Wow, that AI is something! I'm drawn to the rendition with your current siding. The darker version the shutters don't look appealing so wonder what that one would look like with no shutters.

I like the third option, but what about the other 3 elevations? If you're adding stone, add it all around and not just on the front.

Is more modern the plan? Those first 2 look that way and if so then lose the shutters .When talking to an exterior designer understand stone added to a bldg needs to look like it is actually part of the construction which IMO means it goes all around the house and only up on the 2nd floor if that would have been stone to begin with. and for sure not on the top addition.In fact I would not do stone at all on this style of house . I also need to see the rendition with the garage added to understand your final plan.

I like the last one best, but without any stone. The front porch is really nice in that one, but it looks different in that rendering than it does IRL. The side near the addition looks recessed in the rendering.

I like option 1 and 2. The third option looks too usual. I love the darker color on exteriors.

Looks so nice with the bulkier columns! lovely house .. I am going to vote no stone

(I feel like all the stone veneer is enabling lots of stone wallpaper where it doesn't belong - but that's a me thing)

I like the second picture of the dark siding with the stone all way up on the front gable.

I like the last one pic.

They are all great! Personally I like #3. But I don’t think you can go wrong.
