Broke ground for the new garage

When I built my garage in 2013, I drew up a sketch on a sheet of paper and took it to the city planning office to get the building permit. They advised me of a few changes that I needed to make, which I did on the spot and had my permit. Took the same sheet of paper and an additional sketch I had drawn for my trusses to the building supply store and they were able to calculate the materials and have the trusses built to my specifications.
