Though it would make for an ideal tiny home, this Container Guest House in a San Antonio, Texas backyard functions as the perfect accommodation for visitors. As is the norm with container homes, environmentally friendly practices were top-of-mind, explaining why Poteet Architects kept its original blue color, along with the exterior text. There are plenty of other green features as well. The addition of a floor-to-ceiling window adds natural light, while sliding doors provide plenty of fresh air. The roof garden is watered by grey water (runoff water from the sink and shower). The bathroom contains a composting toilet, and recycled soda bottles are part of the deck’s building materials. If that’s not enough, the exterior light fixtures are local tractor blades, and the foundation consists of — you’d never guess — recycled telephone poles.
