Overview
Welcome to effortless main-level living in Montaine’s sought-after Regency Collection, Castle Rock’s premier 55+ luxury community. Ideally located on a quiet cul-de-sac, this 2022 Toll Brothers ranch offers refined design, low-maintenance living, and an active lifestyle just minutes from downtown Castle Rock. The open-concept floor plan is filled with natural light and features high ceilings, wide plank flooring, and a stunning great room with front range views, gas fireplace and large nesting sliding glass doors, creating a seamless indoor-outdoor flow perfect for entertaining. Electronic window coverings throughout the home add modern convenience and a polished finish. The gourmet kitchen is the heart of the home, showcasing an oversized island, custom cabinetry, quartz and granite countertops, double ovens, walk-in pantry, and generous prep space—ideal for both everyday living and hosting. The primary suite is a private retreat, complete with its own gas fireplace, radiant heated floors in the spa-inspired five-piece bath, and a spacious walk-in closet. A secondary bedroom with ensuite bath and a dedicated home office provide flexibility for guests, hobbies, or work-from-home needs. Convenient main-level laundry enhances ease of living. Step outside to the covered composite deck and enjoy open views and peaceful surroundings. The south-facing driveway naturally melts snow, a thoughtful Colorado convenience. Additional highlights include owned solar panels, central A/C, an oversized 3-car garage with EV hookup, and a level, professionally landscaped lot. The walk-out basement is unfinished and ready for future expansion. Montaine offers a true resort lifestyle with pickleball, tennis, bocce, lap and lounge pool, spa, clubhouse, fitness center, and over 13 miles of trails across 548 acres of open space. Snow removal and trash are included. This is downsizing done right—luxury, comfort, and community in one exceptional home.
