Recommendations on new shop

I would make it as big as you can, within lot limits. Mine was 24 by 40. Make length and width multiples of 4, then there is no waste on cut off siding and sheeting pieces, which are 4 by 8. Wood stove with gas back up for heating. Insulate and drywall ceiling and sides. Big insulated windows on south side for free light and heat from the sunshine. Air compressor separate from building. 1 single and 1 double door. Put the lift on 1 side, prob at the single door. This gives you a wide open space at the double door. Wood frame construction? I prefer that over metal, for a heated shop. I would include a floor drain in or near the bathroom. Then you can always add a parts wash area there. Long workbench along the double door side. Mine was 2.5 by 16. Never big enough. Cover the OSB top with peel and stick floor tile, for an easy to clean oil resistant surface. Angle supports from outer edge of bench to where floor meets wall. This gives you strength and an open area under the bench. Sounds fun! Good luck.
