Background

The pair of houses at 4 and 6 Ada Street are the two remaining of a group of houses built in 1905 by Henry Arthur Goddard using a new method of construction called camerated concrete. Goddard purchased the land in July 1905 and subdivided it into five allotments almost immediately. Two of the houses in this group built by Goddard faced Parramatta Road and have since been demolished.
Camerated concrete was constructed by jump forming concrete with a cavity between the internal and external skin of wall. Henry Goddard patented the system in 1905 as “An improved method of Building in Cnocrete and Apparatus Therefor”, first using it in his Ada Street houses. The system is similar to one patented by Charles May 51 years earlier. Other examples of camerated concrete in the Sydney area were located in Five Dock. The rights for the system was sold in parts of New South Wales, Tasmania and in New Zealand.
