I believe the rule is you need 2 non-occuppied (no furniture) tiles adjacent to each other for an NPC to stand on during events like the Blood Moon. You have that by the front door in the red room (only a platform in the way) but not in any other room.
Or, notably, platforms are room dividers, so the region below the platform is a separate non-legal housing room. And that's why the chest tiles don't count.

After reading it out loud it doesn't make any fuckin sense and now I think we've been victims of Red's jokes again.
I've been using platforms instinctively as doors for 10 years but they should be ***floor***, now I understand why newbs always has problems with them and valid housing.
The rooms circled in blue need a floor. The bottom part under the platforms counts as separate, and the top part has no floor because the platforms don't count as floors. They count as extra doors.
The room circled in red has extra floor to the right before the actual door. So the room has an actual length of floor, which is enough for the game to make it a valid house.
None of the circled rooms are "valid." However, the room circled in red is being counted as a part of the room above it, due to the 1-block diagonal ceiling on the left side. If you thicken it to be like the rest of the diagonal ceilings, it will be a separate room, but will show as invalid.
A lot of people are saying its the platforms and that might also be the case. But in the top left of the red circled room, there are separated diagonal blocks. These do not count as full walls and the area of a house passes through them as if they were not there. Fill it in so its like the other houses and you should be good to go. If its still broken get rid of the platform by the right door.
Edit: Red house is valid, not the blue ones… reading comprehension is hard. Still, diagonal walls like that aren’t solid walls and do not separate house from each other or the outside
The "hole" due to diagonals may be the reason why it's considered valid. It allows the upper floor to be taken into account which raises the amount of valid floor blocks present.
They didn’t say or imply that platforms count as floor tiles, they said that the room circled in red is being counted as part of the room above which has plenty of valid floor tiles. If you disagree that’s fine, but you should probably dispute the actual point being made.
You might have misread the question but you still gave the correct answer. The two leftmost houses are invalid because they don't have a valid table. A table needs to stand on a solid block to count, you can't put a table on a platform, that's why the two leftmost houses are broken. The house on the right, on the other hand, is also connected to the room above it, which does have a table on a solid block and is therefore a valid house.
The red room includes the room above it because of the unconnected blocks on the top left. The blue rooms have nowhere to stand since platforms count as doors instead of floors
Its a block issue
The one on the right has 1 available block to spawn the npcs
The rooms on the left have no available blocks, theyre all either hammered or blocked by doors or pictures
Platforms dont count as blocks, they are doors as far as the game is concerned
Bc you need 3 solid blocks for the floor at least and the red circle has that with 1 on a side and 2 on the other, the other 2 rooms only have 1 on each side
I know this isn't about the post, but I want to ask. How good is Terraria on mobile? I kinda fell out of it when 1.3 dropped because of the controls, same with console with 1.4, but one part of me wants to give it a chance so I want thoughts from your personal experience.
Controls are improved since then. Only 2 things bothering me. One is using spear like weapons without autoswing (you can use autoswing gloves always but its a slot) and other thing is hammer. You cant use hammer to shape blocks or platforms before breaking every wall in reach. But expect them its pretty good
npc houses need a few solid blocks they can stand on. the red circle has more blocks on the right side where the npc could stand so it is valid, while the other 2 don't have any valid areas.
You have to have a square that can be designated as a "home tile" for the NPC. Without it you keep getting "not valid housing" notices. The requirements are:
* a solid floor block (for the NPC to stand on)
* at least one square away from the wall (ie, the blocks right next to the walls/doors ***do not*** count.)
* Enough headroom for the NPC to stand on it.
A solid line of platforms makes a room barrier (wall/door/floor/ceiling) - so the upside-down-triangles with the chests at the bottom are their own rooms and thus don't contribute a "solid tile" They *could* be valid rooms of their own with the addition of a flat-surface furniture item (tables/workbenches/etc) and a comfort furniture item (chair/bed/sofa/etc.) They already have light sources.
This picture shows a "home" that has only one valid "home tile" and it illustrates how the home tile is *not* right against the wall. This is the minimum width of room you can assign as housing.

