Why so small? I like the BBQ to be away from the seating area to avoid smoke that space really doesn’t allow that

Write down your budget. Get some builder's paper and make a space 12 by 12 feet. Then put your current table and chairs and BBQ on it. The BBQ should go in a place that allows smoke to escape freely and not up against a wall.

Sometimes people use expandable patio tables to have a comfortable space most of the time and a tight but reasonable fit when there are guests. Extra folding chairs can be kept in the garage.
