An addition to your home can be troublesome. Building department staff really just try to do their jobs and be helpful, but sometimes that leads to conflicts between what you want and what is possible. Trying to do things both right and cheaply, this man asked me to come out and suggest solutions to a couple problems he had with the inspectors, who wanted everything built exactly as shown on the drawings. He wanted to move a door, and eliminate a short wall, both of which I suggested alternatives to. I wrote a letter, made a calculation or two, and solved his problems. Engineers are awesome.
Anyway, the best part of the work is the fabulous chicken curry his wife served me for lunch.
