Arboreal Abode

You touch a Huge or larger tree and transform it into a magical abode. At the completion of the spell, a magical doorway appears on the surface of the tree in a location of your choosing that leads to an extra-dimensional space within the tree itself. You and any creature you designate when you cast the spell can enter the extradimensional dwelling as long as the portal remains open. You can open or close the portal if you are within 30 feet of it.

You can create any floor plan you like, but the space can’t exceed 10 cubes, each cube being 10 feet on each side. The place is furnished and decorated as you choose, so long as the furnishings aren't made of metal, and the atmosphere inside is slightly humid, yet pleasantly cool. It contains sufficient food to feed 50 people for a single day. A staff of 50 near-transparent fey spirits attend all who enter. These spirits may take the form of any creature with the Fey subtype. They are completely obedient to your orders. Each spirit can perform any task a normal human servant could perform, but they can’t attack, cast spells, or take any action that would directly harm another creature. Thus the spirits can fetch things, clean, mend, fold clothes, light fires, serve food, pour wine, and so on. The spirits can go anywhere in the abode but can’t leave it. Furnishings and other objects created by this spell dissipate into smoke if removed from the abode. When the spell ends, any creatures inside the extradimensional space are expelled into the open spaces nearest to the entrance.
