The cistern is not only for water storage. It is a means of flood control. There may come a time when it is mandated by legislation. Drought will be relieved by terrible storms that dump a lot of water in a short period of time. In large, relatively flat municipalities the cistern will be a major defense against urban flooding without straining already stretched budgets. Tax breaks, codes and incentives will have many urbanites installing, at the least, several rain barrel cisterns connected to their gutters to take the load off storm drains.
Because water has the ability to store a lot of heat, the cistern will also act as a thermal heat sink to control the temperature of your future house. It will be like a combination of a geothermal installation and what is called "mini-splits" air conditioners. A heat exchanger/fan built into the wall, ceiling, or floor will be connected to the cistern with a copper tube loop and a small pump. The difference from geothermal is that the cistern will have active elements enhancing the temperature of the water. It may even involve two insulated cisterns, one for hot water and one for cold. A smart thermostat will determine the required combination of hot and cold water to keep you comfy. The solar heating coils and evaporative cooling coils work off of small solar-powered pumps making it much more cost effective than today's central air and heat.

The D-Shape printer infuses layers of sand with a special inorganic binder to print out almost any design you can come up with. The resultant material is similar to marble; very strong, needing no steel reinforcement. Although not the maximum size D-Shape can print, the sculpture Radiolaria captures the freedom one would have in designing their own home. Radiolaria is 3 meters x 3 meters x 3 meters. The current version of D-Shape can prints things twice that size.
I visualize discrete pieces printed to maximum practical shipping dimensions that are joined together at the erection site to form incredible new architectural and sculptural expressions of any size. An integral water catchment tank can be printed into the roof. In the summer, thermostatically controlled weep-holes open to let it trickle down, spreading out through the maze-like textural wall pattern. The resulting evaporative effect will keep the whole house naturally cool. D-Shape will print heating/cooling coils integral to the walls. Your house would be very strong and resistant to storm damage. It's not a big step to imagine D-Shape being fed other material besides sand to create different R-values, densities, translucency, etc.

These are near-term trends (say, the next 50 years) for shelter. If scientists are correct, we could be in for some scary stuff long-term. If the climate has gone completely to hell, it may become cheaper to build on a grand scale to cut down on the costs of heating, cooling and transportation.
The X-Seed 4000 is over 13,000 feet tall and houses 1,000,000 people. Although this iteration appears to be located somewhere in the Middle East, it was originally designed to sit in Tokyo Bay. Parks and Recreation on floors 300, 600, 900 and 1000. You have to admit it does cut down on commuting costs and does away with grid losses on generated electricity. And it's very possible there could arise a new working-class hero--the window washer.
