I came across this link: http://www.home-designing.com/2009/05/foldable-stairs-industrial-designer. Impressed, I decided to swiftly create a rough version of it using Solidworks. Next, I will consult my carpenter father, who specializes in wooden staircases, about the feasibility of this project. Please leave a "♥" if you like it!
