1799 description of rooms in the public buildings including apartments for servants

I'm not sure who wrote this December 14, 1799, description of the public buildings that gives the number and dimensions of most rooms inside them. It reminds us that these were not simple buildings easily constructed. Unfortunately, there is no description or characterization of the men who built them nor mention of the architects. Twice the writer points out that in the basements of the buildings their are apartments for servants.
