Mostly 1980s-90s brick veneer on 400-700m² blocks, sitting on coastal sand, with low pressure to knock down and rebuild. City of Onkaparinga.
Brick veneer with a Colorbond or concrete-tile roof, ensuite, formal lounge nobody uses, double garage under the main roof by the 90s. Rendered feature walls arrive late.
Rendered or face-brick four-two-two, alfresco, theatre room, rainwater tank on the side. Blocks 450-600m². Volume builders on greenfield land.
Two-storey or long single-storey on 300-450m², black window frames, Colorbond Monument roofs, solar on most, 6 or 7-star rated. Very few established trees yet.
Fibro and weatherboard shacks, later brick holiday homes, on sandy blocks near the esplanade. Many now knocked down for two-storey rebuilds.
Good bearing, quick drainage, stable slabs (often Class A or S). The risks are excavation collapse, wind-blown sand under the house, salt corrosion, and the coastal erosion or acid-sulfate overlays that come with living near the water.
Seaford Heights and Meadows stages are the last greenfield. Otherwise established.
The train arrived in 2014 and the suburb has been repricing ever since.

OpenLikely in the older stock. About 10% of Seaford was built between the 1920s and 1980s, the peak asbestos period. Eaves, wet-area sheeting, fences and sheds are the usual places. Test before you drill, sand or demolish.
Coastal sand. Good bearing, quick drainage, stable slabs (often Class A or S). The risks are excavation collapse, wind-blown sand under the house, salt corrosion, and the coastal erosion or acid-sulfate overlays that come with living near the water.
Low subdivision pressure: Streets look much as they did. Occasional renovation, very little demolition. Typical blocks are 400-700m². Check the zone and minimum site area in the Planning and Design Code for the exact street.
Street-level generalisations from council heritage studies, ABS dwelling-age data, soil classification maps and BuildPilot partner site reports. Every street has exceptions. A soil test, a building inspection and the council's overlay map beat any suburb profile, including this one.
