Dryad's tree house

A small tree knot is placed against a tree big enough for a small door 2ft min. Then the door to the tree house springs into existence . The spell ends after  8 hours 

Nine creatures of Medium size or smaller can fit inside the house with you. The spell fails if a tree large enough is not used. Creatures and objects within the tree when you cast this spell can enter it freely. Once the door is close the house is indistinguishable from the normal tree.

Until the spell ends, you can command the interior to become dimly lit or dark. The house contains,  a small table and chairs, a small amount of edible local forest plants, and dimly lit with bio-luminescence fungi on the ceiling. (caution your in a tree)
