Steven M. Johnson's adresses the problems of the tiny house/ shedworking movement
Over the years many people have tried to address the issues of granny flats, garden office sheds and tiny houses; the ownership model (with rental designs like the OfficePOD) the land use issue (with so many restrictions on size) and the most daunting, the servicing issue.
And in one drawing, Steven M. Johnson solved them all decades ago: The Add-a-Room Corporation will rent you a unit, pretty enough that the City will let you plop it in the front yard and best of all, a big honking standardized service connection for electricity, television, phone, water and sewer. He even designed a little baby carriage to help carry the monster connector.
This idea has (adjustable) legs.
