2026 RDAA | Architectural Interiors | Tierra de Paz | Cotton Estes Architect

Tierra de Paz playfully flips the courtyard concept of the nearby historic Spanish colonial missions. Four flat-roofed bedroom and office volumes rotate around a soaring, skylit main living area, each of them separated by patios facing the four cardinal directions. The resulting light from all sides, along with earthy yet austere materials, gives this living space the sense of an open-air pavilion. Its western red cedar ceiling rests lightly on plastered walls, recalling the mission outposts’ masonry walls and lightweight roofs.

“One of the most rewarding aspects was the skill of craftsmen we were able to engage on the plaster work, custom light fixtures, carpentry and ceiling, and floor,” says Cotton Estes, AIA. “We experimented with casting larger aggregate pieces of limestone and exposing them in the slab finish. It brings a lot of nuance and life to otherwise simple planar forms.”

Our judges praised the “inventive plan, which was very well presented; they brought us along with their drawings and diagrams.” The panel also applauded its “uber-crisp, minimalist detailing. It is completely recognizable as vernacular and completely minimalist with its knife-edge materials,” a judge said. “A lot of people could be comfortable in this sort of domestic environment, even though it’s pushing a lot.”
