Perhaps keep the entire house as stucco.

Hi Steve & Shannon,
Your house elevation appears to be simple, elegant. and lovely. You have several different features going on now with the exterior; roof lines, windows, shutters, balcony, turret etc.
I would suggest that you limit your choice to a maximum of two exterior sidings. Having 3 or more will make the house look choppy no matter how great they may look together.
You have a fabulous design already and if you want a little more drama choose door, shutter, fascia and window trim colors that would add to the appeal with out overtaking it with even more exterior elements.
I hope this is at least a little helpful. Best of luck with your new build, Jerome

Its hard to make a suggestion because its all about what appeals to you. take a look at this house....just used this stone.

But I have also see a mixture of bricks use on this facade and it looks great as well.

The turret and bump out on the right would look good. Brick will need to be supported.
