How AI transforms a simple floor plan into a digital property twin
Floor plans have been a core part of real estate listings for decades. But they come with a problem: many people struggle to interpret them. With our new feature Paper2Pixel, users of Realitiq can upload a floor plan – whether as a PDF or a photo – and instantly convert it into a digital twin. Using AI, the system automatically detects walls, windows, and doors to generate a precise digital model of the property.
2D & bad quality
The challenge with traditional floor plans
Floor plans are standard practice for real estate agents. However, for many prospective buyers, they are anything but intuitive. Lines, symbols, and measurements require spatial reasoning skills—something not everyone possesses. Furthermore, not every available floor plan for a property is of optimal quality: traces of multiple copies, poor scans, creases due to size—what you receive from sellers, building authorities, and the like is usually less than ideal.
This often leads to important information being lost. Potential buyers don’t fully understand the layout or quickly lose interest because they can’t properly visualize the property.
This is precisely where Paper2Pixel comes in.
Our AI-Transformation
From paper to pixel – automatically
With Paper2Pixel, users can easily upload an existing floor plan – whether as a PDF document or a photo of a printed plan. The AI analyzes the floor plan and automatically recognizes the building’s structure. This works just as well with hand-drawn and low-quality floor plans as it does with high-resolution plans.
The system identifies:
- Walls and room structure
- Windows
- Doors
From this information, a digital twin of the property is automatically created.
Scale model
Scaling the model with a single measurement
To ensure the model is accurately scaled, the system only needs one reference measurement from the floor plan.
Users simply select a known distance on the plan using a digital ruler in the interface and enter the corresponding real-world measurement. The AI applies this reference to the entire layout and generates a correctly scaled model.
The entire process takes only a few seconds.
The digital Twin
Foundation for modern real estate marketing
Once a floor plan has been converted into a digital twin, a wide range of new possibilities opens up.
The model can be used for:
- virtual property tours
- flexible interior visualizations
- AI-generated renderings from different perspectives
- interactive digital exposés
Instead of a static floor plan, the property becomes a dynamic and immersive experience.
Learn with practise
AI already detects walls, doors, and windows
The current version of Paper2Pixel automatically recognizes key architectural elements in floor plans, including walls, windows, and doors. This allows the AI to interpret the basic structures of properties with high precision and translate them into digital models.
Development is still in its early stages. Occasionally, manual correction of individual walls is still necessary. However, the more Paper2Pixel is used by our users, the better the AI’s recognition capabilities will become. Currently, it achieves an 80% accuracy rate across all quality levels.
Future versions will allow the AI to recognize furniture already drawn in the floor plan. This will enable even faster conversion of existing floor plans and new forms of automated room visualization. Furniture already included in the floor plan can then be directly transferred to the digital model.
AI makes it faster
Why Paper2Pixel is a major efficiency booster
Creating a digital real estate model has often been a complex and time-consuming process: manual modeling, specialized software, or external service providers. Our process was also largely manual, involving the manual redrawing of existing floor plans. While it’s still possible to quickly create a digital twin using a LiDAR scan of the actual property, this requires you to be physically present at the property first.
With Paper2Pixel, we offer a location-independent process that leads to a digital twin in just a few steps:
- Upload the floor plan
- Define reference measurement
- Generate the digital twin
This saves time and money and makes modern real estate visualization significantly more accessible. Furthermore, the generated digital twins can be easily modified and improved at any time using our editor. This allows you to change floor and wall textures and add furnishings.

Sales plans of perfect quality
Our AI-powered conversion of floor plans into digital twins also includes a high-quality sales plan. This can be used in place of the original plan for brochures and advertisements, offering significantly improved quality. You can be confident that our sales plans are guaranteed to be free of copy marks or scanned paper creases. Furthermore, our floor plans only show the (residential) unit being marketed, whereas architectural plans often depict the entire floor, with each unit typically marked by hand with a highlighter.
Creating experiences
From static documents to digital properties
The real estate industry still relies heavily on traditional documents: PDFs, plans, and static images. Paper2Pixel helps transform this content into digital, interactive models. This digital twin allows for easy switching between different views (2D black and white & color, 3D helicopter view & first-person view). This turns a two-dimensional plan into a three-dimensional experience – and a simple floor plan into a key component of modern real estate marketing.
