It always helps if you design these imaginary worlds with some sense of logic. Form does follow function, and it helps the modeler understand the design intent.

Orem city prison

Southern cities:
Circular shapes dominate in plan. Buildings are raised above swamps and waterways. Sections within the city are connected by a series of bridges.

Northern Cities:
Vertical and monumental styling with influences of art deco and modern architecture, built into steep valley cliff sides. Vast rooftops and landing pads dominate the skyline.

A city located in the narrow valleys and constructed from the debris of scavenged transport ships. These are the oppressed people of this planet.
This production is a good example of artwork "lost in translation". The actual TV series was dreadful.
