This module provides a clear and practical introduction to New Zealand Standard 4121:2001 – Design for Access and Mobility, the key technical standard that guides accessible design in the built environment. Participants will explore the purpose, scope, and structure of NZS 4121, understand how it interfaces with the Building Code, and learn how to interpret and apply its requirements in real‑world design and assessment contexts. The module emphasises practical use of the standard to support consistent, accessibility decisions.
