What is the best way to get a house into your project

What is the best way to get a house? Is there a good & easy software (for mac) or should I just download a model off of the internet. If so what’s a good website?

Software (not sure about mac compatibility) : Blender, 3DS, Cinema4D, Sketchup, need help here :stuck_out_tongue:
