General Post Office and the Library and Museum on North Terrace. They supervised erection of German-made prefabricated Palm House in the Botanic Gardens designed by Gustav Runge and opened in 1877. They designed the North Adelaide Primary School. Light is believed to have designed the south-west section of Government House, the Jervois wing of the State Library of South Australia, the Norwood police station. Private No records have been found relating to his work with Hornabrook. Light and Holwell designed St Mark's Church at Woodside. Light and Holwell were architects of the Parkside post and telegraph office, an elaborate complex with an attached hall designed to accommodate 500 people. It is likely he prepared the plans for the replacement St John's church in Halifax Street where Light was the first organist. These plans were presented by Holwell alone to the church committee in December 1884, as were the plans for the tower and other improvements to St George's Church, Gawler.

In 1853 he had a shop on Rundle Street east, "nearly opposite the Exeter Hotel", advertising his services as piano and harmonium repairer and tuner, later having such instruments for sale. By August 1855 he was also advertising his services as a music teacher, and moved his place of business to Franklin Street east.
