We largely use the rules for special manse features as defined in Oadenol's Codex, with the following tweaks:

MAINTENANCE

This drawback is generally allowed, with the understanding that the ST's have full discretion as to whether your character's resources can ensure the maintenance requirements are met.

Manses and Crafting

A Manse which possesses both a Workshop (or Atelier-Manse of Cathedral Factory) and Ability Enlightenment in Lore, Occult and an appropriate Craft provides a +1 (as a Supernatural Aide).  This +1 success doesn't count against the maximum number of Supernatural Aides who can collaborate on an Artifact. A manse without a workshop can still serve as an Aide, but doesn't gain the benefit of not counting against the maximum. 

The Ability Enlightenment feature may be purchased again, as a 5pt Feature (Solar, Air Favored), known as 'Supreme Enlightenment'. Supreme Enlightenment deepens the knowledge and ability of the Manse. It automatically is granted 8 successes on rolls with all of it's Enlightened Abilities, and adds +4 successes (as a Second Circle demon), without counting against the maximum number of such potent assistants.  A Manse without a workshop but with Supreme Enlightenment can still serve as a Second Circle Aide, but counts against the maximum number of such as normal.
