Home Details

Open House on Sunday (9/14), 1-2 PM! Behind a dramatic illuminated gate on a lush 0.57-acre lot, this architecturally refined residence was remodeled by renowned architect Harvey Hine and embodies the pinnacle of modern luxury and design. A striking wood exterior, standing seam metal roof, and grand slate patio set the tone for the sophisticated living experience within. Enter through an oversized pivoting wood door into a sun-drenched great room with soaring vaulted ceilings, a statement fireplace, and warm maple hardwood flooring. Walls of glass frame the open-concept living space, seamlessly connecting to an expansive rear deck-an entertainer's dream. The chef's kitchen features custom cabinetry, waterfall stone island, tile backsplash, walk-in pantry, a Wolf range, and a Sub-Zero refrigerator-offering both form and function in equal measure. A cozy library lounge leads to a versatile home office or fifth bedroom with direct access to the front patio. The main-level primary suite is a private retreat with a generous walk-in closet and a spa-inspired en suite bathroom. On the lower level, a fully finished space includes a media room, fitness area, and guest suite-perfect for everyday living or hosting visitors. The beautifully landscaped grounds are surrounded by 40-50' evergreens and enhanced by natural boulders, stone patios, a seasonal ditch, water feature, and multiple serene seating areas. A bonus heated studio offers flexible use as a gym, art studio, or private office. Additional highlights include an attached two-car garage, ample guest parking, and a show stopping gated driveway. Located in the coveted Newlands neighborhood with close proximity to North Boulder shops, downtown, open space, hiking trails, and top-rated schools, this extraordinary home offers the ultimate blend of luxury, privacy, and convenience. Be sure to view the virtual tour and listing video-this one is not to be missed.
