1933 Sorensen met Henri van de Velde through a client R. J. Wilson of "Dean Park". Wilson encouraged van de Velde to buy the Everglades property and engage Sorensen for the design of the garden. At everglades he paid homage to the magnificent views of the Jamison Valley below and to the Blue Mountains beyond. The Terraces he constructed were accordingly aligned with the natural slope and to take advantage of the views in a way, which did not allow the scale of the scene to overwhelm the garden. He held that the form of the garden was more important than colour and considered that Australian gardens generally were only interested in colour with the result that the form was often neglected. Also unusual for the time was his retention of native species such as banksias and eucalyptus within the garden. As few nurserymen were at that time propagating native species, he tended to draw upon the palette of exotic species with which he had become familiar in Europe, many of them he supplied from his own nursery or imported from around the world for the particular project. Trees and shrubs were always seen by Sorensen as the most important elements of a garden and were always placed to create a feeling of mystery as to what was behind them, as well as giving the usual feeling of enclosure and shelter. The idea of development over time is a commonly recurring theme in many of his gardens and displayed a profound awareness of the ecological impossibility of fixing the character of a landscape permanently in every detail. The aim was to create a final landscape, which, although having different qualities of beauty at different times in its development period, would achieve a state of ecological balance in which its continuing maintenance would be relatively minimal. This planned continuity of change and development over many years was quite revolutionary when Sorensen began his work and even today is not always accepted. There is little visible evidence of the immense physical difficulties encountered in building the garden. Construction took place before the days of heavy earth moving equipment and consequently all earthworks and the movement of the heavy stone were carried out by manpower alone. Fortunately for Everglades, the Depression was at its height and manpower was readily available albeit unskilled. Sorensen saw the first task as deciding on the qualities of
