Sylwrae's Tower

You conjure a sturdy three-story tower made of stone, wood, or similarly durable materials in an unoccupied space on the ground that can accommodate its 25-foot-radius size. If there is insufficient room for the tower to appear, the spell fails.

The tower's interior is arranged according to the caster's wishes at the time of casting.
You determine the placement and layout of its rooms, hallways, staircases, doors, windows, and furnishings. The tower may contain any number of practical living spaces, including bedrooms, lounges, studies, kitchens, dining rooms, washrooms, storage rooms, or other similar chambers.
The tower is furnished with mundane fixtures and household goods appropriate to its intended purpose, including beds, tables, chairs, shelves, rugs, fireplaces, cookware, tableware, bathing facilities, lighting, and other ordinary furnishings. These objects are nonmagical but are created by the spell and disappear when the spell ends. Any furnishing or object created by this spell dissipates into smoke if removed from the tower.

The spell cannot create personal possessions, valuable objects, consumable supplies, books containing written knowledge you have not read, food, drink, tools, weapons, armor, spell components, or any other item with intrinsic value or specialized function. Such items must be brought into the tower normally. 

The interior of the tower is warm, dry, and comfortably furnished regardless of the conditions outside.
At the end of the spell's duration, all creatures and objects within the tower that were not created by this spell appear safely outside on the ground, and all traces of the manor and its furnishings disappear. You can dismiss the tower early as a magic action, but only if no creatures remain within it.

You can cast this spell again while it is active to maintain the tower's existence for another 24 hours. You can create a permanent tower by casting this spell in the same location and with the same configuration every day for one year.
