The glass doors were salvaged from a cupboard in the original kitchen in this home, but the same look could be achieved with old window sashes. You could start by checking at architectural salvage places if there are any in your area. Thanks, Emily

Sent this picture to my builder...going to do the same...Yeah! Love it.

If you are unable to find a salvage piece, you can get a similar look by useing a french door, similar to these designs
