So, I tend to agree that this house does not immediately jump out as ugly, and the suggestion that it is obviously flawed does come over as snobbish.
I'm not sure I mind the mixed stone and stucco that another comment mentions. It seems like a valid aesthetic style, especially with the chosen colours.
However, there are a few weird things I do notice. The double roof gable on the right seems unnecessary and unbalanced. And there are also many random windows in different styles, and in strange places. The ones below the double roof seem particularly obviously mismatched, and the window on the diagonal portion above the main door really looks out of position.
