• Something along the lines of a wall mounted modular locker with integrated vertical rack / locking point? - could be attached to any wall, could be modelled both to scale (multiple units along a wall) and full size without resorting to metalwork.
    The 'real life' situation could be any existing unused wall space. Look out of the window or door when you get to school/college (guessing, given A2): you will see both the environment and probably the potential users.
    You might even make one for real - much easier to test and evaluate than a whole building...
