Pure project -- maquette

My model of the gym - to scale (2cm=1m) . I've adapted my first idea in fact because it wasn't viable within the time scale -- i.e. in 3 hours 7 of us have to assemble it in the gym, photograph it and take it down. I don't think anything will prove viable, actually. But perhaps that's the point. Maybe we're meant to learn that our site-specific project won't work without tight time management. So lots of compromise on interpreting the brief. Result is that my reading of 'pure' is 'plain' or 'simple'. As opposed to: absolute; genuine; unalloyed; spotless; disinterested; chaste; utter; in tune; clear ... etc. etc
