Background giant tree root grew in my plot while I was away gathering stone. I had bought the plot and set down a few blueprints and even built one furnace, and when I got back the damn thing was right in the middle.

@luminos77 Try placing down a charcoal blueprint in/around the root and that should make it disappear. Once it's gone, you can delete the blueprint and build normally.
