How much should I charge for a house design/construction drawings that I have already done once before?

Question

I recently designed a 3000 s.f. house with construction drawings that another client would like to build. Because I own the design, I can sell the already completed drawings. But what do I charge...I am essentially selling something that the work is already done. Any thoughts on this would be appreciated.

Answer 1

Standard amount that you charged before, assuming that you'll make any design changes to be site specific.

I'm a professional engineer; sometimes I lower my price depending on the customer or work involved, but I keep it high enough so that they appreciate the effort that has gone into the design - whether it's a copy or not.
