A unit building, also known as a unit house, refers to a residential apartment with a private kitchen and bathroom for every household in Chinese mainland, as opposed to a tube-shaped building and a unit household.

It is equivalent to an apartment in the west. Residents don't need to share space with others except in and out of their own units. Unit building protects the privacy of residents. However, some people say that this kind of apartment does not encourage neighborhood communication, thus promoting the indifference of interpersonal relationships in urban communities.
