Airlock / Decontamination chamber

A fully functional redstone-operated security airlock designed for survival worlds, laboratories, bunkers, and sci-fi bases. Built in 100% Vanilla Minecraft Bedrock. No mods. No addons. Fully survival compatible.

Overview & Story

In long-term survival worlds, base security becomes part of the atmosphere. This airlock / decontamination chamber was designed as a compact, immersive security checkpoint.

It ensures that one door must close completely before the next can open — preventing accidental breaches and adding realistic movement control between areas.

Whether used as:

• A laboratory decontamination room
• A spaceship airlock
• A high-security bunker entrance

Or simply a dramatic hallway transition

…this build adds tension and realism to your base design.

The system is compact, reliable, and designed specifically for Minecraft Bedrock survival worlds.

Key Features

• Two-stage sliding door system
• One-door-at-a-time safety logic
• Clean redstone layout
• Compact footprint
• Fully hidden circuitry
• Survival-friendly block palette
• No command blocks
• No mods or addons

How It Works

The system uses a simple but reliable redstone logic sequence:

1. Player enters chamber
2. Closes first door
3. Opens second door
4. Exits chamber on the other end
5. Reverse sequence works when exiting

The circuitry prevents both doors from being open simultaneously.

The redstone is compact and fully concealed within the walls and floor, making the chamber look clean and believable in survival builds.

All mechanisms function using:

• Sticky pistons
• Redstone repeaters
• Basic redstone logic
• Pressure plates / buttons

Delivered as an easy-to-import .mcworld file for Minecraft Bedrock Edition.
