AUCTION: Bidder registration deadline: 4 November. Starting bids expected between $3M-$4M. Set just below the iconic Flatirons in the storied Chautauqua neighborhood, this 2008 residence by celebrated Boulder architect Harvey Hine, remodeled throughout in 2023, unites a restored 1914 stone cottage with a striking nautilus-shaped contemporary addition. A soaring 23-foot entry with a dramatic cantilevered staircase introduces an expansive open layout where historic character and modern design converge, finished with the finest custom details throughout. Gently curved walls, vaulted ceilings, and a kitchen that opens to a private deck create seamless indoor-outdoor flow, while a main-level primary suite offers two walk-in closets and a private office. Thoughtful landscaping ensures privacy, yet Chautauqua Park trails are just two blocks away and downtown Boulder dining is only minutes from the door.
