I have a 30ishx40ish enclosed shop, with 12 ft eaves on the long sides & a mezzanine over 1/3ish of the inside, and still want more space. My thoughts are shelves and bins for all hunting stuff/seasonal activities, anything larger than a bin goes on a pallet/pallet racking (make them ~2' lower than ceiling height). Toolboxes/drawers for all hand tools, shelving for power tools (or hangers for the common use items), dedicated hydrocarbon storage (oils, gas, etc...), at least 2 large metal-topped workbenches and 1 wood topped. Bolt bins/Fastenal bins for everything from bolts to vehicle fuses to zip ties to hydraulic fittings. As much lighting as you can afford, same with power & outlets. Air hose on spool by front door, hard plumbed air in rest of shop with shorter hoses, biggest & quietest compressor you can afford too.
