Shape & Size

Pick a deck shape and size. Use “Along house wall” for the dimension that runs across the house, and “Out from house” for how far the deck extends. The subframe rebuilds automatically.

4.0 m
How wide the deck runs across the house frontage (parallel to the wall).
3.0 m
How far the deck extends out from the house wall (perpendicular).
0.6 m
0.00 m
Use this when the ground falls away from the house. Lengthens far-edge posts.

Your subframe is engineered for you. Footings, posts, bearers and joists are all sized to AS 1684 from your deck's size and height, nothing to set here.
