How to set the different elevations at each corner of the ground level?

[maplelandhomes]

I am new to the sweet home 3d software. Currently, i am designing my house and the lot is sloppy. How can i set the different elevation at each corner?
Example:
Facing at the front of the house:
1.Corner left is 2 feet below the ground and
2.Corner right is 4 feet below the ground
Facing at the back of the house:
3.Corner left is 3 feet below the ground
4.Corner right is 5 feet below the ground

Thanks everyone in advance

You probably need a workaround, if you look around the forum, you will find many threads discussing this, e.g. 4817 , 3335 , 6060 , 4450 - and then quite a few...

Depending on what you want, triangles or other geometry may help. ok.
