Including my parents' suggestions, I redrew the floor plan with more generous dimensions. I was then nearing the end of my freshman year in high school.
My plan, shown below, also added extra storage closets to the garage, the master bedroom, and a hallway. Our house would have a basement (unlike the Georgia prototype), so I included access stairs from both the utility room and the back yard.
I specified a colonnaded front porch with a curved bow window, a feature that we had seen and liked elsewhere. And my own bedroom (room #8) grew from a cramped 11½ by 11 feet to a comfortable 16 by 12.
Our contractor used my plan to make his working drawings. The house was essentially built to these specifications, except for rearrangements of some fixtures and appliances.
