What "coastal-grade" actually means
- Marine-grade fasteners - 316-grade stainless steel throughout, not just at obvious exposure points.
- Colorbond Ultra roof and cladding in areas within 200m of high-water mark; genuine Ultra spec not just "Colorbond".
- Aluminium window frames with proper drainage or marine-treated hardware.
- Concrete slab designed for reactive coastal sand, appropriate slab class.
- Exterior joinery detailed for salt spray - no exposed steel screws, capped bolt heads, sealed timber ends.
Coastal orientation matters more here than anywhere
Adelaide's coastal breeze is the strongest daily amenity of coastal living, but only if the home is oriented right:
- West/south-west living for afternoon sea breeze.
- North-facing rear yard for winter sun (Adelaide gets bitter southerly wind).
- Master well away from the beach-side prevailing wind so it stays quiet at 2am.
- Alfresco protected from summer 3pm salt-laden gusts.
