Are you referring to the doors to the right of the refrigerator? If so, those were reclaimed by the home owner (who is herself an interior designer). They were about one hundred years old and actually had to be cut down to fit the doorway because they were so large! I don't think too much is known about their provenance apart from that, but they were fairly ornate so they were likely to have come from a church or public building.

the doors with the wine on the island is what I was curious about. Maybe they're just glass, but it looks like a really fine screen.

Ah, sorry for the confusion there! Yes, there is a screen there but it actually isn't too fine. It's a little tricky to see in the scaled down version on this page but if you visit the following link you can view it at a higher resolution: http://fromthehipphoto.com/cherry-creek-home-two/
