With the aging of society,special groups have had increasing needs of integrating into social life,and higher requirements on life quality,and the society has attached increasing importance to barrier-free design.Taking public rental housing for example,both circulation space and furniture design have to fully consider needs of special groups such as the seniors and the disabled.Barrier-free design in living spaces can help improve their ability of self-care,reduce their dependence on family members,fully demonstrate the"human-centered"design concept of public rental housing,and show the designers’sense of social responsibility.
