- Worth noticing
- The page describes 12-plus seeded cellar and remodel scenarios with teaching notes and “spot the unsafe layout” drills.
Field notes
The described workflow starts with a floor-to-floor height and opening footprint and produces measurements intended to guide stair layout, including a headroom envelope and stringer step-off marks. The page says projects are stored locally and that the launch path uses neither accounts nor cloud services. Its teaching material is framed around cellar and remodel scenarios, with drills that ask users to identify unsafe layouts.
