of "Sospel" at Leura. He also improved an existing garden in Leura, "Leuralla". Sorensen's garden designs influenced other gardens in the Blue Mountains, such as "Benison", at Leura. Sorensen redesigned and expanded an existing garden at "Mahratta" at Wahroonga, in 1925 for its then owner, Gerald Allen of the mercantile firm Samuel Allen & Sons. After 1930, Sorensen also worked for the next owner of "Mahratta", James Joynton Smith who, as owner of the Carrington Hotel, had given Sorensen his first work in Australia as a gardener. In 1932, he started a garden at "Heaton Lodge", Mudgee, for the Loneragan family, owners of the town's department store; this was the first garden that he created in an area of relatively low rainfall. In 1933, Sorensen met Henri van der Velde, a Belgian-born manufacturer and the owner of Feltex Carpets, who had a vision for a garden at "Everglades", Leura; this garden would become probably Sorensen's best known. During the 1930s, Sorensen worked for seed supplier Anderson & Co in garden design, while keeping his private clients. In 1934, he donated his time, plants and materials to laying out the memorial garden and stone flagging at the War Memorial Hall—now the Country Women's Association Hall—at Leura. Industrialist Cecil Hoskins, who also had a passion for gardens, became a client and lifelong friend. Sorensen designed and planted the garden of Hoskins' newly-built home, "Invergowrie", at Exeter (1936). "Invergowrie" was built on land Hoskins had bought from the estate of Arthur Yates in 1929. In making the new garden, Sorensen was able to make use of some mature trees, hedgerows, beds of daffodils, and orchards planted during Yates' ownership, but photographs taken at the time show the area in front of the house was newly-planted and almost all of the large garden was his work. The association with Cecil Hoskins led to other garden projects, mainly in the Illawarra and Southern Highlands; "Gleniffer Brae", in Wollongong, for Cecil's brother Sidney Hoskins; "Green Hills" and "Hillside" executive housing for Australian Iron & Steel; and the Hoskins Memorial Church at Lithgow. He also created the gardens for "Redlands" at Mittagong. Most of the gardens that Sorensen designed and built were for residences. Noteworthy exceptions were the rooftop garden that he created at Feltex House (an office building) or Henri van der Velde, in 1939, and three garden projects associated with the Hoskins family; the Mount
