Outdoor, Back Yard, Shrubs, Small Pools, Tubs, Shower, and Small Patio, Porch, Deck The back of the home glows at night as the giant, two-story glass doors swing open to remove the barrier between inside and out. A polished concrete patio deck and pool, along with a simple block perimeter wall, make smart use of available materials. The pool acts as a passive conditioning tool, cooling air before it enters the house. The block wall is positioned 31 inches from the house, creating a gap or "air chimney" that allows air to circulate up and away from the home, while simultaneously letting light filter down.
