I'm trying to design space habitats and need some estimates on this. Maintaining the lifestyle means that they are capable of produching anything you could get in the West today and are capable of heavy duty engeneering to maintain the habitat. Industries I'm interested in are agriculture (mostly vertical farming and hydroponics), heavy industry (asteroids are the source of ore) and all kinds of general goods production (anything from firearms and clothing to chocolate and nitric acid).
The answer should provide a mass, volume and average density estimate and doesn't have to be highly accurate. I would be quite happy with order of magnitude estimates, but anything more precise would be nice as well. These habitats will be build in the future, so reasonably optimistic estimates are appropriate.
Thanks in advance.
EDIT1: Assume very high levels of automatisation and that blueprints for maschine construction a bought from other habitats in the Dyson Swarm. Industrial Feedstock and energyare imported and are beyond the scope of this question. The habitats aims to be as self sufficient as reasonably possible. Assume no technology not at least in development today, but that this habitat is constructed 500 yeas in the future. The habitat should be able to maintain itself for at least a million years.
EDIT2: This question is only conciderd about the domestic industry of a small habitat. If highly specialised goods are required import is an option.
