I built an out building that is 28X30, half is for my tractor, 4-wheeler, garden tools, chain saws and such. The other side is a dedicated shop that I made initially for my bow making operation. I built the shop in about 2005, building costs in N/W Alabama were low at the time and I only have 19K in the shop building itself.
I have a permanent archery range and 50-yard rifle range complete with bullet trap alongside my shop.
The shop has plenty of outlets, both 220 and 110, it is well lit and insulated. I have a wall unit that will heat and cool but lately I have been heating the shop with 2 small 1500W space heaters. I have a dust collection system but put the dust collector in the adjacent tractor side to keep the noise down in my shop.
My 14X30 shop looked huge until I started filling it up with a variety of large power tools, when it is cluttered it is way too small but a good clean-up and it is just the right size again. I am continually adding shelves to keep stuff organized.
I made the workbench strong and heavy enough that it won't walk across the floor when I am doing some heavy drawknifing on a tough osage bow stave. Being a lousy cabinet maker, I bought precut drawer units from Lowes and built my workbench around them. The Goex cans date this picture, it was several years ago.
