What is the minimum height required for a guardrail on a balcony in a high-rise building?

  1. 900 mm

  2. 1000 mm

  3. 1100 mm

  4. 1200 mm

The correct answer is: 1100 mm

Guardrail height requirements vary by location and building codes, but typically a minimum height of 1100 mm is required for a balcony in a high-rise building. Option A (900 mm) may be too low and pose a safety risk, while option B (1000 mm) may be too close to the minimum requirement. Option D (1200 mm) may be too high and not necessary, resulting in unnecessary construction costs.
