An exceptional opportunity to create a custom luxury residence in the scenic hills of Walnut. Tucked away at the end of a quiet cul-de-sac, this approximately 15,575 SF hillside lot offers privacy, tranquility, breathtaking hillside views, and sparkling city lights.Adding to its appeal, the property benefits from substantial pre-development work already completed. Previously approved subdivision and architectural plans for an approximately 3,900 SF custom home may provide significant time and cost savings for the future owner, builder, or investor. Additional value includes grading-related engineering work, compaction reports, and an existing 6-inch sewer line reportedly installed within the property, potentially reducing future infrastructure costs and development timelines. Surrounded by established luxury residences, this rare homesite presents an outstanding opportunity to build a dream estate, develop a custom project, or secure a long-term investment in one of Walnut’s desirable hillside communities. Conveniently located near top-rated schools, parks, shopping, dining, and major transportation corridors, the property combines natural beauty, privacy, and everyday convenience. Opportunities like this are increasingly rare—a premium hillside lot with views, utility improvements, prior approvals, and exceptional potential to bring a vision to life.
