storage building wood deck build

[312InchMagnum]

bought a little 10 x 14 metal shed kit from lowes to store outdoor equipment, etc...first off i know this isnt an ideal storage shed, but i will only be in this house for another couple of years and just need something to get me by for that amount of time...i plan to build it on a treated wood deck on cinderblocks (have about 12 sitting in backyard)...ive built a smaller wood deck about 10 x 6 before out of 2x6s and 2x4s...turned out great...i plan to use 2x6s for frame and i'm thinking 3/4" treated plywood for decking...im assuming this should be strong enough...plan to dig and lay gravel under cinder blocks first and level them all out...the area the shed will be stays pretty high and dry even during heavy rain...ive never built a deck this size, but im pretty handy with minor home improvements, etc...just got done trimming my house, installing new doors/frames, etc...just seeing if anyone else has done this or has any tips/tricks, suggestions, etc...thanks

I wouldn't use the plywood for the decking. Just my .02, use some 6'' decking boards.

the treated decking will be fine, but will probably cost you more than treated deck boards...I bought two of those same sheds a month ago. Got one built and gonna start on the next one in about a month........

Use either 5/4 treated deck boards or regular 2x6 treated for the deck floor, not the plywood.

Why not use plywood decking? It's gonna be off of the ground a minimum of 8" with the cinderblock, so weather really isn't an issue, I think the way to go is 3/4 decking, walmonized (water treated/pressure treated)

Personally, I don't think you need treated decking, as the deck will be inside (weather protected) and well off the ground, as you describe it. I'm assuming the siding will lap over the edge of the decking and be attached to the 2x6. It wouldn't hurt for the decking to be treated, of course, but would probably be an unnecessary expense, especially since you only plan to use it for a couple years.

Edit: Keep in mind that some of these guys would have you building the Taj Mahal of storage buildings. But I don't want my lawn mower and weed eater to have a better house than my own!

x2 Most subfloor in homes is 3/4" T&G OSB. Built a 10x16 about ten years ago with OSB and the floor is fine.

I was kind of thinking of building a couple feet extra around the actual side of the building in case I want to put things on the edge. So in essence a 12 x 16 or so deck for the 10 x 14 building. That's why I mentioned treated wood. Yes or no? Also what's the main difference in ply vs osb

The plywood is going to catch water around the perimeter of your building and the water will find its way inside. I would personally build your base the same size as the building where you can overlap or flash around the base to keep unwanted moister out. You can get by with 3/4" CD plywood for the decking as it has exterior glue to keep from delaminating, this will save you around $15.00 per sheet.

I definitely would NOT do it that way. If you want unenclosed decking, build it separately and attach it to the frame below the bottom edge of the building siding so that all rain that falls on the deck is shed below your siding and building floor. And for that portion, I would use decking boards, making sure the grain pattern is downward (like an umbrella) and space them just a little apart.

Edit: This guy says to lay deck boards bark side down. The opposite of what I was told, but... http://homerepair.about.com/od/yarda...deck_board.htm

If you are putting the shed on the 3/4 for the floor support it will be fine..If you are building a deck to walk on before entering the shed it needs to be deck boards..When people see deck most think of a deck you walk on..

You will be fine building it this way. I was worried about water going underneath so I ordered the weatherstripping mold that they use on trailer house windows and doors. I water tested it with a sprinkler and no leaks. I build for a living and treated tounge and grove decking will work just fine for this application. I am guessing you bought the metal building Lowes had on sale which is the same building I just got done building.

If I am correct he has a metal building and you can't build it this way.

I would not build it bigger than the structure and use Advanteck tongue and groove decking . It is an OSB product but very sturdy and it holds up better than regular half inch OSB. 2x6 should be fine for the frame. You might want to use treated for the exterior frame though,

Doh! I didn't realize he was talking about a metal shed. I don't have any experience with that, so you can probably pretty much disregard everything I said.

I have a small metal building built just like you are talking about, I had started to build a regular wood building and that all faded after I had built the floor, I have 2' on one side and the front extra, I built covered shelves on the side and have the front for entrance, Keep it painted and it will help it last. Mine is treated plywood and I have not had any issues with water getting in, I wish I would have raised it up a little more. Mine is close to 5 years old with no issues yet
