This section catalogs a series of design concepts for Aquarius Seed settlements. Owing to the simple nature of foam core ferro-cement platforms used by these structures in sheltered water locations, the Seed settlements of Aquarius will enjoy a much greater freedom in architecture than they will later in their development, when the constraints of an open sea environment and much larger Pneumatically Stabilized Platforms favors the use of heavy masonry construction. But the early stages of settlement also demand very rapid evolution of the community structure as populations grow rapidly and activities and facilities change. This favors building systems which support spontaneous adaptation while still providing a comfortable living environment. However, in the case of Organic design, aesthet
