Balustrade heights and window restrictors in Donnybrook

Two safety items measured, not assumed.

Owner Inspections · Donnybrook 3064 · 2026-03-25

In short: Both have been recorded below requirement on Donnybrook jobs, and both carry real risk.

One metre is the minimum

A balustrade below it is a fall risk. We have measured them under on Donnybrook properties.

Window opening restrictors

First floor bedroom windows need a device limiting the opening to 125mm so a child cannot fall through.

Why they get missed

Neither is obvious. Both look finished, and neither is something an owner thinks to measure.

Where else safety shows up

Uncapped reo bar on a slab deck, loose deck boards, deteriorated timber stairs.

How we report them

As safety hazards, separated from quality and cosmetic items.
