Cedeon Design - http://design.cedeon.co.uk/portfolio-entry/2014/proposed-fishing-lodge/
We recently created an accurate BIM model for a UK Building Regulations application of this proposed lake side fishing lodge. We then imported this model into Blender along with the meticulously recreated 3D topography from survey data to create the image below. All the foliage was created in blender. The whole piece took around 3 working days to complete.
