Afternoon on a hill in Boston

I'm struggling to work out the strong light effect vs the very large facade of the house that's in shade. Details in the shade shouldn't attract much attention, much less be included at all.  Yet, I find the large side of the house didn't play as a strong, solid mass when I left all of the details out.  It just looked unfinished, as the remaining painting did have a sense of smaller shapes representing details.

I am taking a week off soon and I'll be letting this sit in this state for now.  When I come back, maybe it will be clear to me how to resolve this.
