Abstract
The construction of garden cities in Belgium was started after the First World War as a social housing policy of the Belgian government. Among the garden cities, le Loigs in Brussels has been steadily constructed by a semi-public body that is called “cooperatives de locataires (tenants' cooperative),” and its excellent living environment has been preserved for about 80 years. As a result, it became a housing estate that is highly valued by citizens in Brussels today. Its history, current situation and the ways of living environment preservation provide us with useful information about how to preserve a good living environment of housing estates in Japan.
