An unparalleled opportunity awaits! This expansive flat, graded, park-like, fully-fenced lot, encompassing approximately 9,517 square feet, per the Los Angeles County Assessor's Office, presents a rare chance to design a custom estate or explore development possibilities on one of Altadena's most sought-after streets. Situated in the Country Club neighborhood, this location offers a tranquil private setting with unlimited potential. The former house, built in 1930, was a 3,080 square foot, five bedroom, three bath Mediterranean, plus a fully permitted 362 square foot ADU, that boasted beautiful views of the majestic San Gabriel mountains rising in the distance. The parcel is an idyllic blank canvas for creating a once-in-a-lifetime masterpiece, on a very desirable site that comes with plans done by esteemed architect David Law, as well as lot surveys, geotechnical studies, site plans, arborist reviews, a cleared regional plan application, as well as a root study. This lot is ready to go and the opportunities abound! Both Phase I and Phase II of the environmental cleanup and debris removal have been completed, further enhancing its readiness for redevelopment. The property also has water and electricity. All buyers will benefit as initial building protocols have been streamlined to expedite the review process, whether you use the previous renderings, or create your own dream home and construct a larger structure. This is a must see!
