I’ve seen people run actual companies and they needed a ton of space to keep legal documents, spec books, and a professional grade printer to copy binders of docs. They were fully utilizing the room.
But I doubt most people run companies, and personal docs usualy fit in a single box. Most people also use laptops, consumer printer/scanners are pretty unobtrusive, if people even keep one.
All of that would fit in half of a cabinet, so what I am missing that goes into an office room ?
