I never thought about a floor drain, may have to ask about that one. As for heating I am thinking of just adding insulation up in the roof and then in the walls and then rock it. Then put in a larger heater up in a corner at some point. I never thought about in floor heat and I wonder how much more that would be.

We are going to have an attic for storeage. We are using a roof design that will give us 5 foot high walking space down the center and then narrow out 8 feet on each side. Thus, it will have a solid floor on at least the rear section, possiblly the whole thing.

On anoter note, I am going to have it wired up for 30/50 amp (not sure which it is) so I can have an air compressor in there and at least have the ability to run a welder and such if it ever came about.
