The modern (now past) city model was about economy of scale: competing business in a small area means innovation, lower prices and specialization. Since such model do not exists substantially anymore cities have almost no purposes anymore. Suburbs where people live but do not have services also suffer. As a result the classic Riviera model where people live spread, but also find local spread small services survive and flourish. At that point who want to be in cities or suburbs? I fail to see ANY purposes to "convert offices to residential buildings".
