My (Rhavik) only "project" was a small camp site at the west end of our land. Since I'll only be on during free play times I don't expect my area to remain unmolested. I have baskets with grass armor, twine, string, and other components, some tools, and such. Use what you like, remove what you like.
A long time ago I made a windy path down the southern slope to the road and some trees to speed up wood gathering and other transportation down there. I was thinking some kind of path down to the river below Wandern's tent might be helpful.
If you guys stick with it for awhile make sure to throw us some screenshots of the improvements now and then!
