Remove the mods folder entirely and try repairing the game. Make a copy of your save folder for backup. See if the game works and the house loads. If it does... You don't need to save, but if you do you will need the backup save folder because saving without mods and CC will remove all mods and CC from the house.
Put mods back and try again. If it loads great, if not then it is something in the mod folder.
Also try creating a new save. Keep mods in and see if the game loads to a house. If it does then the problem might be a corrupted save file. In that case use the load save option and try going back in time to an earlier save.
