so, with the demiplane spell i can create an demiplane, an space that exists outside the other planes of existance, the problem is that the space is incredibly small and walled in on all sides with wood or stone or something, however this leaves an weird little question: what happens if i try to break the walls of my demiplane, or try to cast passwall on the walls of the plane? will there just be infinite wood and stone behind the existing wood and stone, letting me tunnel forever and ever and ever, expanding my small space into a much bigger space? does an portal open to the astral sea or the etherial plane, the place between places? or will the passwall spell just fail and the walls prove unbreakable?
I know this is more of an lore question than an game rule question but thins might be useful

There has been a lot of demiplane talk lately and I like it.
I always imagined a demiplane as being like a bubble in the plane where it was created--within it but separated from it. I have no basis for saying this other than it's how I always pictured it. In my example, I guess if you popped the bubble, you'd be right back to where you were before. Perhaps a boring answer.
where can i find this other demiplane talk? i wanna see diffrent oppinions here. Also doesn't the players handbook provide an pretty solid explination as to what an demiplane is?
so basically, the bubble pops, but where exactly would it pop? it has no real-world connection to any location other than maybe the location of the first casting of the spell

There was a module we ran that had a demiplane type structure we walked through that didn't have a roof. If you peered over the sides then it just went into infinite blackness (of which we threw one of the bad guys). So I would say inter planar space that is just an infinite void.
but the cannon interplanar space is called the astral plane, and its like, not empty
Yes .... and no??? They do have stuff, but in places of those transitive planes.
The Ethereal Plane and the Astral Plane are called the Transitive Planes. They are mostly featureless realms that serve primarily as ways to Travel from one plane to another. Spells such asEtherealness and Astral Projection allow characters to enter these planes and traverse them to reach the planes beyond.
The Ethereal Plane is a misty, fog--bound dimension that is sometimes described as a great ocean. Its shores, called the Border Ethereal, overlap the Material Plane and the Inner Planes, so that every location on those planes has a corresponding location on the Ethereal Plane. Certain creatures can see into the Border Ethereal, and the See Invisibilityand True Seeing spell grant that ability. Some magical Effects also extend from the Material Plane into the Border Ethereal, particularly Effects that use force energy such as Forcecage and Wall of Force. The depths of the plane, the Deep Ethereal, are a region of swirling mists and colorful fogs.
The Astral Plane is the realm of thought and dream, where visitors Travel as disembodied souls to reach the planes of the divine and demonic. It is a great, silvery sea, the same Above and Below, with swirling wisps of white and gray streaking among motes of light resembling distant stars. Erratic Whirlpools of color flicker in midair like spinning coins. Occasional bits of solid matter can be found here, but most of the Astral Plane is an endless, open domain.
So depending on where the DM wishes to place your plane or the plane you are in it could have any of those features, or none if it's in the endless open domain portion of the Astral.
Having Demiplane be a bubble that exists within the Astral or Ethereal plane is one possible cosmological view. Another is that demiplanes are seperate and apart from other larger planes in precisely the same way that those other planes are seperate and apart from each other, not nested inside each other like russian dolls. Barovia is essentially a larger but equally spatially-constrained demiplane itself, and players and DMs are comfortable not having an answer to "well what if you tunneled down, what would happen?" Mist would happen, probably, and you'd either be somewhere else, or right back where you started, but in no event would you ever be standing with one foot in each, able to exploit yeeting bad guys into an infinite void :)
like this thread just kinda started as an excuse for me to excavate an larger and larger demiplane until i have something more akin to the demiplanes created by other wizards, becuase honestly infinite rock is just an much easier explanation and leads to the best thing in dnd: creativity

If your DM goes for it, I certainly like it as one way to get started on building a wizard's stronghold! But the rules don't compel that result, after all, the demiplane only "appears to be an empty room 30 feet in each dimension, made of wood or stone," and its true nature could be immutable and otherworldly in a way that confounds normal excavation.

I’m with you on this. What happens if you tip a candle over in a room that is actually wood and you’ve ruled the wooden walls are infinitely thick? Just strange...
I like that it “appears” to be stone, but in reality it’s the end of the plane in that universe. You can’t dig deeper or expand it in any way.
Fill it with Acid 20ft deep and have the door at the top instead of the side. Then leave the door open for people to come in. 🙂

My DM let me get a forked metal rod and attune it to a specific demiplane my char created. It's a Trap Demiplane. So, whenever I need to, I can attempt to Plane Shift a creature there. XD
Haven't filled it with acid (that'll take a lot of acid) - I just put Glyphs of Warding with horrible spells stored. It has 2 traps: first is a 7th level Disintegrate spell. The Second happens is somebody survives the Disintegrate: Sickening Radiance combined with Forcecage (to reduce the option of them teleporting out of the demiplane).
Benefit of Plane Shift: no door to come back out of. :D
I’d like to think of the created demiplane as a “non-Euclidean cube" where the exterior face of any given surface is the interior face of one of the other surfaces, thus if you were to cast passwall you would emerge from the opposite wall or the ceiling, etc. It’s still infinite, just not infinitely big.

My Wizard has a few demiplanes, one of which has beneficial glyphs of warding. If things go really poorly then he has a nice safe room that will cast invulnerability, true poly, foresight, all the investitures, greater invis, greater restoration, heal, etc. Since glyph of warding won't allow you to move the object it's cast on, it just made sense to make the glyphs in a demiplane so they aren't really moving but you can get to them from anywhere.

finally somebody who respects and utilizes the power of having somebody trapped in a room with sickening radiance and no way to get out, will say if you ever get just four more levels you might get wish, letting you cast hallow and thus prevent teleportation and dimensional travel completely
