26x36 garage, side bay across the back 12' where the bike is parked all summer.
24x24 behind that, got all my woodworking and repair tools in there.
One drive in bay for the Roadie, snowsleds, ATV whatever I happen to be working on. Built it as a pole barn, so I can move the 9x7 doors anywhere I want. Strapped it and insulated with 3.5 fiberglass. The boss seems to think the 4" Wytopitlock cedar vmatch and white tile ceilings is excessive
Car garage is sheathed inside with that GP Smartside OSB siding with the primed T111 pattern pressed into it. Paints nice and is waterproof if you feel the need to powerwash the cobwebs out.
Heat with a full size oil hot air furnace that a guy gave me to get it out of his cellar. Considering a change to a Reznor propane as I have a pig behind the garage now.
I need to do something about the floor like you too. Looking at some industrial epoxy that they put on factory floors, but a lot of prep goes into it.
There are some stick down products I've seen in car mags, but $$ also.
Probably will do it with PPG expoxy kits from Lowes, have a chum that did his in gray w/blue flecks. Heated floor, salt water from the cars and it hasnt come up in 3 yrs.
Next house is going to have a daylight garage door for heated storage. I hate not having flat floor access to a 26x40 heated space.
