I dont know how big is the print processor, but it looks like it is outside the room ( if I interpreted the diagram correctly). IMO I would move the print wash to the north end, take away one sink and put the enlarger and the print processor together. I can assure you is going to get old to move around the enlarger to put the print in the processor, that is one mistake I did with my darkroom, I placed the tray and sink too far from the enlarger/printing section. Other than that, it looks very good. I like the exhaust system.

BTW, make room for some shelves and book case. I am sure you will need them.
