Boundless Intricacy

As you might also recall from the February 2008 feature, figuring out how to separate the indoor and outdoor pools proved to be a surprising challenge.

The swim channel under the clamshell was intended to allow easy access between the two pools, but the client (who knows as well as anyone how raw the winters can get in the Chicago area) wanted to be able to close the channel off when the weather turned cold.

That seemingly direct thought resulted in a three-year odyssey that led us to multiple engineers and system fabricators in quest of a workable solution. The irony is, what now appears to all the world to be a simple, retractable acrylic panel – perhaps the least visually arresting element in the entire project – was by far the most difficult effect to achieve.
