(Hmmm.. posts 3-5 came in while I was typing this, but I'm gonna leave it as is....)

What was your original agreement? Weekly payments for work and materials expended that week? Every two weeks?

If there wasn't anything that specific, maybe it's time to call him and spell something out and put it on paper. Tell him you need him to get caught up before you can move forward. I'm assuming you don't have any secure outside space to put it if you're thinking about having him come pick it up. He also needs to be caught up (plus possibly some storage fees if he hasn't been paying for awhile) before you let him pick it up, IMO.

I once had a verbal progress payment agreement with a contractor who was enclosing my carport into a garage and putting a new membrane roof on my flat-roof 10X12 shed. He came by every Friday and presented me with an itemized bill for work and materials from that week and I wrote him a check.
