I do wonder sometimes if standardized, truck haul-able modules of housing wouldn't be an interesting alternative to apartments. Build a building that you plug the modules. Want to move, haul the module to a new building.
I guess I wonder more about what could change to lower the cost of housing.
That's called modular or pre-fab housing and it exists.
The problem here is not building costs, by any means. It's artificial restrictions on the market by local councils who refuse to support higher density living.
I am thinking something a little different than pre-fab, something more along the lines of plug-able module into building. More along the lines of cargo containers in a warehouse.
