    What's special

    Fully daylight lower levelFloating staircasesLuxurious ensuite bedrooms
    THE OBSERVATORY has arrived.Bel Air's next great modern estate is ready to be completed. Set behind gates in one of Los Angeles' most coveted enclaves, this extraordinary nearly completed architectural masterpiece spans approximately 9,200 square feet and captures sweeping panoramic views from Downtown Los Angeles to the Pacific Ocean. Offered approximately 85% complete and sold in its current unfinished condition, THE OBSERVATORY presents a rare opportunity to finish a future trophy estate in prime Bel Air. The following reflects the residence as envisioned upon full completion: Designed with striking scale and dramatic architectural presence, the residence is envisioned with soaring 12-foot ceilings, floating staircases, and walls of Fleetwood glass framing endless city-to-ocean vistas. Expansive covered terraces throughout create seamless indoor-outdoor living and entertaining on every level. Planned resort-style grounds include a spectacular pool and spa with floating pavers, an oversized step-in lounging platform, built-in barbecue area, and multiple outdoor entertaining spaces anchored by dramatic Da Vinci fireplaces. The home is also designed with both a show kitchen and separate chef's kitchen, blending elevated design with effortless functionality. The fully daylight lower level is planned to feature an entertainment lounge, bar, wine cellar, theater, gym, steam shower, dry sauna, guest suites, and expansive outdoor patios. Upstairs, luxurious ensuite bedrooms culminate in an exceptional primary retreat complete with fireplace, private terrace, spa-inspired bath, and oversized dual closets. Crowning the residence is an approximately 2,730 square-foot rooftop deck with multiple lounge areas and breathtaking panoramic views stretching across the Los Angeles skyline to the ocean. Additional planned features include elevator access to all levels, smart home automation, and exceptional designer finishes throughout. A rare and compelling opportunity for a developer, investor, or visionary end user to complete one of Bel Air's next iconic modern estates.
