I have a new project where I want to make a pantry in a utility room space that is currently occupied by the clothes dryer. I intend to move the dryer across the room and stack it on the washer. The space is 32 1/2 w x 36 d x 96 h. I have a simple plan to install shelving on the 96" wall and that won't be a problem. I want to add a bi-fold door but there currently isn't a door frame in the space. How do I add a door frame for a bi-fold door? I've added a few pictures. Those are standard 12" cabinets and they will come out. Will I have to tear out the drywall to build a door frame?
