Excited about the newest roof garden at New York's Rockefeller Center, manufacturer Henry Kaiser engaged landscape design company Osmundson & Staley to project a rooftop garden near the firm's head office. Ted Osmundson conducted contract negotiations and acted as a link to the client, while David Arbegast designed the garden. The Auckland Planning Commission provided the firm with multiple options ( current zoning by height, retreat options, approval to backfill part of Lake Merritt for site expansion) in return for a substantial landscaping programme.
Consequently, 90 percent of the territory of the Kaiser Center is paved with houses and 60 percent of the territory is also improved. The garden was established in 1960 as the first "real" roof garden in the United States. In the difficult conditions of the garden used materials such as aluminum and cement, produced by Kaiser Industries for numerous large-scale development programs worldwide.
The project includes a big mirror pool with multiple little fountains, wood bridge, wavy grasses, a system of curved pathways, benches and an extended vegetation range consisting of 42 matured samples of trees, large bushes, soil coverings and herbaceous plants.
