Experience Boulder's most coveted lifestyle in this exceptional residence, just steps from Chautauqua Park and Auditorium. Set on a generous half-acre lot with over 7,200 square feet, the home combines timeless design with modern updates, recently completed by Donohoe Builders, and interiors by Deidre Oliver of Oliver Designs. The main level welcomes with a marble foyer leading to an open, light-filled floor plan. At its heart, a chef's kitchen features a striking white quartz waterfall island, Sub-Zero refrigeration, six-burner Wolf range, two Bosch dishwashers, and a built-in coffee-espresso maker. Adjacent spaces include a sitting room with sliding doors to the backyard, a stylish office with moss rock fireplace, a 5-person spa room with hot tub and outdoor shower, and a living and dining area with vaulted ceilings and wall-to-wall windows framing breathtaking Flatiron views. Upstairs, the primary suite offers a private deck, wood-burning fireplace, and luxurious bath with soaking tub, Carrera marble shower, dual walk-in closets, and laundry. A guest bedroom with adjacent full bath is ideal as a nursery, office, or overnight guest stay. The lower levels provide three additional bedrooms with walk-in closets, two shared full baths, a dedicated office with deck, media room, gym/recreation space, and flexible living areas with backyard access. Outdoors boasts, mature landscaping, a flagstone patio and multiple private decks. Thoughtful interior details like custom lighting, skylights, walnut and white marble flooring, plantation shutters, and Pella windows create an inviting, modern environment. With hiking trails, concerts, and community events just steps away, plus Pearl Street's dining and shopping a minutes drive from home, this property offers a rare combination of sophistication, comfort, and connection to Boulder's iconic natural and cultural lifestyle.
