Individual Bio-spheres scattered around Earth, typically built under and within mountain ranges for extra protection, were self-contained and self-sustaining cities that could be inhabited for hundreds of years.
Each habitat was built to the same design and specification, with livable space approximately (see note 1) 5 miles in height and diameter. Each was built to contain 14 sections, each of which could be entirely self-contained in an emergency. Each section consisted of 33 floors, each dedicated to a purpose: storage, food cultivation, manufacturing, or living.
Elevators were available on every floor in a section, and the lift system served three of those floors.
Floor types:
Residential Floors were commonly known as ‟Res” or ‟Residence.” Each Section had three Residential Floors. Small shops and kiosks were strewn along the Inner Circle, primarily for sundries, snacks, and drinks. Medical triage, Liaison offices, and community rooms for small gatherings that could be rented ranged along the perimeter that held the Platform Tube and inner elevators.
Each section had one of the following floors:
Culinary Floor: held the Eateries and co-op restaurants. The Culinary floor was laid out in rings, which repeated centerwards and wallwards.
The outermost rings, those closest to the Inner Circle and the Outer Wall, contain the Eateries, each located closest to the elevators.
The next ring holds the counters, serving street food and child-friendly items.
The ring after the counters contain sit-down restaurants offering a wide variety of dishes from many cultures.
The central ring holds co-ops specializing in fine and group dining.
Mercantile Floor: held shopping areas where people could buy from Stores or other co-ops. There were shops for clothing, housewares, furniture, and grooming and bodywork services.
Medical and Research: Medical offices, labs and hospitals shared a floor. Research facilities were scientific or biological, helping move humanity forward.
Academia: Education for all ages, beginning at age six and moving through higher education and more specialized subjects.
Each floor was divided into quadrants, aligned between the compass points with walkways to enable faster movement from the Outer Walls to the Inner Circle. For commonality, each quadrant was further sectioned horizontally into three slices, with the one closest to the inner circle known as the first slice and the other two known as the second and third slices.
Other floors in a section were:
Two floors held generalized Office space.
Two Entertainment Floors: with areas for families, children and adults to meet their differing entertainment requirements.
Four floors, which offered both indoor and outdoor recreational activities.
Agriculture, with one floor of the five farming a specialized food source within the sections; the lake in Section One is an example.
The rest of the 33 floors were divided between habitat systems, industrial and crafting uses, and storage.
Notes:
The habitats were designed according to what was known as Imperial measurements: inches, feet, yards, and miles. In the metric system we know today, a habitat would be considered to have a height and diameter of approximately 8 kilometers each. Each floor held approximately 19.63 miles or 31.5 kilometers of the square area. The total floor space within the cylinder was over 9,000 miles or almost 14,600 kilometers.
