I have a 91" x 91" area of entry into a room I'd like to make into an office. What are some inexpensive ways I can install some type of French Doors or other door system to fit this area? Would I have to add more drywall? Any idea of cost for this type of project?

we have an enclosed laundry area the size of a deep closet that does not have any doors on it at this time. to control the noise from the machines we are considering putting in doors. the closet does not have any ventilation, except of course the dryer vent is ducted down through the floor and out to the exterior wall of the house. my wife thinks we need to have louvred doors because she's worried that without louvred, the lack of ventilation while the machines are running will be bad. my concern with louvred doors is that they will not control the noise and also they will collect too much dust and lint, and be difficult to clean. are louvred doors necessary in this application? would you experts recommend them over non-louvred doors? please settle this debate for us thanks for the advice kevin
