When I wanted to move my water purifier, I had to break all the foundations underneath it to destroy it. You should add a method to move structures without destroying floors/foundations.
Had the same problem. I also think there should be a way to "pick up" objects "on" the raft, like the water purifier, the cooking station, the crop plots, etc.
I'll second this. Once I built a second floor, I decided I wanted to specialize and move things around but I didn't want to just destroy what I had on the first floor.
Lorenzo, if you make a hammer then right-click while holding it, you'll see a bunch of things you can build, including stairs and pillars to hold up more flooring.
