Builder cements plans for homes

Builder cements plans for homes: "Dave Keller is building what is apparently the Valley's first subdivision of concrete homes in decades. The concrete increases energy efficiency and makes the homes quieter and resistant to termites, mold and fire. The subdivision, Sunset Trails IV at 40th Avenue and Lone Cactus Drive in northwest Phoenix, will contain 34 homes of 3,000 to 4,000 square feet, including full finished basements and inside and outside concrete walls, selling for $115 to $120 a square foot. 'That's comparable with 2-by-6 (wood frame) construction prices,' Keller said. 'This is the only development in the Valley to my knowledge where the entire subdivision is all concrete homes.' Decades ago, houses in the Maryvale neighborhood were built of concrete blocks, and some newer custom homes have been built with concrete walls. But Keller said his will be the first all-concrete subdivision."
