Dr. Falren's Pop-up Practice

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 a large room that has a few doors down either side of it. The atmosphere inside is always warm, comfortable and clean. 

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. Inside contains a doctor's office with all the materials you need to perform more advanced medical practices and places to rest. It possesses the materials you may need for remedy's and minor treatments. A staff of 20 near-transparent servants attend those you choose and act as nurses. You decide the visual appearance of these nurses and their attire. They are completely obedient to your orders and you may also designate another creature within the dwelling that can issue commands to them. Each nurse can perform any task a normal human servant could perform, but they can't attack or take any action that would harm a creature with malice. The nurses can fetch things, clean, mend, fold clothes, light fires, serve food, pour wine, and so on. 10 of these nurses are capable of taking on more advanced commands and concepts that you order them to do, such as assisting in surgery, treatments, or mixing medicines. The nurses can go anywhere in the mansion but 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 inside the extradimensional space are expelled into the open spaces nearest to the entrance.
