@FiretheSky As far as I know it's not possible to move the lot grids in Sims 4. You can build your house/structure anywhere inside the existing grid and there is a mod that allows you to edit outside the grid, but that's about it.
THEN WHY DID THEY PUT "MOVE LOT" AS AN OPTION????? ):<
AND my mods folder is corrupted!
@FiretheSky Yeah the "Move Lot" option allows you to move all objects on the lot to a different position within the existing grid. So if you have a house + landscaping (including all plants, rocks, and terrain paint) on a lot and you wish to move everything a few spaces to the right, then you would use the "Move Lot" option. If you want to move only the house and leave all landscaping objects where they are, then you would use the "Move House" option instead.
It's not like the World Edit function from Sims 3 where you could create all new lots on the map.
