The journey to Topanga's Iconic Powderhorn Ranch begins traveling through the ancient tree tunnels of coastal oaks lining the private road leading to the bucolic 5 acre sanctuary surrounded only by distant views and 1000's of acres of bordering parkland. The stunning main house by Kanner Architects (2011) is surrounded with sliding glass walls under the open beamed ceilings that open to scenery in all directions. A gourmet kitchen, deluxe master suite, and guest bedrooms are all finished with exquisite detail, materials, & craftsmanship. All main areas are bathed in natural light and lead out to massive decks, huge grassy lawns, and the pool area with fire pit and exotic wood sundecks. Venture further onto the grounds beyond a horse arena to the detached casita with wood burning stove and office waiting to serve as a studio for art, music, or your practice. Return to the main house passing private terraces that overlook the Backbone Trail, rock formations, wheat fields, and grasslands.
*Taxable value of land and structures on it ("additions") is determined regularly by local assessors and does not affect market price.
