Hold on ill try to get some better pictures
Ok. Can you depict (or at least describe) how this room works (where is the entrance door, where are windows, etc)? If so, design recommendations can easily be made. If not, anyone can cut up a room.
Understand that after division, you have multiple zones that need to be treated separately regarding humidity/temps et-al. However, you have enough space to set up a really nice op.
