About This Property

Open House has been cancelled, we are under contract with a backup contract in place. No more showings. A true jewel box, lovingly maintained and thoughtfully updated, set amid one of the most extraordinary gardens you will find in Boulder. Inspired by years the owner and her family spent living in England, and by the gardening traditions she learned from her mother there, the lush English-style gardens have been lovingly cultivated over many years.

Meandering plantings, mature vegetation and intimate outdoor spaces create a setting that feels private, established and truly special. Inside, the home is equally inviting, with abundant natural light, beautifully refinished hardwood floors throughout the main and upper levels, and Pella windows framing the beautiful surroundings. A bay window fills the living room with light while providing another wonderful vantage point for enjoying the gardens. The kitchen features maple cabinetry, slab granite countertops, stainless steel appliances and recessed lighting, and opens through a Pella sliding glass door to a large covered patio overlooking the gardens, creating a wonderful connection between indoor and outdoor living.

The main-floor dining room, with its fireplace and brick and flagstone hearth, offers wonderful flexibility and could be converted to a cozy main-floor primary suite with the addition of a door. Upstairs, the light-filled primary bedroom and second bedroom are tucked beneath charming dormers, with window seats and reading nooks that add warmth and character. Seasonal Flatirons views provide another distinctly Boulder touch. The finished basement expands the living space with a large family room, updated full bath, nicely appointed laundry room and two additional bedrooms, one conforming and one non-conforming.

Charming, intimate and beautifully cared for, this is a home where thoughtful updates, wonderful character and extraordinary gardens come together in a way that is increasingly difficult to find.
