At the suggestion of a reader (Thanks, Tim!), I prepared a clean version of the map I worked from while writing the Nicole Tang Noonan mysteries so far. The original is sketchy, full of erasures and x-outs. This one, I hope, will help you picture the place described in the novels.
The chapel is the oldest building on campus, dating from before the Civil War. It served the Eden Commune and contains the mural Nicole studies in Dark Mural.
The Victorians on College Avenue were built in the late 1800s, when the descendents of the founders, having left communal life, turned the commune into the campus of the Eden Independent School. These were kit houses ordered from Sears and Roebuck.
The Old Classroom Building and the Library date from the 1920s when the school became a four-year liberal arts college. They were built in the collegiate gothic style.
Science Hall, a federal style building, was built in the 1950s. The Student Center, an example of early shopping mall, was added in the 1960s. The Arts and Humanities building, added in the 1970s is a fine example of modernist architecture.
The duplexes on Ohio Avenue were added starting in the 1950s. The Rabbit Hutches on Montgomery Avenue, where Nicole lives, are more recent.
The generic names of the buildings indicate the college has not yet sold naming rights to raise funds. Like many small schools with a long history, Fuchs College has survived on donations from alumni and the occasional grant.
Of course, this is all fictional, but I think it is a plausible history for a rural, liberal arts college.
