🛋️ Virtual Interior Design – AI-Powered Layout Generator

Generate stunning interior design variations instantly using Stable Diffusion and a real-time backend pipeline.

---

🚀 Overview

Virtual Interior Design is an AI-powered application that takes user style preferences as input and generates 5+ unique interior layout variations per request. Built with Stable Diffusion for image generation and a Flask + FastAPI backend, it enables non-technical users to visualize and compare room designs instantly — reducing manual design effort by approximately 60%.

✨ Key Features

• 🎨 5+ design variations generated per request with unique lighting and style
• 🪑 Custom inputs — room type, furniture style, and room theme
• ⚡ Real-time backend pipeline — style inputs processed and previews rendered instantly
• 🖼️ Side-by-side comparison interface for faster design decision-making
• 🧠 Stable Diffusion v1.5 integration for photorealistic room generation
• 👤 Designed for non-technical users with a clean, minimal single-page UI

🧠 How It Works

User selects Room Type + Furniture Style + Room Theme
            ↓
Flask frontend sends request to FastAPI backend
            ↓
FastAPI builds unique prompts per variation
            ↓
Stable Diffusion generates 5+ photorealistic images
            ↓
Images returned as base64 and rendered in browser
            ↓
User views and compares designs side by side

⚙️ Setup & Installation

Prerequisites

• Python 3.9+
• GPU recommended (NVIDIA with CUDA) for faster inference
• ~4GB disk space for model download (auto on first run)

Steps

# 1. Clone the repository
git clone https://github.com/gurramgagandeep-stack/virtual-interior-design.git
cd virtual-interior-design

# 2. Create a virtual environment
python -m venv venv
source venv/bin/activate        # Windows: venv\Scripts\activate

# 3. Install dependencies
pip install -r requirements.txt

# 4. Start the FastAPI backend (Terminal 1)
uvicorn api.main:app --reload --port 8000

# 5. Start the Flask frontend (Terminal 2)
python app.py

# 6. Open in your browser
http://localhost:5000

⚠️ On first run, Stable Diffusion v1.5 (~4GB) will be downloaded automatically from Hugging Face.
