Dipping toe in the water with Google Cardboard

Hi
I have an idea and before wasting too much time or money on it, I would like to test one of the key hypothesis. To that end, I am looking to buy a simple room where I can use blueprint to add actions (play a 360 film) to e.g a TV or picture on the wall.

I was thinking if I could buy a sitting room environment with clickable areas, that would do me. This just needs to work with Cardboard using focus and activate to play by 360 film.

Any suggestions gratefully received

thanks
