i am VERY leery of anyone that wants a percentage of anything. and simply
put, the cost of the design has very little to do with the cost of the
build.

That's not really true. It CAN be true sometimes, but isn't always true.
I've done some very intricate, detailed work that cost much more to design
than the same "square foot" of a simple design.

I would agree that determining the actual fee based on the cost alone is an
unwise idea. I only give a ball park range when someone asks what a fee
might be. Then I offer them the option of a fixed fee (which is determined
after a better understanding of the project is obtained), or straight
hourly.

i could design a very labor intensive addon, or specify higher cost
materials, but that doesnt mean its a better design or that it would
actually take more time to design it.

It all depends... for instance, if you spec. out standard plastic laminate
counter tops, the amount of "design" work is less. But what if you spec.
out a custom laminate top? Or a floating top with special supports to make
it appear as if it's floating?


but to be honest; 100k for a 500 sq ft addon? if you think that sounds
even
remotely reasonable you got money to burn and need not worry about the
costs
anyway...

It depends on the addition...a custom master bath suite could easily run
$100K... Also, if it's 500 sq. ft. / floor, then the addition is a 1,500
sq. ft., not 500.
