When Cramer started his own business in 1929, he mostly designed private gardens for wealthy clients and perfected a romantic, rather picturesque style.
The abstract basic conception of his gardens, the renunciation of superfluous decoration, and the use of concrete and geometrically shaped elements caused considerable irritation among his professional colleagues and added to his international reputation.
Kassler described the design: ”Triangular earth mounds and a stepped cone were precisely edged, grass-sheathed, and doubled by a still pool.
Many other remarkable projects by Ernst Cramer built in close cooperation with some of the most important Swiss modern architects and two gardens designed for houses by Richard Neutra do still exist.
With his courageous gardens he also helped shape the profile of modern Swiss landscape architecture and strongly influenced the work of young successors such as Willi Neukom, Fred Eicher, and Dieter Kienast from Switzerland.
