Kreinbrook, Aaron TylerHuman behavior, of any given individual or group of individuals, occurs within varying ranges of ability. Related to the differences in ability among humans are differences in lifestyle. Built environments that are designed for those of a specific ability range and those that engage in specific lifestyles prevent or limit the activity of others which exist outside of the targeted group of inhabitants. An inclusive, or "barrier-free," built environment is here proposed, one which promotes universal accessibility and accommodation. This thesis will explore the implications of barrier-free design as it is applied to a multi-family residence which takes the form of a housing cooperative.en-USThesisArchitecture
