Giant oven in front of lot that I can't remove

@moonnyxx Best option is to use mods for this. You should be able to remove them with either TOOL or the allcheats mod which will give you the option to destroy the object.

I do think either should work even with supersized objects. If it doesn't work, let me know, there's another (a bit more complicated) way.

You can also try have an kleptomanic Sim steal it but I don't know if that works with supersized objects.
