Perched on 10 treed acres in the desirable horse-friendly community of La Tierra Nueva, this architecturally designed passive-solar contemporary home has extraordinary views of four mountain ranges and the lights of Los Alamos. A series of interconnected wings and levels, it hugs the contour of the land to maximize views, while the passive solar design takes advantage of the site, climate, and materials. Highlights include an entry solarium and gallery, a chef's kitchen, a dining room with a fireplace, a generously proportioned great room with a fireplace, a grand master suite with an exercise and reading room, a guest bedroom, an office, a private studio or second guest bedroom, and a workshop with a cedar closet. The front courtyard features rock walls, a flagstone walkway, a tranquil water feature, and beautiful landscaping. The large back portal is ideal for outdoor entertaining or intimate alfresco dining. Downtown Santa Fe and the local airport are less than 30 minutes away.
