As an architect, we were taught the concept of "defensible space" which is basically a theory that states an area is safer when people feel a sense of ownership and responsibility for that piece of a community.

May need to involve an architect very early on in the discussion and be prepared to shell out some cash for the feasibility study - or atleast a free dinner or two!

I did not use architect or engineer because it wan not necessary.

I've been looking at a software called Chief Architect (because of how simple, advanced, or extensive, and in-depth it can be depending on how deep into it you want to go and what your plans are), as well as AutoDesk homestyler.

Also, I prefer the AIA (Am Architect Assoc) contracts and language for boilerplate, as it is more pro-client than the clauses general contractor's associations and attorneys draft.

Should we consult a designer, architect or space planner or??  

You can either pick a plan already designed from the company or hire an architect to do a custom one.

I'm in the early stages of hiring an architect.

One reason for this is that I’m a licensed architect.

He is an architect in Oak Park, but he can do structural reports as well.
