I also like the third one, but where's the bidet?

I'm trying to utilize a cropping tool to help my fellow workers understand how to and why to crop a 3d medical image. What I want to do is show a 3d model of a house, front on from street level, then crop away the front wall to show the living room, crop away the living room and secondary wall to show the kitchen/bedroom, and finally to crop away the next wall and see the den, possibly the back yard. I've been working on this for a couple of weeks now and getting frustrated with a lack of knowledge of the tools available. Any help/advice would be sincerely appreciated.
