Inside, you are welcomed by a spacious living room featuring tray ceilings, expansive windows framing serene mountain and pastoral views, and in-floor electrical outlets for added convenience. The open-concept layout—highlighted by bamboo flooring throughout with no carpet anywhere—flows seamlessly into a show-stopping kitchen with floor-to-ceiling white shaker cabinetry, stainless steel appliances, under-cabinet lighting, a stainless farmhouse sink, granite countertops, and an inviting dining area filled with natural light. A walk-in pantry and dedicated home office add both convenience and versatility.
