Network Design

My company hired a contractor who is a CCIE and I have learned some good
things from him. But, still one question which I am not able to understand and
can't get an answer for - What is considered a good network design? The answer
I always get is "it depends". Understand that, so let me simplify in layman
terms so that I can grasp the concept ...
What is recommended if say you have a router (say 3945), a switch (say 6509)
and access switches (3750x). How does this fit in "The Cisco Three-Layered
Hierarchical Model".
Should I consider 3945 as Core and 6509 as Distribution and configure
InterVLAN routing on the 6509, OR, it's the other way around?
