Artificer’s Slightly Less Magnificent Mansion

You build a stone doorway that is 5 feet wide and 10 feet tall with magical runes carved into it, you then make a wooden door with a silver door knob that fits in the doorway. when you open the door you conjure a portal to an extradimensional dwelling in the doorway. 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 use the door to open or close the portal.

Beyond the portal is a foyer with numerous chambers beyond. The atmosphere is clean, fresh, and warm.

You can create any floor plan you like, but the space can’t exceed 25 cubes, each cube being 10 feet on each side. The place is furnished and decorated as you choose. It contains sufficient food to serve a three-course meal for up to 15 people. A mechanical servant attends all who enter. You decide the visual appearance of this servant and it’s attire. It is completely obedient to your orders. The servant can perform any task a normal human servant could perform, but it 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 mansion but it can’t leave it. Furnishings and other objects created by this spell dissipate into smoke if removed from the mansion. When the spell ends, any creatures or objects left inside the extradimensional space are expelled into the open spaces nearest to the entrance.
