You conjure a towering mansion up to four stories tall and up to 300 feet on a side. While Casting the Spell, you hold an image of the mansion and its desired appearance in your mind. The mansion can contain as many or as few rooms as you desire, and it's decorated as you imagine it. You can imagine a purpose for each room of the mansion, and the proper accouterments appear within. Any furniture or other mundane fixtures function normally for anyone inside the mansion, but they cease to exist if taken beyond its walls. No fixture created with this spell can create magical effects, but magical devices brought into the mansion function normally.
Your mansion contains the same types and quantities of foodstuffs and servants as created by the Planar Palace spell.
Each of the mansion's exterior doorways and windows are protected by Alarm spells. You choose whether each alarm is audible or mental as you Cast the Spell, and each has a different sound (for an audible alarm) or sensation (for a mental one), allowing you to instantly determine which portal has been used.
Traits
An action with this trait requires a degree of mental concentration and discipline.
You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can't perform actions with this trait. Manipulate actions often trigger reactions.
A spell, item activation, or ability with the structure trait creates a magical building or other structure. The structure must be created on a plot of land free of other structures. The structure adapts to the natural terrain, adopting the structural requirements for being built there. The structure adjusts around small features such as ponds or spires of rock, but it can't be created on water or other nonsolid surfaces. If created on snow, sand dunes, or other soft surfaces with a solid surface underneath, the structure's foundation (if any) reaches the solid ground. If the structure is on a solid but unstable surface, such as a swamp or an area plagued by tremors, roll a each day; on a failure, the structure begins to sink or collapse. The structure doesn't harm creatures within the area when it appears, and it can't be created within a crowd or in a densely populated area. Any creature inadvertently caught inside the structure when it's created ends up unharmed inside the complete structure and always has a clear path of escape. A creature inside the structure when the effect ends isn't harmed, and it lands harmlessly on the ground if it was on an upper level of the structure
