Just realized I put “interior” for the exterior walls in the post. There’s no insulation. My parents tried the “non-invasive” spray insulation by a company but it bowled out some of the walls and outlets after expanding and really didn’t look nice at all.
We have 2 trees in the front yard already. One medium and one large. The large one is dying and I will eventually replace. The 3 large trees across the street do help for early morning in the meantime.
