EXPAT - Expandable Shielded Rotating Space Habitat

Growth from initial 8.5m pressure hull radius to 224m radius in 12 radial steps and 4 axial steps. 90 acres of managed woodland over 90 acres of urban outdoor mall space over 5 floors of apartments and commercial space. The mature habitat will feed and support a population of 8,000. Diurnal cycle shared between crop production in the side wall floors and habitable space in the interior. Light switching  reflectors send sunlight up the light shafts to the central reflector enclosing the zero-g industrial workshop.
