And note that due to geometry of stairs and landings, floor area consumed increases at a greater-than-linear rate relative to width. See drawings from Conrad (notice his narrowest stair is wider than the typical US requirement). 1.5m stair consumes almost the same area as two 1.1m scissor stairs!

We're excited to be on Bluesky after many years on Twitter. Check out our latest blog post for details on changes to California's state ADU law that will allow up to 8 new detached homes per parcel: openscopestudio.com/sb-1211-deta...
