I own all of the Stuff, Game and Expansion Packs that are currently available on Origin (05 November 2021)
If you want the rooms to show up as in the preview, you will need: Cottage Living, Country Kitchen, Cats and Dogs, Journey to Batuu.
If you are going to place the rooms in the lot I am uploading as well, check for double windows, doors and all that is attached to the walls.
I used the cheats bb.moveobjects, bb.showhiddenobjects and used items from the debug menu. Please use at least the bb.moveobjects before placing the lot. After downloading and installing, the rooms can be found in My Library, under the Advanced tab. Make sure to check include custom content.