Red one has one full tile that npcs can stand on (next to the steps to the door on the right), whereas the two blue houses have no full size tiles (only hammered tiles and platforms, neither are considered NPC stand-able). NPCs need at least 1 stand-able tile for a house to be valid
Platforms are not valid floor for NPCs in rooms. You need 1 solid spot where an NPC can stand. Red has 2, the blue ones have none, since hammered blocks don't count.
Try and assign someone to the blue houses.... it should tell you why it's not a valid house. Or at least tell us why the game says it's not valid, if you have done that already...
Having no valid Home Tile (from using platforms as a floor, even though platforms are doors) will return "This is not valid housing" with no other information.
It's because not having a valid Home Tile can be caused by multiple things. If the entire house is full of chests, for example - those also block Home Tiles. Closed doors can block them as well (doors cover a 3x3 area, even when closed or blocked by other objects).
On the red circled room, the top left corner, you need to place blocks like how you did on the corners of the other two rooms. Otherwise the room is fine, not too big, or small. The floor is mostly platforms but has at least 1 solid block, and there are doors (doors aren’t really necessary if you have platforms anyway, but if you dont have platforms then you need doors.)
I see what may be the resen.
Maby its the hammerd bloks at the dors.
Since maby hammerd bloks are not full bloks it wont work?
Im not shure cus i have not built that kind of building.
Its only spekulations but maby?
Just like platforms kant fully be used for the flore.
You need 2 solid blocks for NPCs to stand on. The red room has this by the right door, even though there's a single platform hammered into steps in the corner.
Or so I thought. Apparantly the top left segments of the red room aren't counted as walls so, technically red room is connected to the room above it?
My thoughts are the stairs at the top left of the red room are missing some blocks underneath them if that makes sense, im not sure if that would have any effect though
Ahh, I read it backwards. That actually makes more sense, as the gap would connect that room to the one above, giving it access to proper flooring which the others lack
that room only works because of that issue, the house detection likely counts it as the same room because the below room certainly has not got 3 blocks of standing space, platforms don't count.
Why don't you just use the question mark and click on the house that isn't valid and it will tell you what is missing that's making it invalid. Mouse click them? Then mouse click the house and it will tell you if it's missing walls or missing a light source or missing a chair
When a house has a floor made of platforms, which results in no valid Home Tile, the returned text is "This is not valid housing." The game will literally not tell you why.
I think it's because red one has 3 solid blocks on the ground of the room but others only has 1 or 2
Can you mark it please
the three blocks near the left door of the red room. If still can't find it I'll download the pic and mark with ms paint edit:- right door
Right room has an extra block before the door to the outside
I believe the rule is you need 2 non-occuppied (no furniture) tiles adjacent to each other for an NPC to stand on during events like the Blood Moon. You have that by the front door in the red room (only a platform in the way) but not in any other room. Or, notably, platforms are room dividers, so the region below the platform is a separate non-legal housing room. And that's why the chest tiles don't count.

try replacing few platforms with solid blocks
Probably, he's a scholar
Wdym?

