Abstract:The existing all-age communities mostly create their own exclusive public spaces for groups of different ages, and the differentiation of space is not conducive to the communication and mutual benefit of different generations of people. Intergenerational integrated all-age communities are the development trend of a harmonious society. However, they are faced with multiple challenges such as complex intergenerational needs and dynamic changes. This article specifically introduces the concept of inclusive design and community symbiosis, and proposes a construction strategy to meet intergenerational needs and adapt to the life cycle. It is expected to subdivide intergenerational differences and integrate spatial functions at the horizontal level, promote intergenerational inheritance and community symbiosis at the vertical level, and build a sustainable all-age community that promotes intergenerational integration.
