Staircase Design

The staircase that you design for Experiment One does not need to fit in to building codes, obviously as you are not submitting your design to Council. However I do expect that you have thought about scale and proportion, to suit the purpose of the spaces you are designing.

To assist you with understanding what is considered to be acceptable stair dimension, I have copied some information from the BCA. You do not have to adhere to this, but it would be wise for you to consider, so that you don't come up with completely impractical stairs.

BCA Part 3.9.1.3 - Staircase Construction
- Your staircase must have no less than 2 risers or have no more than 18 risers without a 750mm deep landing or rest area.
- Each tread and riser must be of the same measurement within a single flight
- The riser opening of your staircase if of Open Rise Construction must not allow a 125mm sphere to pass through
