Plan drawn to the render. Room dimensions on the drawing; areas sum to the stated floor area. A construction set follows the House No. 1 pipeline.

Two identical 980 square foot units share one hillside lot, each banking its bedrooms uphill so the living end can stand on stilts and open wide to the view.
