A multi-layered dome settlement is a building, consisting of several shells. Each shell serves a different purpose: The central shell is the best protected part of the settlement, best useful for living rooms. The outermost shell contains store rooms, greenhouses, machinery, etc.

Properties
This settlement can be extended along with a growing population. To build more layers on top makes the inner domes even safer against radiation, meteorites and air decompression. Every additional layer provides an even bigger space.
A cubic building can not grow unlimited, because the inner (old) rooms have to support part of the weight of the outer (new) rooms. In a multi-layered dome building every layer supports itself. Moreover, it is safe against a local failure, because a dome remains stable even if parts of the construction is destroyed.
Material
Brick
Bricks from sintered regolith allow the construction of domes without any further material. Gravity alone stabilizes the building. Neither reinforcement nor grout is necessary.
Specialized bricks can be made for every dome radius and for special shapes. Advantage: The strength of a brick dome can be optimized. Disadvantage: The effort for manufacturing a great variety of bricks is high.
Universal bricks allow different dome radius and shapes with only one sort of brick. Advantage: The manufacturing can be automated easily. Disadvantage: The strength of the masonry depends on the connection between the bricks. It is inevitably weaker than a dome from specialized bricks, for the pressure does not act perpendicular at the surface of each brick in most cases.
Steel
Steel allows the construction of a great variety of dome shapes. Since steel poses great strength even with thin girders, such domes provide optimal space inside. Disadvantages: Steel is probably more expensive to produce than bricks.
Layers
Innermost layer
- Sleeping rooms
- Living rooms
Middle layer
- Working rooms
- Vital machinery
Outermost layer
- Storage of material and inventories
Open issues
- What is better for radiation shielding and protection against meteorites: A brick dome or a steel dome?
