Bradford on Avon: Wiltshire Building Record Report on Shrapnell House. I'm pinning this because it is a splendid example of a technical write-up of a structure. Although this is NOT a full historic structure report (HSR), it IS a wonderful documentation of this building. If you have such a project, one that requires something short of an HSR, look at this for an example.
Vernacular Architecture Forum - Good place for discussion regarding vernacular architecture, which includes the vast majority of buildings in America. Vernacular may well have some hallmarks of classified styles and types, but nonetheless are considered vernacular because they are not entirely built in a certain fashion.
