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.
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.
