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.
