How about a lean-to?

One of the most primitive and easily constructed shelter a person can put together is the lean-to. It seems odd to me that the first structure you build in the currently evolving game of Rust is a stone foundation with fully hewn log walls. There aren’t many advantages to a lean-to in real life, other than potentially keeping you a little bit drier and warmer (not much) but it only takes maybe an hour to put one together compared to what would be a multi-day project building a stone foundation with hewn log walls.

Just a suggestion, I do think the more primitive side of the player building spectrum could be expanded upon.
