Nearly 1500 private and public houses are being built in Seaton, with work now underway on the development's second stage.
Civil works that will unlock the parcel of homes in the extended Seaton project area are nearing completion, as residents prepare to move into the initial 137-home stage next month.
Construction will soon begin on the next lot of homes, which are being built using innovative new materials that offer significant sustainability benefits and the potential to cut delivery time by months.
The two-storey homes are being built using Structural Insulated Panels (SIPs) instead of traditional frames, bricks and plasterboard.
SIPs consist of two durable outer layers bonded to a core of high-density insulating foam, with less air leakage bolstering energy performance for the home. (Pictured is an artist impression of a home to be built in Seaton using SIPs)
The panels are custom manufactured to design specifications, including door and window openings, and delivered to site for assembly on a traditional slab.
Their use streamlines and fast-tracks construction by reducing or completely bypassing framing, bricklaying and internal lining, while factory construction reduces waste through good design and offcut recycling.
The new development stage is bounded by Frederick Rd and Parker, Matthews and Lark avenues, where 27 ageing homes were removed to make way for 66 new dwellings and reserve areas.
Sales began for both vacant land allotments and house and land packages in Stage 2 in mid-2025.
Construction is also progressing on two large apartment complexes earmarked for social and affordable rental housing.
Urban Development Institute of Australia SA Chief Executive Liam Golding said "urgent action at scale" was needed to beat t
he housing crisis.
"Put simply, we need to build more houses faster," Mr Golding said.
"Modern methods of construction can bring down build times and these efficiencies can save time and money - ultimately boosting affordability.
"At Seaton, and across the state, the private sector will continue to partner with Government to get more houses built and get more families into homes."
The Seaton redevelopment - a partnership between Renewal SA and the SA Housing Trust - will see the replacement of 388 dated South Australian Housing Trust homes with a total of 1452 new privately owned and public homes over the life of the project.
