Property Overview and Key Details
The One is a mega-mansion in Bel Air, Los Angeles, developed by Nile Niami. The property spans approximately 105,000 square feet and sits on a 3.8-acre lot with panoramic views of the Los Angeles basin and the Pacific Ocean. It includes a 5,000-square-foot master suite, a 30-seat theater, a 5,000-bottle wine cave, a 500-foot infinity pool, and a helipad. The listing has been priced at $295 million, making it one of the most expensive residential listings in the United States. The project was originally conceived as a showcase for ultra-luxury residential design and engineering.
The property features 21 bedrooms, 42 bathrooms, a two-story library, a fitness center, a spa, and a two-story car gallery capable of housing over 20 vehicles. The home includes smart-home automation systems, a custom-built security infrastructure, and extensive outdoor landscaping by renowned designers. Construction began in 2014, and the project faced multiple delays due to regulatory reviews, engineering challenges, and market conditions. The main residence is complemented by separate guest quarters, a gatehouse, and extensive sports and entertainment facilities.
Ownership, Sales History, and Market Context
The One was originally listed for $500 million in 2017, later reduced to $340 million, and most recently listed at $295 million. The property has been listed with multiple luxury real estate firms, including Hilton & Hyland and Compass, and has been marketed to international buyers. Nile Niami, the developer, has publicly discussed the challenges of selling a property at this price point, noting the limited pool of qualified buyers. The listing price reflects adjustments for market conditions, construction costs, and the current ultra-luxury real estate environment.
The sale of The One is subject to ongoing negotiations and has been covered by major outlets including Forbes and The Wall Street Journal. The property is located within the Bel Air neighborhood, which remains one of the most prestigious residential areas in Los Angeles. Comparable sales in the area include other high-profile estates, though none have matched the scale and price of The One. The transaction, if completed, would set a new benchmark for residential real estate in the United States.
Design, Construction, and Regulatory Context
The design of The One was led by architect Paul McClean of OMA, with engineering and construction management handled by multiple specialized firms. The project required extensive permits and approvals from the City of Los Angeles, including variances for height, lot coverage, and environmental impact. Construction faced scrutiny from local residents and regulators over issues including traffic, noise, and visual impact. The project also required custom engineering solutions for its massive scale, including structural reinforcement, advanced HVAC systems, and bespoke interior finishes.
The One has been featured in architectural and real estate publications, and its construction process has been documented in media coverage. The property includes sustainable design elements such as energy-efficient systems and water management features, though its overall environmental footprint has been a subject of public discussion. The development reflects broader trends in ultra-luxury residential construction, where bespoke design, advanced technology, and exclusivity drive both cost and market positioning.
