Is it an open basement or do you have an actual room to dedicate to building? Either way I'm a big fan of that epoxy "garage" floor coating, especially for basements if it's damp our would ever get wet.(sump pumps fail!) I'm pretty sure that would hold up to any spills you might have in the building process as well. Would be easy clean up too. Could do a portion of it for your build area and put in a transition strip if you wanted to install carpet/wood/laminate ect in the rest of the basement.
