The walls around the stairwell are also angled in deference to the curve, making it necessary for each stair to have a slightly different shape and size from the last. That's where the expert local glass artists at Meltdown Glass came in. "We had a tight budget on the stairwell, but we spent the money where we needed to, on the glass risers," says Tate. Each tread was handcrafted by a glass artist and kiln fired. An engineer was brought in to make sure the stairs were structurally sound, were safe and met codes such as slip-resistance requirements. The stairwell also provides passive solar heating during the winter months, picking up warmth and circulating it. "The sun bathes the staircase
in sunlight during certain times of day, transforming it into a crystal staircase," he says. The home is Scottsdale Green Build certified.
