Why work with an interior designer instead of just a draftsperson, architect or builder etc?

Why work with an interior designer? Discussing various trades and their skills and knowledge.

One of the most common questions people ask is, "Why do I need an Interior Designer?" Why can't I use my builder? "I have an architect; can't they do it all?"

Well, I love to say I am a jack of all trades. I understand many different areas, but I am not a builder, cabinet maker, or draftsperson! The best way to answer this question is to look at each profession and what it can do. I have responded to these questions concerning residential buildings within Australia.
