openhouse-3d is a free tool that transforms ordinary real-estate listing photos into an interactive 3D model of the house and a cinematic walkthrough video. Imagine taking the pictures from a property listing and getting a virtual tour you can explore room by room—no special equipment, no 3D scanners, just the photos you already have.
Whether you're a realtor, homeowner, or just curious about a property, openhouse-3d does the heavy lifting automatically. It analyzes the photos, figures out where the camera was standing, builds a 3D representation of the space, and then renders a smooth, professional-looking video tour.
- 📷 Photo Camera Solving – Automatically figures out the position and angle of each photo without any manual calibration.
- 🏗️ Procedural 3D Modeling – Builds walls, floors, ceilings, and room layouts directly from the photos using smart algorithms.
- 🛋️ Virtual Staging – Adds realistic furniture, decor, and lighting to empty rooms to make them feel lived-in and inviting.
- 🎬 Cinematic Walkthrough Video – Generates a smooth, camera-animated tour video of the 3D model, perfect for listing websites or social media.
- 🌞 Headless Rendering – Uses Blender's Cycles engine to produce photorealistic images and videos without needing a complex setup.
- 📊 Photo-vs-Render Comparison – Creates side-by-side films showing the original photo and the 3D render, so you can see how accurate the model is.

Once you're on the page, look for the green "Code" button or the "Releases" section on the right side. Click it, and you'll find the download option. The download is a single package that contains everything you need to run openhouse-3d.
After the download finishes, you're ready to move to the next step.
To run openhouse-3d smoothly, your computer should meet these minimum requirements:
- Operating System: Windows 10 or Windows 11 (64-bit)
- Processor: Intel Core i5 or AMD equivalent (or better)
- Memory: 8 GB RAM (16 GB recommended)
- Graphics: Any graphics card that supports OpenGL 3.3 or higher
- Storage: At least 2 GB of free disk space
- Internet: Required for the initial download and for any future updates
If your computer is older or has limited specs, openhouse-3d will still work, but rendering videos may take longer.
- Download the package – Use the download link above and save the file to your computer (e.g., your Downloads folder).
- Extract the files – The downloaded file is a compressed archive. Right-click it and select "Extract All..." then choose a destination folder (like your Desktop or Documents). This will create a new folder named
openhouse-3d. - Run the application – Open the
openhouse-3dfolder you just extracted. Look for a file calledopenhouse-3d.exe(orstart.bat). Double-click it to launch the program. - Follow the setup wizard – The first time you run it, a simple wizard will appear. Click "Next" and accept the default settings. It may ask you to install a small component called "Python" and "Blender" – click "Install" and let it do its thing. This only happens once.
- You're ready! – Once the wizard finishes, the main window will open. You're now ready to create your first 3D house model.
Collect 5–20 photos of the property you want to convert. For best results:
- Take photos from different angles (living room, kitchen, bedrooms, hallway).
- Make sure each photo overlaps slightly with the next one.
- Use a steady hand or a phone tripod if possible.
- Avoid blurry or heavily filtered photos.
- Launch openhouse-3d.
- Click the "Import Photos" button (it looks like a picture icon).
- Select all the photos you want to use (hold Ctrl to select multiple).
- Click "Open" – the photos will appear as thumbnails in the left panel.
- Click the "Generate 3D Model" button (a cube icon).
- The program will analyze each photo, solve camera positions, and create the 3D structure. This can take a few minutes depending on how many photos you have.
- You'll see a progress bar – just wait. When it's done, you'll see a wireframe view of the house.
If you want to add furniture or change the look:
- Click "Virtual Staging" in the top menu.
- Choose from a library of furniture items (sofas, tables, beds, lamps).
- Drag and drop items into the 3D view where you want them.
- Adjust the lighting – you can choose "Daylight," "Warm," or "Cozy" settings.
- Click "Render Walkthrough" (a film clapper icon).
- Choose your video quality:
- Draft (fast, lower resolution – good for preview)
- Standard (balanced)
- High (best quality, takes longer)
- Select where to save the video file.
- Click "Start Rendering." The program will render each frame – this is the most time-consuming step, but you can leave it running in the background.
Once rendering is complete, your video will be saved in the location you chose. You can:
- Upload it to YouTube or Vimeo.
- Embed it on your real-estate listing page.
- Send it directly to clients via email or WhatsApp.
Q: How many photos do I need? A: A minimum of 5 is recommended, but 10–15 gives the best results. More photos mean a more accurate model.
Q: Can I use photos from a phone? A: Yes! Photos taken with any modern smartphone work great. Just make sure they're sharp and well-lit.
Q: How long does rendering take? A: A 1-minute video at standard quality typically takes 10–20 minutes on a mid-range laptop. High quality can take up to an hour.
Q: Do I need any coding skills? A: Absolutely not. openhouse-3d has a simple point-and-click interface. If you can use a photo editor, you can use this.
Q: Can I edit the 3D model afterward? A: Yes. After generating, you can click on individual walls, floors, or objects to resize, move, or delete them.
Q: Is there a trial or is it free? A: openhouse-3d is completely free and open-source. No hidden fees, no watermarks.
Problem: "Python not found" error
- Make sure you ran the setup wizard completely. If not, open the
openhouse-3dfolder and double-clickinstall_dependencies.bat.
Problem: The 3D model looks messy
- This usually happens with too few photos or poor image quality. Try adding more photos, re-taking them with better lighting, or using the "Clean up" button in the Edit menu.
Problem: Video rendering is very slow
- Close other applications to free up memory. You can also switch to "Draft" quality for faster results.
Problem: The application won't start
- Right-click
openhouse-3d.exeand select "Run as administrator." If that doesn't help, disable your antivirus temporarily (then re-enable it after the first launch).
Problem: Missing textures or black screens in video
- Ensure your graphics drivers are up to date. Visit your graphics card manufacturer's website (NVIDIA, AMD, or Intel) and download the latest drivers.
