Ready-to-issue plans for a beautifully designed 2,183 square foot single-story residence with a 488 square foot garage add exceptional value to this prime Altadena homesite. Situated in one of Altadena's most desirable neighborhoods, this lot sits on a quiet street surrounded by intact neighboring homes. Located in the heart of Altadena, 1137 E Mariposa provides convenient access to the community's most treasured landmarks, including the Altadena Country Club, Altadena Golf Course, Altadena Library, Christmas Tree Lane, and Mariposa Village. It's also just moments from popular hiking trails and all that neighbor Pasadena has to offer. The backyard features original hardscape elements, including a decorative tile pool, separate in-ground spa, spacious patio, and basketball court. The garden that surrounds the pool includes a mature palm and plumeria tree. Set at the end of a shared driveway, the lot offers a private and peaceful atmosphere with a strong sense of seclusion. Public records indicate the previous residence featured four bedrooms, three bathrooms, and 2,410 square feet of living space. Phase 2 debris removal has been completed, and the property is being sold as land only.
