Under the floor

Soil

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.

In the walls

  • Leaking showers and balconies are the era's defect
  • Dozens of halogen downlights
  • Engineered stone benchtops (safe to live with, not to cut)
  • Estate covenants still in force
  • Site classification (reactive clay) drives slab design and cost
  • Design covenants control fences, colours and even clotheslines
  • Titles and infrastructure delays in newer stages
  • Builder insolvency exposure for anything under construction
What each of these costs to fix

How the streets are changing

Aldinga Beach shacks are being replaced one by one; the estates behind are still releasing.

The thing locals know

Aldinga Scrub and the Washpool are conservation land, so several streets have environmental overlays on top of coastal ones.
