In this tutorial video, you will have an inside of the parametric house modelling. The video starts with modelling the basic geometry which is later transformed into the planes. These will be used as the reference planes for later elements. While the house is being modelled, it is also changed and altered in order to show the simplicity of modification. At the end, the planes are moved using a plane manager to show, how everything adjust to the height difference. The final part is choosing an angle and rendering the picture.
Here a beautiful example:
