The overarching goal is to convey a modern ruin—clean, elegant form with a weathered, hand-hewn feel. As the building site is at the boundary of Agua Fria village on the Camino Real de la Tierra Adentro, we merged a modernist sensibility with a materiality drawn from this once-rural community. The rusting steel panels and exposed rammed-earth sit gracefully in the company of vernacular chicken houses, garden sheds and old barns. The structure has an unmistakable sense of mass and solidity while still encouraging interplay between indoor and outdoor environments. The architect and owner worked collaboratively to conceptualize the design and plan its execution. It was critical to create a plan that allowed the owner/builder to perform as much of the labor and finishing as possible. Additional factors informing the design include a rooftop deck reached via the single upstairs bedroom, with space for a future green roof. Water catchment and gray water reuse are key to maintaining cottonwood and aspen trees, limber pines, native grasses and restoring the property's historic orchard.
