The Glass House is behind the stonewall. The Glass House was designed by Philip Johnson, a world-famous architect. This building was his weekend retreat.
The structure is located in New Canaan CT and you are able to take tours of the house and grounds from April to November.
I have not taken the tour yet. However every time I walk this area I take a peek at the house.

Very neat house. I’ve never seen it except in magazine articles. If you’re ever headed to Virginia drop me an email. Mike
