Lots of great ideas here. I had a quarter of the basement for my salt water fish setup and went from that to reloading. I used the same table built of scrap material and really like it. I had the two bar stools second hand from the folks so I made the table higher (like everyone else). I like the way I can get all the way around it. Makes it more flexible for larger projects (cleaning and gunsmithing) but still enough room to spread out. You could substitute slim line shelves with doors for the open shelves I made and obtained from others. I wired all the plugs to two seperate circuits for the fish stuff, but they work wonderful for additional lights and trimmers and the like.
This is the setup before my wife moved in and said the fish tank had to go.
