I believe it's uniform(missing-middle(built form)) built form: function, shape and configuration of buildings as well as their relationship to streets and open spaces. missing middle: built forms between high-rise buildings and single detached homes which promote walkable urban living and fit into the character of many residential neighbourhoods, which "have gone ‘missing’ from many of our cities in the last 60 to 70 years."
