If it's my building, e.g. the building that I live in - I care more about the ease of maintenance and repair than any facade.

Because I spend 80% of my time indoors, and 20% working in the garden, so frankly don't even care what the building looks like.

Maybe only care that the property looks neat when it's time to sell.

As it stands, these studies are just cherry-picked navel gazing with extra steps. You can't design a study like this well. There are hundreds of thousands of buildings, and tens of thousands of variations of subjective preference. And all of those go out of the window as soon as practical concerns (like affordability) arise.
