I am in the planning stages of building a skid house that will also be used as a summer cabin at one of the Lakes resorts. The planning has been going well and I have a couple different designs/layouts in mind, but I am not sure what to do with my floor and could use some help.
I plan on building the base of the house out of treated 2x6's and then laying down treated plywood on top of that. I was then going to put sheets of 3/4" rigid foam insulation followed by another sheet of treated plywood. What I have been having trouble deciding is how thick of plywood I will need. Could I get by with 1/2" for both sheets since the total floor thickness will be 1 1/4" or should I go thinker?
I am sure I will be checking back here often with questions and will post pictures of my build process too.
Thanks in advance!

Still trying to decide on white oak or metal skids. I know the advantages and disadvantages of each and I think it will end up coming down to personal preference.
A 2 x 6 floor with 1 x 2 strips at 3 1/2 inches will give you room enough for 2 inch foamular insulation underneath 3/4 inch green treated plywood. Before the flooring sheets are laid, sub-floor adhesive is used on both joists and insulation. There's no need to sandwich insulation like you described. That traps moisture and causes problems down the road.
Use sway braces for the walls to keep your framing square over the years. Get trusses that will allow for an overhang of 10". Consider using metal for your roof. Always use real wood for your interior, whether it's paneling or tongue and groove. Use a moisture barrier and r-13 insulation before paneling.
T-111 makes the best siding material w/cedar trim.
Here's one of my 10' wide builds with a couple ideas for you:
