This backyard tiny house plan fits a 17'-0" × 20'-0" rectangular footprint and provides 340 square feet of living space on a single level. It is designed for a foundation and has no porch, deck or patio, so the footprint stays simple and compact. Everything is on one level, with no stairs to climb.
Inside, one main room of 15'-0" × 11'-3" serves for living and sleeping. A kitchenette of 6'-4" × 6'-4" sits alongside a 1'-11" × 6'-4" closet and a 6'-0" × 6'-4" bathroom with shower. The plan has no separate bedroom and no garage, which keeps the layout efficient for a small backyard lot. The single-room arrangement keeps circulation short and puts every function within a few steps.

How this plan was made
It was generated in AI Architectures Plan Studio from this one-line brief: “Backyard tiny house on a 17 x 20 ft rectangular footprint (340 sq ft), one story, on a foundation: one room for living and sleeping with a kitchenette, bathroom with shower, closet. No porch, deck or patio.” An AI architect drafted the room program, a layout solver placed every wall and door, and the plan was checked automatically for room sizes, circulation and daylight. The same project produced the PDF sheets, layered DXF, IFC model and 3D model you can download above.
