Texas architect Jim Poteet helped Stacey Hill, who lives in a San Antonio artists’ community, wrangle an empty steel shipping container into a playhouse, a garden retreat and a guesthouse for visiting artists. The container measures a narrow and long 8 by 40 feet; Hill asked that a portion of the square footage be retained as a garden shed and the rest serve as the living space. The architect added floor-to-ceiling glass doors and windows, heating and air-conditioning, a green roof, bamboo flooring and wall covering, a small sink and shower and a composting toilet, and placed the structure on a base made from recycled telephone poles.
