Paraterraforming involves the construction of large pressurised habitats which contain a breathable atmosphere at a maintained temperature, on a barren and often airless planet. The first steps towards paraterraformation of a world involve the construction of individual domed habitats, but as the population of the world increases these domes become larger and more numerous until they join together into contiguous structures.
Eventually the domes may be replaced by a worldhouse roof, a tough membrane which is largely supported by air pressure but may have any number of supporting pillars where necessary. The membrane can consist of several layers of decreasing pressure to decrease the pressure differential. Most modern forms of worldhouse roof are self-repairing and can cope with small-to-moderate meteor impacts.
Paraterraforming has several advantages over full-scale terraforming. For example the worldhouse starts out as a series of small domed habitats which can be extended gradually when resources are available. The number of size of the habitats can be quite easily tailored to match demand.
In addition, paraterraforming reduces the requirement for atmospheric gases and other volatiles that are needed to create a habitable environment. Using space envelopes of various kinds even asteroids can be given a habitable environment. The environment under an artificial worldhouse roof can also be altered more readily to reflect changing environmental needs or tastes.
Several forms of paraterraforming technology are grown organically using tailored biotech; examples include canopy plants and greenbubbles, and the Yggdrasil bush. Many Dyson trees incorporate habitable compartments within their structure.

Natural and artificial ecospheres left by any of several long-vanished terraformer species known only for the biospheres they left behind long ago. Currently terragenkind is busy terraforming suitable planets in the galaxy, and even if they disappear there are going to be lots of human- and ai- derived biospheres left behind. In a few hundreds of millions of years intelligent life might evolve independently there. This life would find a few other habitable worlds with suspiciously similar biochemistries. - Worldhouses
