How to Build a Floating Deck
Intro: How to Build a Floating Deck
Here I will show you how I made a floating deck. The advantage of a floating deck is that it is possible to be moved to any location in the yard. This is by no mean a new Instructable, it was done before by TimBTodd. The deck that we built is 12'x12' and is supported by concrete deck piers.
STEP 1: Materials
8 - 2x4x12 treated studs
30 - 5/4 x 6 x 12 treated lumber
10 - concrete deck piers minimum
2x4 stud steel reinforcements
Galvanized 3 1/2'' nails.
Extra cinder blocks and bricks to level the footing.
STEP 2: Building Your Deck
I started by nailing four studs temporarily together to make a square. Then I nailed the other studs to the frame I made using the metal reinforcements. I used a square to make sure that every stud was parallel to each other. When the frame has been completed we moved the frame where the piers were.
The ground that we picked for our floating deck was uneven so I had to play a little with cinder blocks and bricks to level the frame. Once I was finished with levering the frame I could start nailing the planks to the frame.
We left some spacing between planks to allow for expansion during hot and humid days and for rain water to filter through.

Can this be done if the ground is sloped? If yes, how would you level the deck as all of the deck piers are the same size? Would you have to dig a hole to set some of the piers into where the ground is higher? Would this cause issues with ventilation?
We have an area against the back of our house that we wanted to build either a raised patio with pavers or lay concrete, but we have too many electrical/cable/phone lines that come into that area to be able to dig deep enough. We also cannot add dirt as there is a door to a utility closet. Just wondering if a floating deck might be an option since we wouldn't attach a deck to our foundation.

It depends. If you are going to use it for an inflatable pool, the weight of the water leaning on one side of the pool walls will end in disaster.

Could this be built to place an above ground pool on? our backyard has a slope and this seems easier than trying to level the ground where we do not plan to permanently reside. the size of the pool is 16x48

You need to consider the weight of the pool with the water. It might be better to level the ground.

8' is a really long distance to span a 2x4.

8 feet for 2x4's is fine for a project like this. You could go to 10 feet as well, but that's pushing it with 2x4's. I am building a similar design deck, and am using 2x6's because of the length spanned, 15-20 feet. Because it is "on grade" (not elevated) the twisting won't be as severe. If I was going above grade or with elevations, you would want 2x8 or 2x10. 8 feet for this purpose is fine. As added piece of mind, you could use joist hangars. Additionally, your rim joists (the outside frame) could be 2x6's with carriage bolts. However, that might be considered over-building for a project like this.

It's not that kind of deck. I built mine on a slope next to the house. It is supported by pieces of 4x4 treated lumber standing vertically in the deckblocks. I had my doubts, but it ended up being incredibly stable. The longest vertical length I used was 30 inches.
You do NOT attach this TO a house, although it can be right next to a house. The deck will shift up & down a little with the seasons. Your house does not because of the foundation. Moving object connected to non-moving object=problems.
The deck block website has great install info and a DESIGNER program. Tell it what size deck you are building, and it gives you plans and a lumber list.
