The roof had all but succumbed to water damage. Animals had burrowed indoors, interior fixtures were missing or crumbling away and the heating and plumbing systems were shot. The Seth Peterson Cottage was unlivable.
In 1989, volunteers set about restoring the last building commissioned in Wisconsin from the world-famous, Wisconsin-born architect Frank Lloyd Wright. The renovation lasted until 1992, when the Seth Peterson Cottage became an overnight destination for countless travelers who would stay there and experience, firsthand, the magic of living in a Wright-designed building.
