Stop in for a cup of coffee

Not to nit pic, but he did not build anything. He drew plans for a certain look, then a structural engineer had to make it work. And that one was a real pain I have heard

Being a “builder” never means swinging the hammer. It is describing the architect and/or funder of the construction. No modern “builder” of homes does any actual construction themselves, they just procure the land, organize the contractors and fund the project. The modern ones don’t do the archetucture or engineering either, they contract it.
