About This Property

Coveted Newlands living meets the soul of mid-century modern design in this light-filled Boulder residence. A sophisticated dark slate exterior commands attention with understated, architectural curb appeal; a striking counterpoint to the home's sun-drenched, open interiors. Soaring pitched ceilings define the generous living and dining area, where a clean-lined fireplace serves as a natural gathering point and sculptural focal point. The adjacent kitchen is both functional and refined, featuring stainless steel appliances, a classic tile backsplash, and an expanse of streamlined cabinetry that honors the era's commitment to purposeful design.Sliding glass doors, a hallmark of mid-century indoor-outdoor living, open to a private balcony framed by sweeping city views, blurring the line between interior comfort and the Colorado landscape beyond. Each bedroom is a warm, light-filled retreat, flexible enough to serve as a thoughtfully appointed home office, a welcoming guest room, or a quiet personal sanctuary. The lower level continues the home's luminous character with a spacious recreation room and walkout access to the backyard; seamlessly connecting interior and exterior living in true mid-mod fashion.The terraced outdoor space unfolds across multiple levels, grounded by mature trees and native landscaping that feel both organic and intentional. Whether cultivated as a garden retreat or left to breathe as a naturalistic backdrop, the setting is as considered as the architecture itself. With effortless proximity to Boulder's nature trails, Mount Sanitas, North Boulder Park, and the city's celebrated amenities, this is Colorado living at its most elemental and elegant.
