One of the main problems with housing is it is stuck in place, which gives rise to lots of problems:

1. you have to build round existing structures

2. if the sea level rises, there is nothing you can do

3. small roads can't be widened to accommodate heavier traffic and so on.

In the future the concept of a fixed house would be bizarre, with everything being able to be made portable. It would be normal to have giant shifts in house placement and rewiring of pipes and electricity via AI bots, in order to accommodate change.
