tips for building house addition?

Question

I am hiring a contractor to build a home addition for me it will have a bathroom and a kitchen bedroom and a living and dining combo.
The addition will be about 600 square feet. I am enclosing a existing carport. I have told the contractor my hubby can do the heating and air I can paint it on the inside and my brother in law can do the plumbing. Any other cost cutting tips you guys can think of I sure would appreciate it!!
