1721 Peninsula Circle

There are homes that impress, and homes that restore. This is the latter, where light moves gently through open spaces and the landscape becomes part of daily life. Backing to Plum Creek Golf Course, with mountain views and unforgettable sunsets, the setting feels expansive yet deeply calming. The kitchen is refined and welcoming, anchored by a statement island and custom lighting that elevates everyday rituals. From here, the home opens naturally into the family room and out onto the deck, where golf course greens and mountain horizons create a beautiful backdrop for gatherings large and small. The primary suite offers a true retreat, featuring a generous sitting area, fireplace, and a well appointed bathroom with a spacious tub, walk in shower, and views that bring a sense of calm to the start and end of each day. Upstairs, additional bedrooms are thoughtfully arranged. Two share a Jack and Jill bath, while another enjoys its own ensuite, offering comfort and privacy for family or guests. The fully finished walkout lower level mirrors the quality of the main home, with tall ceilings, living space, bedroom, laundry, private patio, and a beautifully finished full kitchen with thick quartz counters and ample cabinetry. The lower level bathroom is equally impressive, featuring a Japanese soaking tub integrated into a glass enclosed shower with a full body shower system, creating a space that feels both intentional and restorative. Ideal for multigenerational living or extended stays. A former model home, thoughtfully updated throughout with custom designer lighting in every room, a full stucco exterior, and a concrete tile roof that speaks to enduring craftsmanship and long term value. The walkout lower level lives like a private residence, fully equipped for comfort and flexibility. A home designed for balance, flexibility, and longevity. Step into a lifestyle that feels both elevated and grounding. Schedule your private showing and experience it in person.
