The gourmet kitchen is a showstopper, featuring a massive quartz island with seating for 4-6, extensive cabinetry and counter space, upgraded stainless appliances, 5-burner gas cooktop, soft-close cabinets, designer pendant lighting, and spacious walk-in pantry. LVT flooring and Hunter Douglas window coverings add style and quality throughout the home.

The inviting living/dining area features vaulted ceilings, upgraded LVT flooring, and a dramatic modern gas fireplace wall. Sliding glass doors open to a covered, lighted patio overlooking the open space—an ideal setting for morning coffee, relaxing evenings, or entertaining.

The private primary suite offers high ceilings, open-space views, ceiling fan, upgraded carpet, a beautifully finished 5-piece bath, and large walk-in closet.

Enjoy Colorado outdoor living without the maintenance. The fully fenced yard features premium artificial turf, a flat play area, professionally designed drought-tolerant landscaping, and auto-drip irrigation.

The finished basement adds tremendous versatility with a large second living/entertainment area, wet bar/2nd kitchen, bedroom, bathroom with walk-in shower, abundant storage, and room to add another bedroom.

Additional highlights include a 3-car garage, mud room, upgraded lighting, plumbing, & flooring throughout, and more.
