The workmanship is courtesy of another board member.  Normally he builds very expensive home for the rich ($14 million was a recent one).  He has a crew that can do all this fancy stuff.  But with the collapse of the housing market, he is just hanging on these days and is looking for work to keep his crews together.  So he did the spectacular job and changed our preservation society bargain rates.  The guy is a living embodiment of the Instinct of Workmanship.  He does good work because he literally doesn't know any other way to do things.
