Great Interiors is a mission that can be completed at the Utopia HQ and requires the following:
*Some requirements depend on the expansion level.
This mission can be completed more than once and can not be bought out.
Once the mission is completed, the player is awarded a Glass House.
A developer has stated that this mission was not designed to be equitable in value to the other non-astroglass missions. It is a terrible value if you only need the astroglass house for the space. He explained that it exists only so that a completionist who is completely unable to get AG stuff through the Casino will have at least some other method to get this house.
