When you have a small space you have to deal with your main light spilling onto the background, the walls on the side getting in the shot, etc. With space like you have you can separate the main light from the background light and don' have to worry as much about light bouncing all over the place.
You want honest? i was looking for an answer that is so deep or analytic about my space, like to say place your model 6ft far from background, place your main 4-5ft left or right your model, place your hair light at specific distance and so on, now all of you saying that it is good enough space so now i hope i can locate and place my lights and model in proper distances within that space.
