this space is going to be an exercise room so there is going to be a lot of extra weight on it. I'm going to frame the inside of the hole and lay down plywood or OSB.
There are a couple issues. First, the border around the hole is slightly raised, about 1/4" or slightly less which shouldn't be a problem.
My primary question is should I lay down 1x2's or possibly 1x3's because of the weight or skip that all together and go with a dimpled subfloor then plywood/OSB on top?
