After meritoriously serving with the Royal Horse Artillery in Palestine during the First World War, Hotchkin developed an interest in golf course architecture. Returning to England in 1920, he bought his home course, Woodhall Spa, and set about remodelling it with renowned course architect Cecil K. Hutchison. The original nine-hole Woodhall Spa course had been designed by Harry Vardon, and was subsequently extended to eighteen by Harry Colt. It was Colt's layout that Hotchkin and Hutchison revamped, retaining only one of the great man’s greens.

In the early 1920s Hotchkin published his famous text, The Principles of Golf Architecture. By the late 1920s he had set-up his own golf course design company, Ferigna ... which took its name from his revolutionary iron-based turf dressings and fertilisers.

In 1928 fellow designer Hutchison and family friend Sir Guy Campbell had joined Ferigna. The firm covered all aspects of golf course design, construction, maintenance, equipment, turf dressing and seeding. With its three ex-military officers at the helm, Ferigna undertook the design and construction of several courses in the south of England ... most notably, West Sussex (1931) and Ashridge (1932).
