Tucked at the end of a quiet cul-de-sac in the prestigious hills of North Tustin, this exceptional 14,975 sq. ft. homesite represents one of the most desirable parcels within the Lemon Hill Luxury Estates enclave. Originally held back by the developer as the premier lot of the six-lot offering, the property enjoys a private setting, expansive views over Lemon Heights and Tustin Ranch, and a mostly flat buildable footprint rarely found in hillside communities. The property comes with two completed sets of architectural plans, offering buyers the opportunity to move forward with a stunning custom home without starting the design process from scratch. The plans include either a beautifully designed 6,517 sq. ft. two-story single-family residence or a 5,771 sq. ft. two-story single-family residence, both thoughtfully designed with a pool and a rooftop deck to maximize the surrounding views and indoor-outdoor Southern California lifestyle. The generous dimensions and gentle topography provide an ideal canvas for designing a custom residence with seamless indoor-outdoor living, expansive view terraces, and resort-style amenities. From a future two-story home, the property offers the potential for distant ocean views, adding yet another layer to an already exceptional setting. Surrounded by established homes in a peaceful and well-regarded neighborhood, the lot combines privacy with convenience. Residents enjoy easy access to premier shopping and dining at Irvine Spectrum, South Coast Plaza, and Enderle Center, along with the historic charm of Old Town Orange. Outdoor recreation is just minutes away at Peters Canyon Regional Park, known for its scenic hiking, biking, and walking trails. Located within the highly acclaimed Foothill High School district and offering convenient access to the 55 and 5 freeways along with the 241 and 261 toll roads, this rare homesite presents a unique opportunity to create a custom residence in one of North Tustin’s most sought-after hillside communities.
