Last weekend I put the down payment down on a shed. It's a 14x28 Graceland Portable Garage shed. Here's a link to it: http://gracelandportablebuildings.com/portable_garage.htm . It's a pretty nice shed, and is solid. However, it's just a shell, my job is to finish the inside. So here's the gameplan.... I'm going to separate it into 2 separate rooms, first, the shop area, where all my tools will be. Second, there's going to be an air-conditioned back room where I will store non-automotive stuff that won't fit in the house. The back room will be either 8 or 12 feet deep to accommodate all my junk with the remainder going to the shop. With the need to finish the building's interior myself, there's some questions I need to answer that frankly I'm having trouble answering. Cooling: Down South, it's HOT year-round. So, my storage needs to be cooled, that's non-negotiable. My issue is how am I going to cool it. I was originally going to get a through-the-wall A/C unit, frame a hole in the wall for it, cut the hole out and install it. But, I'd rather not put a huge gaping hole in the wall just to have the window unit go out a few years down the road and have to resize the hole for whatever air conditioner I can find at that point. Then, I discovered the world of split-unit systems. Here's a link to the one I was considering: http://www.homedepot.com/h_d1/N-5yc...splay?langId=-1&storeId=10051&catalogId=10053 . Using a split unit system, I only have to drill a 3" hole in the wall to run the lines through. Much more hole-friendly. My question, is how well do these split systems work? I've seen them in a couple local restaurants, but didn't know whether they were put there to supplement an existing a/c system or running solely off them. Do they cool well? The split-unit would cost about double what a regular through-the-wall would cost me, but I like the install and aesthetic advantages. Wall Covering: I'm not sure where I want to go with this. I'm going to need either sheetrock or plywood on the walls in both the storage and shop areas, but I don't know which way I want to go. I've never sheetrocked before, so I don't know how hard it is to hang and cut holes in, etc. For that matter, I've never hung plywood on a wall either. I'm a total noob in this area. Suggestions? Flooring: The shed has a plywood floor, but I'd like to cover it up with something nicer, more durable, and spill/stain resistent. For the storage area, I was thinking of simple linoleum or peel-n-stick tiles, but I think it'd look kind of tacky. Ceramic tile would cost a lot to buy and install, and probably wouldn't stand up to dropping stuff on it. For the shop, I was thinking maybe some sort of epoxy coating similar to what would be put on a concrete shop floor. Again, suggestions? Thanks guys, I'm so excited to get this shed!