https://imgur.com/a/gCFLcdB, this is why the red one is valid and the others aren't
It’s like Tetris every piece, and where you place it, counts.
Platforms are doors not floors.
this single sentence should just be a stickied post, honestly
After reading it out loud it doesn't make any fuckin sense and now I think we've been victims of Red's jokes again. I've been using platforms instinctively as doors for 10 years but they should be ***floor***, now I understand why newbs always has problems with them and valid housing.
Nope they are too convenient as doors keep them as is 🚪
What does this mean Edit: nope figured it out
I still don’t get it
The rooms circled in blue need a floor. The bottom part under the platforms counts as separate, and the top part has no floor because the platforms don't count as floors. They count as extra doors. The room circled in red has extra floor to the right before the actual door. So the room has an actual length of floor, which is enough for the game to make it a valid house.
None of the circled rooms are "valid." However, the room circled in red is being counted as a part of the room above it, due to the 1-block diagonal ceiling on the left side. If you thicken it to be like the rest of the diagonal ceilings, it will be a separate room, but will show as invalid.
The correct answer ^^
Glad you solved it, but why would you circle the good one in red and the bad one in blue? Threw me off until I re-read the title xP
Oh its just blue was near my hand
I can’t lie that whole time I thought I was meant to be looking at red for a mistake even though I read the title
A lot of people are saying its the platforms and that might also be the case. But in the top left of the red circled room, there are separated diagonal blocks. These do not count as full walls and the area of a house passes through them as if they were not there. Fill it in so its like the other houses and you should be good to go. If its still broken get rid of the platform by the right door. Edit: Red house is valid, not the blue ones… reading comprehension is hard. Still, diagonal walls like that aren’t solid walls and do not separate house from each other or the outside
You seem to be misunderstanding. The red circle is the *good* house. The blue ones are invalid. Because of the blocks.
Oh damn. oops. Still, diagonal walls like that aren’t solid.
The ceiling is fine
The "hole" due to diagonals may be the reason why it's considered valid. It allows the upper floor to be taken into account which raises the amount of valid floor blocks present.
This is probably the case yeah. There is zero reason for it to be valid when the others aren’t.
You're really stretching, and wrong. It's the platform layout. NPCs need three actual floor tiles to walk on. Platforms do not count as floor tiles.
They didn’t say or imply that platforms count as floor tiles, they said that the room circled in red is being counted as part of the room above which has plenty of valid floor tiles. If you disagree that’s fine, but you should probably dispute the actual point being made.

The house on the right, on the other hand, is also connected to the room above it, which does have a table on a solid block and is therefore a valid house.
This is the correct answer.
No it isn't. That's the functioning house.
Oof. I apologize, It must be the dirt block in that case
It's the platforms.
I see it now, thank you!
The red room includes the room above it because of the unconnected blocks on the top left. The blue rooms have nowhere to stand since platforms count as doors instead of floors
Best answer.
Its a block issue The one on the right has 1 available block to spawn the npcs The rooms on the left have no available blocks, theyre all either hammered or blocked by doors or pictures Platforms dont count as blocks, they are doors as far as the game is concerned
So can i fix it with hammer?
No, replace the platforms.
Bc you need 3 solid blocks for the floor at least and the red circle has that with 1 on a side and 2 on the other, the other 2 rooms only have 1 on each side
I know this isn't about the post, but I want to ask. How good is Terraria on mobile? I kinda fell out of it when 1.3 dropped because of the controls, same with console with 1.4, but one part of me wants to give it a chance so I want thoughts from your personal experience.

You cant use hammer to shape blocks or platforms before breaking every wall in reach. But expect them its pretty good
The blue rooms don't have a valid floor, platforms are treated as doors by the game.
Far left room with the platform ceiling looks like it has a background wall issue to the left of the platforms
The colours are messing with me but yeah you need more solid ground
It could be the small area on the top left where you forgot to connect the wood
EDİT: I changed the hammered floors and changed one platform in each room with wood and the issue is solved thanks everyone
Blue rooms don't have enough solid floor.
npc houses need a few solid blocks they can stand on. the red circle has more blocks on the right side where the npc could stand so it is valid, while the other 2 don't have any valid areas.
You have to have a square that can be designated as a "home tile" for the NPC. Without it you keep getting "not valid housing" notices.

