</p>
**MansionWorld** is a large-scale multi-floor indoor scene dataset for embodied AI research, built on top of the AI2-THOR simulator.
## Key Features
- **1,000 interactive multi-floor buildings** with 2–10 floors each
- **10,000+ rooms** in total across all buildings
- **Diverse building types**: Residential (50%), Office (30%), Public (20%)

## Download
The dataset is provided as zip archives for easier downloading:
| File | Size | Description |
|------|------|-------------|
| `mansionworld.zip` | ~2.9 GB | All 1,000 building scenes |
| `mansion_patch.zip` | ~789 MB | Additional assets (elevators, stairs, etc.) |
## Dataset Structure
After extracting `mansionworld.zip`:
```
mansionworld/
├── {building_type}_{floors}f_{area}_fp{id}#{variant}/
│ ├── floor_1.json # Floor configuration (doors, walls, objects, rooms)
│ ├── floor_1.png # Floor plan visualization
│ ├── floor_2.json
│ ├── floor_2.png

```
### Building Naming Convention
Example: `office_corporate_hq_6f_300_fp001#1`
- `office_corporate_hq`: Building type (office - corporate headquarters)
- `6f`: Number of floors (6 floors)
- `300`: Approximate floor area (m²)
- `fp001`: Floorplan template ID
- `#1`: Variant index
## Usage
Coming soon: Code examples for loading MansionWorld scenes in AI2-THOR.
