Yea, that's a beast, all right... It seems that your proportions are a bit off.
The front of that house that juts forward is only 1 floor with an attic room. Use a steep gable with a hipped front piece and add a dormer for that. That room won't have walls.
The main house has a true second story with a 3rd floor roof. Make a second story for the main part and then a 3rd floor gable roof. You can move your lower story rooms out 1 click and add steep gables for those peaks.
