I added (with help from a few friends of course) a 14' x 24' extension to my existing 12' x 24' workshop.
This gives, me a full 12' x 24' inside space for woodworking, all of my lumber and raw materials are in the new section along w/ lawn tractor and other assorted lawn things.
Half is a deck, so I can roll my machines outside to work when the weather is nice.
I used a brilliant metal spike collar holder for the 6" x 6" posts, as good as concrete with the benefit of not having to dig holes.
Just need to do a new ramp to the extension (pile of wood on deck), then it will be done.
