here's an example of an interior design based upon a typical small house very common in Holland. I used an ordinary floor plan for this kind of house and changed it (alot); the attic is hidden in my pix.
This project was used to test the new multi-level feature of 3.4; well, i can say it works (3d camera view now really matches!).
The pictures are rendered horizontally to make better use of screen area [:D]. While looking at the images: left is the backyard, right is the front entrance/street side, top and bottom are walls shared with neighbours.
pic one is ground level (entrance is upper right door):

pic two is upper level:

pic three, at last, shows a composed image of the previous two:

As you can see, the bird view camera matches, i like it! And, we now have only one project file to cope with for our house designs!
Thanx, Emmanuel [:D]
hope you like it [:)]
