Easy DIY floating ground level 10x20ft deck!

Our deck is about 8 inches off of the ground

Material list:
2. 2x6x10 for frame
2. 2x6x20 frame
14. 2x6x10 joist
30 joist hangers
Hot dipped galvanized 1inch nails
3 inch deck screw (tan color)
4x4 post
22. 5/4x6x20 deck boards

The reason I didn’t dig into the ground and use posts and cement is because I eventually want to raise the deck completely off the ground to meet right underneath my door frame ( so when I step out my door I land directly on the deck, rather than walking down steps) I wanted something temporary and easy to remove for when I’m ready to raise it off the ground. I realize that the ground may shift over time making the deck un-level but I’m ok with that because I would like to lift it up anyway.

This way was easier and cheaper to build it on the ground for the time being until next year
