Wanting to build a garage (Need advice)

Cdx plywood has same exterior glue. And yes, the electric; 200 amp, you can't have enough receptacles. And need 220 service. A small 2 ton heat pump is great. Just get some ductboard, and build a plenum at the back, and put 4 vents in it. Damn air compressors are loud; Farmhand from Tractor Supply is quieter. Soffit vents, turbine vent on roof. Shoot every squirrel in the neighborhood, as they see a future home. Never enough windows. Just weld and install rebar cages.

Yes, it does but it is wood on the outside with no protection. Put both out in the weather for a while and see what one deteriorates fastest.
