Construction refers to the assembly of buildings, bridges, habitats, orbitals, megastructures, and so on using nano, meso, micro, and macro-technology. It may also refer to such items that are grown, rather than assembled, with bio, nano, or synano technologies.

- Genie - Text by Anders Sandberg, updated by Steve Bowers
An AI combined with an assembler or other universal constructor, programmed to build anything the owner wishes. A form of Santa Machine. This requires a high level of AI and nanotechnology.
- Gourd Houses - Text by AI Vin
A biotech house grown from a vine-like plant.
- Grazer Wormhole - Text by Adam Getchell
Purpose-built spherically symmetric wormholes carried into systems, such as globular clusters, that are rich in material and energy but (usually) poor in planetary materials.
- Hab / Habitat - Text by M. Alan Kazlev
An artificially constructed environment, whether a dome on the surface of a planet or moon, an orbital or artificial biosphere, a sealed environment in an asteroid belt, a worldship in deep space, or anywhere else, that enables, allows and encourages conditions suitable for sentient life, especially for civilization and sophont beings.

The study and implementation of efficient industrial systems coexisting with the natural environments within which they operate.
- Klemperer rosette - Text by Stephen Inniss
A stable system of heavier and lighter bodies orbiting in a regular repeating pattern around a common barycenter.
- Low World Houses - Text by Wesley Bruce
Low canopies to retain a breathable atmosphere on an otherwise inhospitable planet.
- Mattercache - Text by Todd Drashner
The stores of feedstock matter maintained on a ship or habitat for use as building material, whether for standard operations or emergency repairs.
- Megastructure - Text by M. Alan Kazlev
An exceedingly large construct, typically measuring tens to thousands or even millions of kilometres along its greatest dimension. Megastructures may serve any of several puposes, not all of them mutually exclusive: archailect node, orbital for vec or biont habitation, computronium node for virch or ai life, large ISO, and work of art are some of the possibilities.
- Microbot - Text by M. Alan Kazlev
Autonomous device on the microscale (10-6 m); larger than a nanobot but smaller than a macroscopic bot (the limit is usually set somewhat arbitrarily at one millimeter). Microbots are used for a variety of tasks such as monitoring, repairs, nanite transport and production and smart materials.
- Microgravity Space Habitats - Text by Steve Bowers
Non-rotating habitats with a zero-gee environment
- Morphable Pressurized Tensegrity Cells - Text by John Edds
A technology for producing rigid polymorphic materials and structures that have a low density.
- Nanobot - Text by M. Alan Kazlev; amended by Stephen Inniss and Ryan B
A hylotech, biotech or syntech bot that uses nanoscale mechanisms and manipulates objects on the nanoscale. By convention nanobots are less than one micrometre in size; larger bots enabled by nanotech are referred to as mesobots, cytobots, or microbots, or if they are still larger then they may be called as mitebots, synsects, or simply bots.
- Nanofab/Nanofac Models - Text by Thorbørn Steen
Notable/historic fabricator models
- Nanoseed - Text by M. Alan Kazlev
Nanotech "seed", a self-contained and sealed capsule containing assemblers and replicators either pre-programmed with templates or instructed from an external source. The seed is "planted" on a substrate, and activated with energy or a nutrient spray. It then grows into the desired product, using locally acquired resources and ambient energy (e.g. sunlight) or in the case of some large nanoseeds, a small amat battery.
