Culture is enough to do that.
The people do not like glass and metal, it's cheap, the glass isn't safe, it is wasteful of energy to heat and cool. Stone is "natural". Skyscrapers are more cheap-outs, and inaccessible for many.
I can imagine a culture that disdains cheaping out on buildings, that thinks buildings are a form of art and not using stone, sculpture, highlights is ugly.
After all, the old institutions we admire most are all stone; most city halls and government buildings are stone or concrete. We love and fantasize about castles, stone archways, stone forts, stone churches and cathedrals full of stone statues and stone gargoyles and lions protecting them. Stained glass is art, a window is ... just a window.
The modern office building looks sterile and utilitarian, why would any self-respecting professional work in one? Do they care nothing about the aesthetic senses of their clients?
Just build it into the culture. It's like dress: We could all, male and female, children to the elderly, wear the same gray shirts, pants, shoes, winter coats, underwear, etc. Dress could be meaningless. But in our culture, it is not. We are entertained by dress. Dress expresses our emotions, our sense of self, we use it to look attractive, we like variety in our dress and appreciate variety in the dress of others. We use it for formality, suits and tuxedoes, frilly and other impractical dresses serve absolutely no practical purpose, they are strictly art, custom and form.
Stone buildings are a form of dress. The cultural expectation is you will NOT show us the equivalent of a T-shirt and jeans and sneakers -- Your place of business will be entertaining, it will be natural stone, with carvings, with sculptures, with marble columns, and statues or other stone art.
Or nobody will frequent your business, or rent in your building, no matter how cheap you make it.
Here's some kind of weird warehouse district, it's absolutely disgusting. It might as well be cardboard boxes!
