The transition between the guest bedroom and the study used to be virtually raw wood. We think the main back door came off the guest room, therefore the threshold and doorjambs are much wider here than in interior doorways. As you can see, the study is panelled in knotty pine, so we're thinking we'll turn this into a jungle or safari-type room.
