Arthur Dunn asked the Olmsted Brothers to design a 'country place' in 1915. The landscape design took advantage of the sloping ground, the woods and the views of of Puget Sound and the Olympic Mountains. Arthur's house does not survive but after his death in 1945 new homes were built for his 3 children and the Olmsted landscape is in good condition. One of the children, Edward Bernard Dunn, became president of the American Rhododendron Society. He converted the garage building into a house and made a 2.5-acre garden.
