Fiction Adaptation - Set Design and Location Research

So John doe is a bit of the a social recluse, which reflects his character and will reflect his bedroom which he is shooting his monologue on. his backdrop to the video he is recording will be stuff to do with the attack, maps, people, buildings, plans, etc. Although not in the same context, the film 1 hour photo reflects this sort of collage of background that I am looking for, I will use a lighting kit to further illuminate the backdrop

Now on to the location. I have chosen my friends flat (who is actually going to be in the film) and we are going to transform it into a 'mothers basement' type deal. It is a relatively small flat, composed of a single bedroom, however, if we move some of the stuff around we can have a massive wall that is collaged.If we look at home videos of anders breivik among others, but i'llshare the video that is the most recent, Elliot Rodger is the latest mass murderer before topping himself guy, he realsed a video manifesto in the style that I want to shoot it - a guy talking to a camera phone and or small camcorder. This captures in my eyes how sick a human being can be and hopefully can be translated into a film. 

Also, a huge network TV show done the same efffect in one of their programs .Homeland, a story about a US army vet working for Al-qaeda, he also does a video a manifesto explaining his actions that are to come, I hope this explains how I want to set it out.
