I stumbled across this lovely little bit of history, someone recreating his family's 1912 farmhouse in virtual 3D. Sparking this project was the discovery of original blueprints (actual blueprints!) and old contracts for that construction, as well as some delightful old photos. Take a look at the Mason Farm HERE. (I'm thinking of a similar, much less ambitious project of my own, actually, so I was especially impressed.)
Blueprints, that archaic tech - believed public domain
How much fun it is! And how addictive! Because, of course, there's always just one more little bit of information out there waiting for the researcher... I'm hopelessly addicted to research myself and have watched a number of others succumb, most recently someone introduced to the genealogy bug, which is a particularly virulent strain of the research infection.
Research is one of the great joys in theater design.
