Go navy blue on the back wall as well. When you do the deck, make the rail the navy blue but the spindles white (and the front as well). As far as the horizontal white boards, I think it just needs another row above the window. It would look good if the white was about 1/3 of the entire wall, but it's too narrow. Keep the boards white, add a row, and paint the rail spindles white to coordinate. I think it will look great. If you won't be sitting on the front, if you just add nice landscaping in the front, you won't need to expand to a large deck or porch there as well. You already have a couple decks to use.

Did you meant stone on ground? Or did you meant brick/rock venere?

I meant, like a stacked stone instead of the horizontal siding.

Thanks Darzy! That would look better with another row of white, if I don't do the stone there instead. Prob alot cheaper too. Also wanted to add that we probably will take down the side deck to make room for backyard access. Just thought a small porch over the front door would make the curb appeal better as it's such a box right now.

I do like the stone. U could get a sand/ gray colors.
