The "nope, don't use it yet - mansion" file can be ignored, it is not relevant. Knowing how it does not work would enable us to make a more specific determination of what went wrong. If nothing changes when applied, chances are it's a folder name/placement issue. Re-reading the instructions is not a bad idea.
(edit fixed misstatement)This mod is not necessarily compatible with all other mods (some smaller mods are compatible depending on order); the specifics have been discussed in this thread, but if you list any you may be using an analysis can be made. Also, my bugfix patch is not compatible with this mod as both change too much.
