In order to move or rotate the buildings you need to click on the yellow dividers icon in the lower left corner of the game screen:
Then choose an option:
- yellow arrow - return to the main menu;
- arrow pointing to the backpack - hide the building into the Storage (not applicable to some of the buildings);
- house with the arrows beneath - move building (also not applicable to some of the buildings, but to most);
- house with red cross - delete the building (not applicable to all of the dwellings and some other buildings).
When you choose to move the building you just need to click on the building, drag it anywhere around the map where it glows with green and then click once again when you find a spot for it.
