Yes, I have. Many times. Homes, office buildings, religious buildings, and other structures, including the SC Johnson campus in Wisconsin. They look great. They feel great. They work terribly.

The Johnson labs, for example, was designed to allow in lots of natural light through glass and glass block walls. Great for reading. Terrible if the people inside work with substances that react to light.

Again, great concept. Visually wonderful. But not well thought out.

I've been to the SC Johnson headquarters building in Racine (not the labs, as you said).

They are still working there. It took a lot of post-construction work to make it usable and rainproof. And it's beautiful, which you certainly can't say about 99% of the corporate buildings in use nowadays.
