Set on a desirable .26-acre corner lot within the North Tustin foothills, 13132 Barrett Hill presents a refined single-level Mid-Century Modern residence on a cul-de-sac setting. The home offers three bedrooms and two-and-one-half bathrooms with an open, flowing layout designed to support both everyday living and entertaining. Warm architectural character, a cozy fireplace, and multiple access points to the backyard create a seamless connection between the interior spaces and the outdoor grounds. The private backyard serves as a standout feature, anchored by a custom designer swimming pool by Pesner Pools and dramatically framed by imported natural granite boulders sourced from an Arizona quarry. The lagoon-style pool is complemented by a spa with a cascading waterfall, creating a tranquil resort-inspired environment for outdoor dining, entertaining, and relaxation. Additional highlights include backyard access from the primary bedroom and kitchen eating area, along with an indoor laundry area and adjacent three-quarter bathroom offering convenient use from the pool area. Located near Arroyo Elementary, Hewes Middle School, and Foothill High School, the property also offers convenient proximity to shopping, dining, and major commuter routes. With its single-level design, distinctive Mid-Century Modern character, and exceptional outdoor setting, this North Tustin residence presents a compelling opportunity in a well-established foothill community.
