See Soulcrafting Tutorials and Soulcrafting for the basics.

Design
The design of a soulhome needs to take into account size, cantae flow, purpose, and suitability of a sublime material. Changes can be made to materials, floors, soul and the soulcrafter during ascension.

A well designed soulhome has many interconnected features that support each other and wastes minimal time on things that will have to be changed later. Each stage needs to be able to resist every ascension going forward.

Size
All soul crafters have roughly the same size of soul, it only expands from the initial opening of the soul (tier 1) at Archcrafter (tier 2). This means rooms must be designed with care to avoid wasting the limited space. The larger a room in the soul the more cantae and sublime materials it can hold. Many soul crafters do not have enough materials to fill their soulhomes and only build small soulhomes. Each additional tier provides an additional floor. With some exceptions, each additional floor cannot be larger than the floor beneath it. Not building a soulhome large enough is one way to become stuck at lower tiers.

A room may be dedicated to a single purpose (typically small rooms), multiple related purposes (mid sized), or be a multipurpose room (large). All can be powerful if well designed.

Theo's soulhome is many single purpose rooms while Nauda's is fewer rooms with multiple uses. This gives Theo a limited number of focused, fast and, powerful techniques but requires him to link his rooms to each other on each floor as well as across tiers to create more complicated effects. This means at the start Theo is rather limited. Nauda is more flexible and overall more powerful from the start but her design falters at later stages.

Cantae flow
Some sublime materials produce large amounts of cantae. Cantae flows from materials through openings in the soulhome. The heart chamber typically produces most of the cantae the soulcrafter uses. Openings are typically open spaces such as doorways or conduits. Excess opening waste cantae. Is a soulhome design can channel cantae though multiple related rooms it will produce more powerful effects. Windows allow for changes to the cantae as it flows or to release a technique without the waste of cantae an opening in the outside wall of a soul home would cause.

Suitable Materials
The sublime materials used must fit the soul, the plan, and the purpose it is set to. Sublime materials have innate properties such as light, floating, or fire.
