Mostly 1980s-90s brick veneer on 650-900m² blocks, sitting on reactive clay, 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.
Moderately to highly reactive clay (Class M to H). Seasonal movement causes hairline cracking in brickwork and render. Modern slabs are engineered for it; older strip footings were not. Consistent moisture around the house is the whole game.
Very little. Big 1980s homes on big blocks near the reservoir with owners who are not leaving.
The reservoir catchment rules affect what you can do with wastewater and earthworks on the streets nearest the water.

OpenLikely in the older stock. About 25% of Happy Valley 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 650-900m². 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.
