Well I wish I could afford what everyone has on their wish list. If I waited til I could, the list would have changed and still couldn't afford it lol. I want a place big enough to hold 3 pieces of machinery. A tractor or 2 and a combine with room to walk around and room for benchs welder etc. Floor heat is a must. A separate room for your compressor is a big one. A guy who owned a automotive garage in town yrs ago had his compressor in the basement of the office part. It made for an environment you could talk easily in regardless of what was going on. Have retractable 1/2" airlines on all walls and 110v retractable cords. Makes sweeping and cleanup a breeze. Rolling benchs are a must for me. Good lighting is a must. Windows will help greatly with light from the side but wall lights half way down or lower are key. It seems you can have all the lights in the world up above but lift a hood or crawl under something from the side and it is dark. My shop I want a wall mounted electric pressure washer with a retractable hose reel. I don't need a separate wash bay with floor heat. I don't use natural gas or propane so leaving a door open in winter a few minutes to exchange the air after washing stuff is just what I do already in my house garage. Round bales in a boiler heat my yard so heating is the cost of running a small electric pump to circulate the water and a bale every 36 hrs currently. I hope with a shop added I can get 24 hrs and a cleaner burn. A bathroom will be in order and my office will be small. Enough room for a computer and a big dry erase board microwave and tables and chairs. A big calendar with naked chicks to keep the wife away on my beer fridge, which will hold a bottle of captain spiced and some mix.
