We've visited several Frank Lloyd Wright homes ranging from Falling Water (Pennsylvania) and Darwin Martin and Graycliff (Buffalo) to Taliesen West (Scottsdale) to Usonian homes in northern Ohio. If you have any interest or curiosity in Frank Lloyd Wright or architecture, you definitely want to come here and to give yourself some additional time to see other nearby FLW structures.
This is Frank Lloyd Wright's family home, which he designed and expanded. It was fun to see how he himself lived and to hear stories of him as a father.
You'll want to book ahead online as a tour is required. The docents are excellent.
The studio itself alone is worth the cost of admission. Unfortunately, it is almost impossible to photograph (not because of any rules, but rather it's not configured in a way that gives you the kind of picture you might want). Just seeing it makes you want to work there. Having said that, several of the rooms of the house are quite appealing in their own right, with all kinds of clever touches.
As noted above, there are several other Frank Lloyd homes just around the corner. While they are not open to the public, you can easily see the exteriors and it is an elegant neighborhood that is pleasant to walk around. There is a self-guided walking tour, but you can also find maps online. The Unity Temple, designed by Wright, is also a short drive away.
This is a unique and uniquely American site that anyone with even a passing interest in Frank Lloyd Wright should see.
