those poles in the middle that support the house are (I believe) called lollie poles?
I think Alan is right about gotta know the dimensions.
How big is the wood storage area? How big is the finishing room?
I dont know how much wood you store or how much floor space your using for the storage area.
I have approx 2000 give or take 100 bf of wood in my garage.
IF you dont have more than that, I would build storage along the top edges of all the walls in the basement. Keep your tools and supplies on shelves underneath the wood, but since most of the time the wood is only stored and not accessed every day, it needs to take up the least useful space in a restricted area shop.(this is only my view on things)The top 1 or 2 feet below the basement ceiling with either store bought or homemade arms extending 16-18 inches off the walls would hold alot of wood, freeing up the floor space you use for wood storage.
Then Id move the finish room away from the far end, move it next to the stairs, move your assembly tables and junk the table and stools marked tom and larry.
Place all your equipment in one large working area, positioned the most important next to each other, like jointer and planer close to each other, table and crosscut , use the length of the crosscut table to house your small machines, if they arent used alot, if they are, just build the crosscut bench further out and house the machines there. Open the shop to one large area, dump the walls, just one one side where the finish room would be. Ok, Im going to pack.
