The room is based on real world scale. Based on my room at my dads house. Had the plans of the room as we just had it done out.

Cupboard Doors, TV, TV unit, storage boxes and XBox are all made to scale. Most of the others items are made based of these scales. Lost track a few times with the scale of things (the TV unit used to be way off). I am thinking the draws and bed maybe a little off but will get to that as I am going around the room.
