Kindly check the video in my profile of animating, and I wish you'll like it, I use SketchUp for modeling and Lumion for visualization and animating. I wish to see the plan and your needs and you vision of whats needed. Thanks.
I have experience with modeling houses from blueprints (in Blender 3D). I'm also Brazilian so we can speak in Portuguese if that suits you.
I can deliver a first version (polygonal mesh) of the model quite rapidly if I have the blueprint of the house