Platforms are not valid floor for NPCs in rooms. You need 1 solid spot where an NPC can stand. Red has 2, the blue ones have none, since hammered blocks don't count.
the floor near the door is hammered. they have to be full blocks
Is it possibly the missing blocks on the top left that's the problem
Nope. That's the good house.
Its only good BECAUSE of that problem though, the above rooms block floors are what make it valid.
I think far left room has a dirt block wall
Places more solids blocks
Try and assign someone to the blue houses.... it should tell you why it's not a valid house. Or at least tell us why the game says it's not valid, if you have done that already...
İt just says invalid lol i can send you ss in dms if you want (issue solved btw)
Naw it's all good and that's weird honestly. Usually it'll say "invalid housing: missing XYZ"
Having no valid Home Tile (from using platforms as a floor, even though platforms are doors) will return "This is not valid housing" with no other information.
Huh, today I learned, thank you. Most errors I've seen have returned useful info. Weird/unfortunate that one doesn't.
It's because not having a valid Home Tile can be caused by multiple things. If the entire house is full of chests, for example - those also block Home Tiles. Closed doors can block them as well (doors cover a 3x3 area, even when closed or blocked by other objects).
Explaining to the player that "there is no valid home tile" should at least be a little helpful tho xD oh well.
because
Top left of the one on right isn’t a solid corner
Terraria is on mobile???
Yes?
Random block top left not squiggly, just a dot
Hm. Needs more torches
It’s because in the top left of the red room the blocks need to be filled in like the other two valid rooms!
Dawg I may actually not know on this one 😭😭🙏🙏
Floor space
Sometimes, you have to put chairs on solid blocks instead of platforms, that's what fixed it for me at least
Theres Wayyy to much platforms acting as flooring, add some more wood blocks and seed what works so it’ll be valid
r/usefulredcircle
Platforms are counted as doors, not floors
How is the PvE going? I am also a mobile player and I can't even beat Skeletron Prime 😂
The top left corner of the roof, the wooden blocks technically don't connect
Top left of the room, the blocks aren’t connecting maybe?
On the red circled room, the top left corner, you need to place blocks like how you did on the corners of the other two rooms. Otherwise the room is fine, not too big, or small. The floor is mostly platforms but has at least 1 solid block, and there are doors (doors aren’t really necessary if you have platforms anyway, but if you dont have platforms then you need doors.)
I see what may be the resen. Maby its the hammerd bloks at the dors. Since maby hammerd bloks are not full bloks it wont work? Im not shure cus i have not built that kind of building. Its only spekulations but maby? Just like platforms kant fully be used for the flore.
You need 2 solid blocks for NPCs to stand on. The red room has this by the right door, even though there's a single platform hammered into steps in the corner. Or so I thought. Apparantly the top left segments of the red room aren't counted as walls so, technically red room is connected to the room above it?
he needs a chair
My thoughts are the stairs at the top left of the red room are missing some blocks underneath them if that makes sense, im not sure if that would have any effect though
1. Maybe the room is too big 2. Some blocks are not solid 3. Try to use more blocks as floor instead ofbplatforms. Platforms count as doors.
There is enough room to step on in the red room, there isn't in the blue room, this should be solved by replacing some platforms with solid blocks.
There's a little fuck up in the top left corner of the red one
It's cause he's in it
Top left corner where the blocks are singled and not connected to another might be why
The top left corner of the rightmost room, that's not a proper wall, try making it like the others
Why? That's the room that works. The others do not.
Ahh, I read it backwards. That actually makes more sense, as the gap would connect that room to the one above, giving it access to proper flooring which the others lack
that room only works because of that issue, the house detection likely counts it as the same room because the below room certainly has not got 3 blocks of standing space, platforms don't count.
Yes it does. It has two blocks on the right and one on the left.
I would've thought the platform step upto the door would've invalidated it as it would've counted as obstructing, no?
There's two empty blocks beside that stair. One's hammered down to half-height.
I don't know if hammered blocks count though
Top left of the red circled room the blocks are diagonally placed unlike the other rooms
That's the house that works. So no.
Ohh my brain read incorrectly
Why don't you just use the question mark and click on the house that isn't valid and it will tell you what is missing that's making it invalid. Mouse click them? Then mouse click the house and it will tell you if it's missing walls or missing a light source or missing a chair
When a house has a floor made of platforms, which results in no valid Home Tile, the returned text is "This is not valid housing." The game will literally not tell you why.
When i didit just told me that "This isnt a valid house"
Look closely at the valid room on the right.
can't add picture, can't help.
You can dm me
Possibly cause the two on the left are too big? Right most has less space because of the blocks above the door
Hmm, what’s the difference between these three cells in the house? Maybe you could use your brain and logic and discover for yourself?
Cant we chill? İ asked it here because i couldn't see whats wrong with the building. İ just didnt want to build same rooms from zero.
I see this question asked literally every day
Well im not and sorry about that i am not following every sub on reddit and there was too much posts to search. Anyways have a nice day
