Beauregard’s Cozy Cabin

You conjure an extradimensional dwelling in range that lasts for the duration. You choose where its one entrance is located. The entrance shimmers faintly and is 5 feet wide and 10 feet tall. 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. While closed, the portal is invisible.

Beyond the portal is cozy wooden cabin with a magical projection of winter mountains outside the windows, though all attempts to leave the cabin besides the use of the main door fail. The atmosphere is fresh, clean, and comfortable.

You can create any floor plan you like using the available space, but the size can't exceed 25 cubes, each cube being 10 feet on each side. The place is furnished and decorated in any way you like, but these and other objects created by this spell dissipate into confetti if removed from the cabin. It contains enough food to serve a 3 course home-cooked meal for up to 20 people, A single near-transparent servant attends all who enter. You decide the visual appearance of this servant and their attire. They are completely obedient to your orders. This servant can perform any task a normal human servant could perform, but they can't attack or take any action that would directly harm another creature. Thus the servant can fetch things, clean, mend, fold clothes, light fires, serve food, pour wine, and so on. The servant can go anywhere in the cabin but can't leave it.  When the spell ends, any creatures inside the extradimensional space are expelled into the open spaces nearest to the entrance.
