Our diy project for converting our crawl space into a storage area after our sheetmetal shed was crushed by 3 feet of snow on it. Columns of decorative rock was installed. Had to use the car jack to rise porch 1/16" temporarily to get the stone in. The louvers can be closed for the winter time. The other doors have a permanent screen. In winter time, reflective insulation is installed over screen.
Since this crawl space was converted into storage area we needed not to install new shed, so the concrete slab the shed sat on needs to be dug out and a firepit/patio can be placed there instead --> A future project
