I'm about to begin construction on a home with a walk-out basement in Virginia. The current plan includes 2" foam below the slab. I'm not finishing out the basement right away but intend to add additional living space in the basement within a few years. I'll have slider doors in the walk-out basement, so my primary concern right now is whether the doors should be placed to account for subfloor installation. I'd appreciate any input on the following options:

1) No basement subfloor and place LVP directly on the concrete in the future.

2) Have the contractor set slider doors up 1" to account for future sub-floor installation. If this option is selected, what is the best material to put under the door frame to fill the 1" gap and to avoid rot, etc.

3) Have the contractor install subflooring for the entire basement at the time of construction

Also, does it make sense to put subfloor in the mechanical room, or should that be left with a concrete floor?

Thanks!
