination washer-dryer tucked under the stairs. The entire second floor is the bedroom, and it opens onto a large covered balcony that works as a morning coffee spot, a reading nook, or just extra breathing room. A covered porch at the entry and a storage closet round out the practical details.
Two-story ADUs draw some attention from neighbors, but The Pine's proportions are modest and the design reads more like a small cottage than a looming structure. If you need a real one-bedroom unit and your lot doesn't have the square footage for a sprawling single-story, this plan makes it work vertically.
