Garage/Large Shed Project Planning

I'm looking to build a large shed, or what could be considered a small garage. I just bought a house with a two car garage under it. It is good parking space, and enough to do basic work, but I need more storage room. I have a Jacobsen tractor with a 72 inch deck, a snow blower attachment, and hopefully a power broom. I want to be able to store my Corvette in there in the winter as well. We have a lot of acreage (27) and I plan to build a large garage in the future, but that is at least 5+ years away.

I had initially planned on doing something 12x14 but I decided that I would outgrow it very quickly.

Here are a few things to consider:
1. I need to stay away from doing a concrete foundation or sonotubes. This is considered permanent construction and since it would be built within 100' of wetlands I would need an updated survey along with the hassle of the conservation commission. When a concrete foundation isn't used you can actually abut wetlands. Although this size structure still needs a building permit, which shouldn't be a problem.

2. I plan on digging down 6 inches, and putting crushed stone and weed block.

3. I'm planning on constructing the base of 2x6 PT joists sitting on (4) 6x6 PT skids running front to back. I was thinking that I could also go with 2x8 and just have three skids, thoughts? The skids will not sit directly on the crunched stone, but they will sit on 8x18x4 solid concrete keystone bricks sunk into the crushed stone. I have those left over from another project. I have enough of the bricks to make a continuous base under the 6x6 skids.

4. I was considering doing two layers of 3/4 marine plywood for the floor instead of just a single 1" layer. Thoughts? I need to have it be able to support a 1500 lb tractor and a sports car.

5. The location is about 1' 6" lower than the wrap around driveway. I plan on either making a ramp or just using crushed stone to create a bridge between the driveway and the garage door. The shed will be very close to the driveway so the details of getting a tractor and car in there shouldn't be an issue.

This is the design I was considering going with.

So you want to make the garage floor out of wood? And park a car or tractor on it?


Why not go with a pole style building? I don't believe they classify these as permanent structures in all areas.

I have somewhat of the same constraints with the concrete and also thought about doing a wooden floor. I've decided to go with patio paver bricks instead due to their durability and the fact that I'm also going to be storing a vehicle. Unfortunately I had already bought a good amount of 3/4" GC rated treated Plywood. I'll most likely use that on the roof then.

Yes, I want to do this because I want to minimize moisture while the tractor and/or car are sitting there. Using 2x8's 16" OC (2x6's will even be ok according to my load calculations) with only a 4' span between the skids supporting the joists shouldn't be any issue. Also, putting two layers of 3/4 plywood will help keep it stiff. I may put some bracing between the joists as well just to be sure.

There are a few reasons why I don't want a pole style building. The first one is I don't want a dirt floor and I can't pour concrete (even sono tubes) without going through the conservation commission due to the proximity to wetlands. As soon as I put in a permit to the conservation commission they are going to require that a new wetlands study be done ($$$$). This could literally add 25-50% to the cost with no guarantee of approval. :sad:
