A rare opportunity in the heart of Lafayettes highly desirable Happy Valley! Privately tucked away along a private road shared by only three residences, this special property offers beautiful views across Happy Valley, mature trees and a relatively level building area ready for your vision. Previously developed lot with a new driveway, water and electricity already in place. Plans for an approx. 3,831 SF two-story residence with 2-car garage were previously approved by the City of Lafayette and a building permit was obtained. While approvals have expired, the existing plans, engineering and extensive groundwork may provide a significant head start. Architect and builder familiar with the project may also be available to assist. Build an incredible custom residence and explore the potential for an ADU, pool, gardens, pickleball/tennis court and exceptional indoor-outdoor living. An exciting opportunity for homeowners, builders or investors in an area where newly built luxury homes have sold above $4M. Easy access to Hwy 24 and San Francisco. Seller financing may be available.
