Howdy, and congrats on beginning your new shop. The area of my shop is much like yours except my ceiling is not as high. As for suggestions, this is what I did. I made a scale drawing of what would become the shop floor as seen from above, also drawing to scale where each stationary machine would be located so as to afford sufficient work clearance between machines. In many kitchens, designs allow for easy movement between three much used areas (a work triangle), the sink, the range/oven, and the fridge. In the shop, a person could have a similar set up for three or so of the locations where most of the work is done, for example the table saw, workbench and miter saw, or any combination they felt would serve them best. Another thing you may want to consider is to run electrical conduit and rough-in boxes from your breaker panel (after the forms are built and the steel is laid), to where each machine will be located before the slab is poured, sizing the conduit for easy running of the wire gauge chosen for each machine, e.g. 12 or 10 gauge or heavier wire, after the concrete is poured. This worked out well for me as there are no wires on the floor to trip over or be in the way. IMO, dust collection is an important consideration, for it not only helps keep the lungs clean, but there is very little accumulation of sawdust on the floor or on your tools. My dust collection machine is in the middle of the shop, and it works well because the distance from each machine to the collector is fairly short. People with enough floor space might enclose a corner area in which to locate their dust collector so as to have it out of the way and also have less noise. Blast gates for each machine is an inexpensive but very helpful way of maintaining suction for the machine you are using. Good lighting is also an important consideration, even to the point that when they are all on, you have little to no shadows being cast on your work area. My shop has lots of windows, and I enjoy the natural light, however, I lost quite a bit of wall space for hanging jigs/fixtures/clamps, so you may want to give that some thought. I hope this is helpful to you in your shop planning stage, and I believe you will find that the construction of your shop is almost as much fun as working in it when it is finished. Good luck.
