# 🏠 Draw Your Floorplan - ControlNet

**AI54 Final Project - Spatially Conditioned Floorplan Generation**

## 🎨 Interactive Demo

This Space allows you to **draw colored segmentation masks** and generate architectural floorplans using a fine-tuned ControlNet model.

### How to Use:

1. **Draw** colored regions on the canvas - each color represents a different room type
2. **Describe** your floorplan in the text box
3. **Adjust** settings if needed (inference steps, control strength, seed)
4. Click **Generate Floorplan** to see your AI-generated layout!

### Suggested Colors:
- 🔴 Red - Living room / Main spaces
- 🟢 Green - Bedrooms
- 🔵 Blue - Bathrooms
- 🟡 Yellow - Kitchen
- 🟣 Purple - Dining area
- 🟠 Orange - Office / Study
- 🩵 Cyan - Utility / Storage

## 📊 Model Information

### Training Details:
- **Method:** Full ControlNet Fine-Tuning
- **Base Model:** Stable Diffusion 1.5 (frozen)
- **ControlNet:** Segmentation variant (fully trained)
- **Dataset:** 11,375 orientation-normalized floorplan samples
- **Parameters:** 361M trainable parameters (100% of ControlNet)
- **Training Steps:** 10,000
- **Final Loss:** 0.0887
- **Training Time:** 3.7 hours on T4 GPU

### Architecture:
The model uses a two-stage architecture:
1. **Base Model (SD 1.5):** Generates realistic textures and appearance (frozen weights)
2. **ControlNet:** Guides spatial structure based on colored segmentation input (fully fine-tuned)

This separation allows the model to:
- ✅ Preserve spatial layouts from user drawings
- ✅ Generate realistic architectural details
- ✅ Maintain consistent room boundaries
- ✅ Produce diverse outputs from the same layout
