Coolidge Haven is a custom-built contemporary residence designed around luxury, wellness, and modern Los Angeles living. The expansive four-bedroom main home is complemented by a private one-bedroom ADU with its own entrance and outdoor space, creating exceptional flexibility for guests, extended family, a home office, or rental income. The main residence features bright, open living spaces, refined custom finishes, a designer kitchen, and a finished basement with 10-foot ceilings, a wet bar, game room, full bathroom, and impressive 150-inch home theater. The home is offered fully furnished, providing a truly turnkey opportunity. Built as a Healthy Home, Coolidge incorporates systems and materials rarely found in conventional residential construction. Two energy recovery ventilation systems continuously introduce filtered fresh outdoor air while exhausting stale indoor air. Five-zone heat pump HVAC, MERV-13 filtration, high-performance insulation, and an airtight building envelope provide consistent comfort and efficiency throughout the home. Low and no-VOC materials, Greenguard-certified adhesives, all-electric systems, and Schluter waterproofing in every bathroom further support a healthier, more durable indoor environment. Additional construction highlights include Windsor casement windows, premium flooring and cabinetry, a standing-seam metal roof, and thoughtfully designed drought-tolerant landscaping. Currently operated as a professionally managed furnished rental with an established operating history and strong guest reviews, the property offers several possibilities: occupy it as a primary residence, use it as a second home, accommodate multigenerational living, or continue operating it as a furnished rental. Coolidge Haven is a rare opportunity to acquire a fully furnished custom residence combining thoughtful architecture, advanced building performance, exceptional indoor air quality, and valuable income-producing flexibility.
