Frank Lloyd Wright in Iowa
If you live in east central Iowa, treat yourself to a visit to Cedar Rock, one of FLW's Usonian houses. It was built for an Iowa businessman; once he and his wife passed away, they left their beloved house to the Iowa Department of Natural Resources, including a trust to take care of the house in perpetuity. So it's free to visit.
My brother, also a fan of FLW, visited from Los Angeles where he has gone through FLW houses such as Hollyhock. He's been to Taliesen. After seeing Cedar Rock, he said it's his favorite Wright house, period. It's small and intimate and only so many people at a time are there with you. For a short while you can almost imagine yourself living in this beautiful house on a beautiful bend in the Wapsipinicon River just outside of Quasqueton.
This is one of the houses that Wright deigned to "sign," shown by the red glazed tile with his initials that is near the entryway to the house. Notice also how the grout between the bricks is visible in the horizontal plane, but that the vertical grout has been darkened. Wright did this to emphasize the horizontal appearance of the long, low house, anchoring it to the landscape.
