Ground, access and local conditions

Steep sandstone slopes to Middle Harbour and Balmoral Beach; salt exposure on the harbour-facing streets.

Salt air means aluminium over steel for open front fencing and pool fencing; Colorbond boundary fences are specified with the right fixings.
Sloping blocks call for stepped Colorbond or retaining walls; access via steps is common and allowed for in the price.
Slat and louvre privacy screens are popular where neighbours overlook from above.
