Complete newbie here, so I apologize if this question is lacking in detail. I am starting to do some research on finishing my basement - I've never framed anything previously. My house was newly built and we moved in in Dec 2017. My foundation is poured concrete. All of the exterior walls are framed, insulated and then wall wrapped.
My question is - would I need to frame walls inside this existing framing / insulation / wall wrap OR could I just hang sheetrock along the framing already in place?
