I have just moved into a new home with a double garage. The area past where the door opens (19ft x 10ft) has a 13ft high ceiling. I would like to construct a floor with an access stairway over this area for storage. It should be able to carry a load equal to normal household floors (whatever that is, I live in Ontario, Canada). One 19ft side must span the garage. The other three sides can be attached to load bearing walls or supported from the foundation. Is there a way to build this without a pole that is not cost prohibitive?
TIA, John.
