Welcome to GT40s Ron...
It's darned hard to build stuff out in a cold shed.. I know and have done it.. Too many years of working in the cold, laying on cold floors have taken their toll and I'm not a youngster anymore.. But all that said, there are a lots of smaller tasks that can be done in the basement of the house or even on the living room floor. Lot's of planning that can be done at the dining room table.. Good luck with your project!
