Ma Lin repeatedly saw many people modifying their own houses, adding more complex structures to them.
The federal government enacted laws prohibiting arbitrary modifications, in order to prevent safety hazards or use for criminal activities.
Using space magic to remodel a house can achieve many things.
For instance, the backyard of a house might actually be an alien planet.
Or opening a door might lead one to fall into outer space.
The federal government must manage such incidents.
Although everyone wants to remodel their living spaces as they wish, the aspects involving space magic must comply with regulations.
First of all, if a house internally uses space magic to enlarge or hide a section of space, it must be reported to the building bureau, and the house must have clear signs explaining that the architectural structure involves space magic.
No one is allowed to privately transform their house into a spatial maze.
