About this House

Motivated Seller! A new standard of luxury awaits in Newlands. Designed by the visionaries at Mosaic Architects, this stunning residence is where bold design meets effortless elegance and QUALITY construction. Set on a sprawling 9,000+ SF lot, every detail of this home is intentional. The WOW factor begins the moment you head inside! The dramatic two story foyer with its striking stair hall welcomes you and entices you through the open concept living areas where THREE sets of Marvin collapsible doors open to create a seamless integration of indoor an outdoor living. White oak floors anchor the spaces while custom cabinetry, a huge pantry, a timeless palette, and top of the line appliances provide the backdrop for culinary creations as well as quick weeknight suppers. The outdoor veranda offers tons of shade in summer months to relax and read a book as well as multiple eating and conversation areas for creating memories and laughter well into the evening. The open-concept layout adapts to your lifestyle, offering comfort, flow, and refined functionality at every turn. You'll be hard pressed to find a home with more soft filtered light throughout. The Owner's Retreat with soaring ceilings and a huge patio, steam shower, and custom cabinetry with under lit vanities provide the perfect sanctuary to unwind every evening and awaken each morning. Two additional en suite bedrooms and a bonus flex room complete the upper level. Even the lower level seamlessly integrates into the home with open stair hall, high ceilings, and a large feature media wall with 81" television and under cabinet lighting. A 4th bedroom and optional 5th bedroom flex exercise room completes your experience that leaves you feeling inspired and at peace. Why settle for a dated remodel or wait 3 years to build new when you can have it all now! Brand new, intelligently crafted, and move-in ready? This is your Nirvana in Newlands. LIVE BOLDER, LOVE BOULDER!
