Green initially taught mathematics at Cambridge but left to concentrate on furniture design and woodwork and set up business in
Christchurch, Dorset. His work, according to the architect
Hubert Worthington, "combines underlying geometric principles with the traditional practices associated with the work of Ernest Gimson and the Barnsley brothers, but he was also indebted to Georgian prototypes." Romney Green was the author of Woodwork in Principle and Practice in 1918. He used locally sourced timber which he sold direct to the customer, rather than through retailers. Green believed that small scale workshops would help solve the problems of unemployment. During the 1930s he supervised workshops for the unemployed under the auspices of the Rural Industries Bureau, and during the war years, employed invalided ex-soldiers and taught them woodworking skills. He offered apprenticeships, many of whom went on to set up as master craftsmen in their own right. He offered placements to boys who were experiencing educational difficulties which allowed them to learn a trade and increase their self-esteem and literacy skills. Green held essay readings and discussions at his home, which were sometimes attended by
Eric Gill and
Bertrand Russell. Green also lectured at Christchurch Adult School on such topics as the poetry of
William Morris. ==Personal life==
