After the design was developed and permits were in hand, our team excavated the hillside so that the footings and foundation could be poured. The stucco exterior was matched to that of the existing home, while Bluestone Flagstone pavers were found to blend the new patio into a seamless extension of the existing one. The couple selected a NanaWall door system so the doors could be opened completely in nice weather, providing an unobstructed flow to the rest of the patio. Gable windows and skylights provide optimal light while the couple and their guests stay warm and dry regardless of the weather. Comfort is managed year-round with a fireplace, while additional Infratech heaters are mounted over the NanaWall doors for use on particularly frigid days. Warm days are cooled with a gentle breeze from their Haiku ceiling fan.
