After salvaging materials from pallets that we got for free from Jennifer's dad...
...we simply placed a salvaged 4x6 on the ground to make-level two pallets that would form the deck frame:
We then disassembled enough additional pallets to provide us with the boards we needed to fill-in the gaps:
Next we added our little bistro set and screwed it down to the platform as it's often windy here and we did not want anything blowing into the wetland:
That's it! Easy-peasy. Other than half-a-box of nails, we spent nothing on this project. Free pallets for all, we say!
