History
In 1924, following his move to the railway town of Peterborough in South Australia’s mid-north, the son of a former partner in the failed Adelaide based Duplex Building Company (refer Parkside Houses), Bert Dennis, launched the Economic Duplex Building Block Company and recommenced the use of the concrete house building method developed by his father. The new Company won a contract to build houses in Peterborough West for the South Australian Railways, and subsequently built further houses to the same design at Tailem Bend and along the Broken Hill to Port Pirie railway, including at Ucolta. Up to 110 houses were built at Peterborough.
According to Dennis’s grandson, cinders from the locomotives was used as the aggregate in the concrete mix.
Examples of the houses can be found on Railway Terrace at Peterborough, Webb Street at Tailem Bend and at Ucolta.
