Yeah, and the ... place.  was.  trashed.

The office I'm in now is the only room on the second floor that didn't have to have the ceiling replaced.  (Water doesn't do a bit o' good to lath and plaster.)  That meant tearing down the old ceiling and replacing with sheetrock.  By myself.  Fun, but of the mild sort.

We think it was built around 1905 in the standard Territorial style of the era.  The exterior walls are double brick adobe 20" thick.  There is a central hall on both floors as a breeze way with large transom windows meeting the ceilings over the exterior doors.  The interior doors have transom windows also.  Downstairs the ceilings are 10' high, upstairs 8'.  The interior walls and ceilings are lath and plaster except where I had to remove and replace with sheetrock, mudding, etc. due to damage of one sort or another.  I have lathed and plastered in the past but there was too much of muchness to afford the time (and energy) to replicate the original construction.

Let's see, what else ...

The interior is double-cantilevered over the the exterior walls and central hallways carried down to 10" x 10" posts on stone for a foundation.  The exterior foundation is about a foot of dry laid flagstone.  

The roof is the old 1/4" corrugated steel held off by the most bizarre mish-mash of struts I've ever seen.  It seems they used whatever odds & sods they had lying around. It works so ... what the hell.

Apparently, and I haven't checked with the local history museum, the building had commercial spaces on the first floor with apartments/rooms on the second.  The Great Room was constructed by knocking out the interior walls sometime in the late teen's or twenties to be used as the 'meet and greet room' when it was a brothel.
