Located on one of the few lots in Dallas elevated enough to enjoy a view of the downtown skyline, the Vertical House rises dramatically above the tree tops to capture views of the city. The compact footprint accentuates the vertical experience of the home and is carved into the limestone strata, centered in a spiraling entry drive that creates a subterranean approach to the home. As the homeowner moves vertically through the home, every space is immediately accessible from the glass-enclosed stairwell. The stair and every level enjoy butt-glazed windows looking to the northeast and downtown. Sixty- foot-tall tubes protect the glazing on its western exposure, serving both as the home’s primary structural support and leading visually upward before turning 90 degrees to shield the rooftop deck atop the home. The rear façade is clad in locally-quarried roughback Leuders limestone, providing solar and privacy protection from adjacent neighbors to the south. A pool house located on the north side of the property contains a gym and guest accommodations alongside a 65-foot lap pool. A tubular steel trellis echoes the design of the main house, in this case taking the form of a long, low-slung canopy.
