Ok. After doing a little bit of research, and talking to the administrators at Chantilly High School (who are much more talkative about building design than the administrators at prisons, I might add!), I found out a good deal about the rhyme and reason for the modular, block layout of the school.
It was constructed during an "open classroom" phase - where all the fad were classes without walls, supposedly to encourage student thinking, and whatnot. Anyways, Chantilly was built to be temporary, lasting about 5 years. It's since stood 20 years longer, so it's obviously had some renovation done.
But that's off topic. Chantilly's modular "blockish" design was centered around how the students were supposed to be organized, by subschool in the original "open classroom" design.. This organizational pattern is kept to this day, with four seperate subschools, and instead of geographically dividing up the students by where they are in the building, they're divided up alphabetically into four groups, with a fifth subschool running the Special Education department. Each "sub-section" of the school is responsible for a particular activity, or type of activity - fine arts in one section, vocational in another, special ed in a third, etc.
Here's what it looks like, Graphically.
On the prison front, I haven't found most prison administrators too willing to disclose a lot of information about their prison. I suppose it's for security, which is in fact a valid concern, but I'll have to find a prison that really fits the bill, and then really plead with them for generalizations :)
On the plus side - I've found that there is a company, called "Modular Building Systems, Inc" (MBSI) that manufactures modular units for both schools AND prisons, which confirms the myth that companies who design/build schools also build prisons. Especially since Chantilly HS was built as a modular school. Jackpot!
I'm searching for prisons that are as equally (and nicely) divided up into sections as the schools I've looked at. There are a lot of prisons in the US, which makes the search a little tougher.
Anyways, B out!
