i decided to give the majority of my bonus from work($10,000) to my son and me for his birthday and a project me and him have been working on. we have a spare room in our basement. his room in on the other side of one of the walls. he wants to have his layout connected to his room. should i take down the whole wall or just have a tunnel running through the wall? this would take away vision of the otherside of the layout so we would be walking back and forth between rooms but a nice backdrop in painted on the wall would be nice. any help would be apreciated greatly. thanks
