About This Home
As of July 2026An architectural masterpiece with historical significance located in Mason City's Rock Glen district. Designed by renowned architects, Walter Burley Griffin & Marion Mahony Griffin, this home pays homage to the Prairie School style with carefully planned sightlines, natural light & materials, open floor plans & harmony with the landscape. Situated in a park-like setting along the banks of Willow Creek, you will enjoy exquisite views of the Glen & melodic sounds from the Parker's Mill waterfall. Built below street level, a few highlights of the home include original hardwood floors, signature Grueby tile fireplace, distinctive bedroom "tent" ceilings, luxurious primary bedroom on-suite, terraced garden landscape & an amazing, oversized patio. Owners have spent the last decade renovating most rooms with distinct attention to detail & the goal of blending historical charm with modern living. The Griffins would approve! Here's your chance to become a part of this historic home's legacy!
