Environmental design which supports worthwhile aged lifestyle was proposed in a model and divisional graph. The model consists of 3 main elements; lifestyle purpose, the objective of achieving that lifestyle, and the action by which that lifestyle can be created. The divisional graph consists of two major axes; the objective axis (containing the public service field and the personal interests field), and the activity axis (containing the individual activity field and the group activity field). As expressed in the model, these fields overlap forming 4main categories; belonging, co-existance, independence, and interchange. By applying current worthwhile lifestyle activities to the model their functions in terms of the graph's fields can be validated.
