Mostly 1980s-90s brick veneer on 700-1,000m² blocks, sitting on hills soils on slope, 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.
Brown brick veneer, mission-brown aluminium windows, ducted evaporative on the roof, a family room off the kitchen and a pergola out the back. Project homes from the big volume builders.
Rendered or face-brick four-two-two, alfresco, theatre room, rainwater tank on the side. Blocks 450-600m². Volume builders on greenfield land.
Two or three homes where one 1960s house stood: Torrens-title courtyard homes, hammerhead battle-axe blocks, occasional two-storey townhouse rows.
Shallow clay loam over rock, often steep. Movement is less about reactivity and more about slope stability, stormwater and cut-and-fill. Retaining walls become the biggest hidden cost, and bushfire rules shape the whole design.
Renovation only. Steep blocks and the golf course make subdivision rare.
Split-levels and pole homes on the slopes above Craigburn Farm; retaining walls are the local repair industry.

OpenLikely in the older stock. About 35% of Flagstaff Hill 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.

Low subdivision pressure: Streets look much as they did. Occasional renovation, very little demolition. Typical blocks are 700-1,000m². 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.
