In this section we will explore various design concepts for the unique microgravity housing of the Asgard habitats. We refer to this as Urban Tree housing based on the basic architecture of EvoHab based habitats featuring a large axial core truss with various branches to which the functional elements of the habitat are attached. This tree-like truss structure would provide the primary conduit of traffic and utilities systems within the habitat while buildings and residence structures would be attached on their exterior and accessed through the interstitial spaces in the sides of the truss structure.
