Property Description

Downtown Boulder base camp, the backdoor of Mt. Sanitas Trailhead and the heart of Boulder's Porchfest, Mapleton Garden Tour and all Sundance festivities.

Gracefully positioned on an expansive 10, 542 sq. ft. corner lot, the property is enveloped by lush, mature landscaping, privacy and tranquility all while feeling connected the vibrance of this special block. A classic wraparound porch captures sweeping Flatirons views, while curated outdoor spaces - including a serene backyard yoga deck - offer an effortless balance of relaxation and refined entertaining. Inside, a welcoming foyer and elegant formal parlor set the tone, flowing seamlessly into gracious living and dining spaces designed for both intimate gatherings and grand occasions. The gourmet kitchen serves as the heart of the home, appointed with Italian marble, rich cherry hardwood cabinetry, a JennAir gas range, and a bespoke walnut breakfast table- where craftsmanship and functionality meet in perfect harmony.

A secondary bath offers a spa-inspired escape, complete with an aromatherapy steam room and a timeless clawfoot soaking tub. Thoughtfully refreshed with new designer lighting, upgraded appliances, and refined kitchen and bathroom finishes. The front patio showcases beautifully refinished flooring, behind the home a new garage roof and door and meticulous exterior touch-ups. Ideally situated on one of Boulder's most coveted streets, welcome to the Casaday-Winter House. An irreplaceable piece of Boulder's heritage, where historic character and modern sophistication converge. For your convenience, all furnishings available.
