This house is a re-interpretation of a Case Study era house that existed on the site. We worked from the original site plan, with the house perched on a rock retaining wall, within the fractured limestone cliffs of the Balcones fault or eschelon. The house is two-faced; one side looks downhill into treetops, and one looks uphill into a rock garden tucked between house and hill. Similarly, rooms lined in pine have warm southern light and contrast rooms with skim-coat plaster with cooler, northern light. In the large family room, both come together with a clerestory window at the joint.
