I drew out the plans for our present home of about 16 years.
I wanted about 2400.
A problem came up that the draftsman made that my builder caught.
I was to go overseas the next day and had only hours to fix it.
I made a quick change that satisfied my builder and myself that made it about 2500.
But, as we were building the upstairs, I added extra rooms and ended up at 2700.
