Possible Layout

My Dad, although not the most handy, is a visionary. He may not be the best at doing the actual work but he has good ideas and here is what he has come up with for a new patio layout:

The pavers have a irregular shape, there is a spot for a table and chairs and a bench that separates the patio area from some flower beds behind it. The legend says "rocks" but it is more of a crushed rock that can pack down well as opposed to actual big rocks or pebbles so it retains a patio feel and not a flower bed feel. Behind the bench I might put in mulch instead of the gravel and plant sprasely. That area also gets a lot of shade so a garden probably won't do well there, however the smaller flower bed to the east would probably be a great place for a garden because it gets a lot of sun. I have always wanted to grow my own veggies so that would be exciting.
So that is the tentative plan, any thoughts, comments, suggestions?
