The problem of housing in Stockholm isn't about how expensive it is to build; it is about zoning (and rent control on top of that).
Generally, third-world solutions (tents, shantytowns, container homes, or this) are a solution for how to build cheaply. First-world problems are mostly about zoning and permissions to build.
