Can you post a picture that shows the whole house? Hard to tell how "chopping it in half" with color will affect it without seeing the entire thing.

If you are going for height, make it all one color. If you want to shorten and elongate the look of the house, use two. Sort of a basic rule, but without seeing it all, hard to tell.

The colors look nice together. Not sure I"d do the porch wall stone. It's getting a little busy with the pavers, the stone, the shakes and the siding.

Again, an overall pic might change my mind.

Thanks, it's hard to get the entire house in because of the trees in the front. To the left is just an attached garage that has the same green siding on it. I'll see if there's a better angle from the other side or something. Thanks again.

Thanks for the pic. I think you could do the bottom portion in shakes but if you do, I wouldn't do the stone around the door. Nice house!

Have you considered painting the garage doors? You really don't want to feature then and keeping them white makes them pop out.

Absolutely going to change those garage doors, want to wait till I get the entry door replaced so I can see if I can sort of match that up. Lots and lots of changes. Basically going from a rectangle house to a rectangle house that looks different. I should probably send you a picture of what we started with.

Something I did for a previous question.

Note the white trim -- the corner boards and band dividing the 2 types of siding. See how the band is raised making the first floor visibly taller than the 2nd. And you really should have something visibly separating the two materials, even if they are the same color.

All these small details need to be considered prior to making mass changes.
