Our take on some important changes following updates to the NCC 2019
To meet your legislative requirements around external landscaped staircases... All stairs on the access path to the house need to comply with NCC 3.9.1 - Stairway and Ramp Construction.
The updated NCC features this new figure which illustrates the delineated path of access to the building and associated balustrade requirements.
Although the figure above depicts one example of balustrading, all external and landscape staircases are required to comply with Part 3.9 - Safe movement and access - found in Vol 2 of the NCC 2019
For example consider:
Stair riser heights - minimums and maximums
Going widths - consistent
Handrails - where required
Landing specifications - min size and gradient
Slip resistance
