Outside Structures - Close to Wall vs. Away from Walls

Hello,

I've noticed many different base designs take a different approach when it comes to outside structures.

Some base designs place the outside structures close to the walls, while others place them far away from the walls.
I'm just trying to understand the advantages and disadvantages to both techniques.


Here is what I have been able to come up with:

Advantages to having outside structures close to walls:

• Enemy troops are in range of defenses when they attack outside structures, I feel this would work best against barchers

Advantages of having outside structures away from walls:

• Pushes out the drop zone for enemy troops

Which method do you prefer? and if possible why?

close to walls to protect rss... and not give free percentage

The main objective of spawn forcing (placing structures spaced-out to increase border size) is to slow the speed of opponents' deployed troops, forcing them to be much more strategic in their timing. However, structures close to defenses can help lower the size of an attacker's army, giving the defender a big advantage.

I prefer to put my barracks, collectors and BHs close to my walls, at most one spot away from them :P
