ROM Hack Animal Crossing editing help

Hi people. In Super river editing, you can replace the walls of your town become river. How do I access a map that lets me put buildings in that area as well? Thanks.

Just delete the building you want to remove and add it where u want it.
As you may see, some of the buildnings contains some pixels, and the thing you add is only 1, when you load the save and save it again, the 1 pixel will automaticly turn into as many as it suppose to be. Good luck
