If I make another one (which I probably will) I would put some more storage drawers in the bottom part. Currently it has a large box with jig nick nacks - cam handles, t-nuts and the like but still has a lot of wasted space.

In a smaller workshop you can make the overall size as big or as small as you want.

Just remember that if you go taller you will probably need some heavier junk down the bottom to stop the 'tower' from toppling over especially if you plan on moving it around your floor space.
