I'm looking for a way to build a second level for a single room. It's a spanish style home and I am trying to build a tower at the front of the home leading into an open courtyard. The entry tower will be open from the first level to the ceiling or exposed roof. The rest of the house will be single story. I've attached some close examples. I've tried to build a second story, but there doesn't seem to be an option for limiting by rooms. I am using Home Designer Suite 2019. Any Ideas?
