The currently documented Build Your Backrooms building list contains Empty Room and Flick Corridor. Both exact names appear in an official Roblox gamepass for Universe 10376944238. This is not a complete catalog. The game description confirms collectible buildings in plural, while public sources do not provide a reliable full index.
Currently documented buildings
Empty Room
Source: included by name in the official “3000 Cash + Smiler + Empty Room + Flick Corridor” product.
Known context: the package description calls it a beginner offer.
Unknown: size, openings, effects, ordinary source, separate cost, and exclusivity.
Flick Corridor
Source: included by name in the same official beginner-bundle product.
Known context: it is a collectible building entity in this exact game's Store data.
Unknown: length, lighting behavior, connectors, effects, ordinary source, and separate cost.
Do not infer room statistics from the order in the bundle name. The product combines cash, a monster, and two buildings, so its total price cannot be assigned to one piece.
What counts as a building entry
An entry needs an exact current name tied to Place 134363641369914 or Universe 10376944238. Good evidence includes an official Roblox product, a readable live collection or shop panel, or a detailed current walkthrough that visibly belongs to the correct game.
Record the source type and check date. Distinguish owned pieces from locked previews and shop offers. When only one independent guide supports a name, label it Community reported. When the name is visible in Roblox or creator-owned material, label that identity Official without promoting unsupported gameplay details.
Do not create a separate article for a name alone. Keep sparse entries in this index until the evidence can help a player identify, obtain or inspect, place, compare, and use the piece.
Useful fields to inspect live
Identity
Exact name, icon or preview, ownership state, source, and current check date.
Route shape
Visible openings, direction, rotation options, and whether each connector is traversable.
Placement
Valid area, collision feedback, cash requirement, and supported move or storage controls.
Visitor use
Whether people reach and traverse the piece on a stable route.
Maze job
Continuation, turn, branch, room destination, monster space, or exploration landmark.
Leave a field blank when the current panel does not support it. A partial, sourced row is safer than a filled card copied from another game.
How to add a building to your own route
Select one endpoint and one owned piece. Read the current cost, enter preview, align openings, rotate using the live device control, and confirm only when placement is valid. Walk the transition from both sides before attaching another building.
Then observe visitors. A piece can be player-traversable while not participating in the route people choose. Keep monsters unchanged during this check. Use Building Placement for errors and Visitor Routes for branch behavior.
Give the building a job. If it does not extend, connect, branch, hold an encounter, or improve exploration, postpone it until the maze needs that role.
Why this is not a value or tier list
No verified public dataset compares all buildings by cost, effect, visitor behavior, or cash. A product inclusion does not establish rarity or strength. A creator’s favorite room may suit a showcase layout but not a starter route.
A future ranking would need the full current catalog, common route tests, live costs, connector data, and explicit comparison criteria. Until then, choose by route fit and use the current preview.
Building list FAQ
Are Empty Room and Flick Corridor paid-only?
Their inclusion in a paid package is official. Exclusivity or another acquisition route is not established; inspect the current game.
Are these the only buildings?
No such claim is made. The official description refers to buildings in plural, and the index is explicitly “currently documented.”
Can community-reported buildings be listed?
Yes, with exact-game evidence, a check date, and a visible confidence label. Unsupported stats remain blank.
Why not copy a Backrooms room list?
General lore and other games do not define the collectible inventory of Build Your Backrooms.
1907209627, plus the official Build Your Backrooms description. Current building walkthrough results support the player intent but not a complete list.
