Beginner - End game by touching certain object


I am totally new to Unity 3D and I have absolutely no coding knowledge. Basically all I want to do is to end the game when my player (standard Unity First Person controller) touches a FBX model of a house. Maybe by switching to another scene that would show an end game message?

Is there a simple way to do this? I guess a script is involved? I have a brief understanding of how scripts are attached and used but I have no idea how to go about actually creating my own. So far my google searches haven’t amounted to any concrete answers.
