Purulia, where the rectangular bungalow is centred in a circle of citrus trees, a conceit which can only be appreciated fully in plan form. Upon this circle Wilson playfully constructs an elaborate network of arcing and radial paths, cross paths and further circles. The geometry is complex but not forced and the architectural detailing is deliberately simple - flagged paths and summer houses with columns of whitewashed tree trunks. Behind the house an apsidal planting of fruiting olives surrounds a sundial on the central axis and screens a semi-annular kitchen and fruit garden. The positioning of the summer house at Purulia, on the cross-axis of the central path and diagonally to the right of the front door, is similar to the positioning of the more sophisticated one at Eryldene. The simple stone-flagged central path is common to all the gardens, yet it is a cottage detail, not found in the old colonial gardens of the County of Cumberland which Wilson knew. Another notable Wilson designed house of this era was Macquarie Cottage, Pymble (1919) for H. Dunstan Vane. In 1920 Wilson & Neave took on John Berry as partner, becoming Wilson, Neave & Berry (1920–27), a firm noted for the Colonial Revival style of architecture for domestic design: fat, low-squatting Georgian boxes with colonnaded verandahs, spider-web fanlights on entrance doors and multi-paned windows with shutters. The firms style followed the Colonial Revival based on the United States idiom, but also looked to Australian colonial architecture for inspiration. This style became very popular in the 1920s. In 1921 Wilson went to China and took lessons in Chinese painting under Kungpah King (Jin Chen); his travels to China's major cities, Peking (Beijing), Hangzhou, Shanghai, Canton (Guangshou) and Macao had a profound influence in his architectural philosophy and design. After Wilson's visit to China in 1921, the firm incorporated Oriental motifs and details, examples of which are found at Eryldene, Gordon (1914–36) and Peapes Department Store, Sydney (1923). In 1922 Wilson sold Purulia and travelled to England and Europe, where, in Vienna, he supervised the collotype reproductions for "Old Colonial architecture in New South Wales and Tasmania" (1924), his publication that would foster great interest in an Australian Colonial Revival. In 1925 Wilson returned to Sydney, where he became disillusioned with the state of Australian architecture and began writing his view sand ideas in a fictionalised biography "The dawn of a new civilisation"
