The whole point is for people to commute between

one infrastructure to another without having to wear

radiation suits. (On Mars)

 

And if a colony, there would be many facilities

dedicated to their own cause.

 

If so. Two options.

 

 

Have separate buildings under a glass enclosure,

much like the endangered species preservation structure

but only, massive.

 

This way, buildings are separate,

people can go 'outside' without worries of radiation

within the enclosure, and still see the sky.

 

Oxygen maybe contained in this enclosure.

 

 

Or.

 

Rely on the internal pathways of a one megastruture,

everything connected much like a hive.
