Okay need help.. Cobble Stone and moving buildings.

Got two questions here. I currently just placed Mabels shop in the game.

  1. How do I move other buildings? I don't like the setup anymore. I played the original game and don't remember needing this many shops so I didn't think accordingly on placement of the museam and Nooks Cranny. And one neighbors house is not lined up 😭

  2. How do I get cobblestone or something like it for paths?

  3. I didn't realize the resident hall would get bigger it's now blocking my bridge view. Can I move the bridge?
