I know there is a word for this kind of person, but I can't remember it. What kind of person would buy a house with a beautiful garden in the back, and replace it with grass?
A lush garden with statues; a koi pond; fountains; lanai benches; all kinds of flowers that attract hummingbirds; flowering trees; trellised vines.
Only someone who did not have a well-developed sense of beauty, someone who had no aesthetic sensibilities whatsoever... there has to be a word for this kind of person.
Ingrate doesn't quite cover it. Neither does ignoramus.
