Silent dust free reversible assembly of gem-gum-tiles with very high and possibly adjustable thermal isolation can replace concrete, clay bricks, wood, steel sheets, styrofoam and essentially all other materials that today are used in house building. Materials could be delivered via an global microcomponent redistribution system. ("pumping houses")
High level connection mechanisms for AP products should allow taking out bricks of various shapes and sizes. Eiter via makroscale automation or completely manually.
If the materials are in place modifiable they could perform self repair and physical software upgrades possibly using upgrade compatibility microcomponent adapters if the new microcomponents are of different shape than the old ones.
Decor from Nature
For looks thin sheets of stone (e.g. granite) cut out from the lithosphere via advanced underground working can be integrated. The exact location from where it was cut out can be kept stored and the pieces can be protected by thin diamond enclosures. This preserves as much of nature as possible and allows for later research if interest arises at some point in time. The pieces can be made small enough such that they can be easily lugged around by a human one at a time and stacked close enough such that the joint gaps are not visible without a microscope. Pieces of wood bamboo or just about any other nice looking stuff could be encapsulated for wall decor too.
Concrete and clay are among the cheapest materials available today thus AP metamaterials even if as cheap as potatoes might have trouble to compete with them. Inflated low density structures can help making them competitive. Also there's the much higher durability functionality and the possibility to replace at a low rate motivating their usage.
Upgrading old structures
Old concrete structures or asphalt streets could be cut in place into pieces (e.g. cuboids just like outlined in the underground working article) of a size that is nicely handleable by human hands and enclosed in a tough functional diamondoid shell. Those blocks can then be reconfigured by a kind of strength preserving "hole conduction" into a new desired geometry. That is shuffling the bricks around while keeping only a few holes at a time. The blocks could also be shipped of to another place via advanced infinitesimal bearing transport systems of appropriate size.
Reasond for doing this may be
- the building structure is in the way for newer plans
- the concrete is old crumbly or the structure was designed to weak to begin with
- the building structures geometry needs to be analysed
- the carbon in the asphalt is of use
- new cables need to feed through
- Upgraded street infrastructure
- civil engineering
