I have an old camp 16'x24'...looks like hell on the outside but all the wood is good on the inside....just bare stud walls ...real 2x4' sits about 2 feet off the ground....can crawl under one existing do I put in a slab...without moving the camp ??

I've been thinking of cutting the floor out to pour......if you have any thoughts other than demo it.....I would like to hear them .....Thanks !!

I live in a house that was built in 1894, we have gutted the lath and plaster added 2" of rigid foam out side, insulated the wall cavities this cut our heating costs by 80%. About 2 years later we redid all of the ceilings in the house while doing this we installed a hydronic system to the side of the joists which heats the cavity and an insulated radiant barrier on the bottom of the joist before covering the ceiling, this cut our heating bill by about 40%. Heat source is propane fire places w fans originally, now an electric demand boiler.
