OpToPo is here to help cities reach new heights! With our smart, data-driven platform, we make it easy to spot which buildings are ready for extra layer(s). Whether you're a municipality, developer, or housing corporation, OpToPo provides clear insights into where and how you can add new levels to existing buildings, boosting both living space and sustainability. Think of us as your go-to guide for smart urban expansion—helping you tackle housing shortages while making cities greener, one rooftop at a time!
We handpicked a few key criteria that really make a difference when it comes to optoppen. Using open-source datasets, we gathered data for each one and set up a scoring system. For example, the flatter the roof, the higher the score. Each criterion also got a weight between 0 and 2, depending on how important it is compared to the others. Maybe you care more about the roof type, while someone else might prioritize the building's energy label, especially if they’re thinking about a renovation combo. All these scores are then combined into one overall score, shown on the map, giving you a clear picture of the building’s potential.

Roof type: The type of the existing roof, where a singular flat plane is most optimal and a fully sloped roof is the least desirable. This criteria is calculated using the angle and surface area of the 3D roof planes of the building.
Remaining height: The remaining height that can be added to the existing building without the need for additional permits. This is calculated by subtracting the maximum allowed height from the current building height.
Energy label: The current energy performance label can depict a building’s suitability for the combination of opptoppen with sustainability measures. The lower the current mean energy label, the higher the score is.
Environment: The distance to surrounding buildings is used to give a picture of the potential feasibility and effect of adding an extra layer on the direct environment in ters of sunlight and construction equipment access.
