In 1893 he acquired a large property in Boulogne-Billancourt, where he established this unique garden containing a variety of garden styles including English, Japanese, a rose garden and a conifer wood. This became a meeting place for French and European intelligentsia until the 1930s when, due to the Crash of 1929, Kahn became bankrupt. At that time the garden was turned into a public park in which Kahn would still take walks. The garden brings together distinct traditions (French, English and Japanese), as if to illustrate the utopia of a world reconciled, where different realities can coexist in perfect harmony.
