How tall is the building?
A single building's footprint as GeoJSON, with height in metres and floor count in the properties, ready to be raised as a simple 3D volume without a full IFC file.
Nøkkelen virker i dag på Leietaker-API og dagens Data API; Placepoint API godtar samme nøkkel når det lanseres.

From building number to footprint
The call tells you exactly where a single building stands and how tall it is, not just the property's overall boundary. Developers building their own 3D visualisations need a footprint and height per building to raise a simple volume model, insurers need roof area and volume for damage calculations, and municipalities need the same geometry that sits in their own FKB register to compare against Placepoint's copy.
The answer is a GeoJSON object where geometry is the building's footprint as a Polygon, and properties is filled with heightM (height in metres) and floors (number of storeys), unlike a property boundary where the same fields are empty, see Plot boundaries. The building is fetched with a buildingNumber from the property's building list, not from the building alone, so a building that has been demolished or no longer exists on the property returns 404.
Footprint and height are enough for a quick massing study before anyone has drawn an actual 3D model: ground area times height gives a volume estimate, and the floor count separates a tall building with a few large storeys from one with many small ones. It is a quick starting point for early-stage design, before a detailed model is imported into 3D-Designer.
Footprint and height in the same object
heightMandfloorsfill the properties where a property boundary has empty fields, see Plot boundaries.Enough for a quick massing study
Ground area times height gives a volume estimate before a detailed model is ordered or imported into 3D-Designer.Building number from the building list
buildingNumberis taken from the property's building list, not from the building alone, so a demolished building returns a clean 404 rather than an empty object.
Fields that actually tell you something
One GET call with a matrikkel number and building number gives you footprint and height. The fields below are the ones that decide what you can build on.
