I do not know how to post screenshots, so I hope this works. You can copy paste this I believe.
I created this structure that is one wood block on the bottom. It is 16 wood blocks wide on the top. The few missing blocks in the center would cause the structure to fail.
I went as far out on the top as I could. That's 11 blocks out I believe. There was nothing stopping me from going higher. In case the screenshot doesn't work This
structure is one wood block at the bottom. 22 wood blocks high. 16 wood blocks wide. extends out at the top 11 wood blocks. Yes it all sits on one wood block at the bottom.
