Accurate 3D site models ready in minutes

Moondoor Sitemaker helps architects, urban designers, and BIM professionals turn real-world spatial data into clean, detailed 3D geometry, including terrain, water, and trees.

Choose a location, generate your model, and download a BIM-ready base without manual tracing or file cleanup. Delivered as clean, well-structured IFC files, ready for your workflow.

1 . Locate Your Site

A digital site model - before your coffee gets cold

Select any location in the Netherlands using precise coordinates and instantly generate a site model based on accurate spatial data. Start designing with real-world context, mapped and visualised directly to your project location.

2 . Add Data Layers

All your site data - in one place

Explore the spatial information that matters most to your project, from zoning plans and permitted building volumes to ownership boundaries and cadastral data. Toggle layers on and off to quickly understand constraints, opportunities, and context.

3. Choose Terrain Model

They say The Netherlands is completely flat - but we know better

Moondoor Sitemaker transforms accurate spatial data into detailed 3D geometry. Terrain, water, rivers, canals, lakes, and trees are all included, no digital stone left unturned.

Prefer a simpler base for quick edits or fast visual studies? You can also choose a flat 2D terrain model, ideal for early concepts and “quick-and-dirty” renders where detailed height differences aren’t needed.

The 2D model is available at a lower price, and if you choose the 3D terrain model, the 2D version is included for free.

A site model that adapts to your workflow.

4 . Download IFC Files

Built to improve - your BIM workflow

Download all selected data as clean, well-structured IFC files, ready to use straight away. No messy exports or manual cleanup needed. Simply import the model into tools like Revit, SketchUp, or Archicad and continue designing.
