The new Update now allows you to move your entire Lot (not just the House).
To start playing with this feature, open the Move Lot & House section (icon with 4 arrows) and select Move Lot.
This feature is more fun to showcase with a House bigger than the Lot itself, so we’re going to use the Yuma Heights 40×30 House on a 30×20 lot.
As you can see on the picture below, the House is too big for the Lot, but you’re still able to move it around, rotate and place it.
The green blueprints show objects and rooms that will be implemented into the lot, while the objects and rooms highlighted with yellow won’t be plopped on your lot.
I did this and it deleted my whole house
