Sorry if this is a dupe.
I am buying a 2 bedroom condo and have the space to cut off part of the living room and buid a 10' X 10' 3rd bedroom. The only problem is there will be no access to the outside to have a window. I know we are dealing with fire and air quality issues, but is there a way to go around this? I would be able to install at least one central a/c-heat vent and it will have a ceiling fan as well. What are the drawbacks here? Should I go ahead with this?
