I toured a "several-small-buildings" home in Travis County, Texas (central texas). It was primarily owner-designed and built. He did have a fairly big piece of wooded property which sloped steeply down to a creek. At the street was his mailbox and garage/office/barn which was the largest structure and put on a good face for the normals. Behind this and sloping down into the woods he built several structures including 2x1-bedroom structures, one kitchen/dining, and another small studio. They were extended along one slope of the creek and arranged in-line, rather than around a central courtyard. Each appeared to be smaller than 200 sq-ft. They were all connected by paths and covered patios. Lots of outdoor living. Electrics were run between the structures and lights were installed along paths. Although, the owner designed the whole thing, it was not built on the cheap. All materials were delivered to the street and transported by wheelbarrow down the slope.
I'd call it a 'compound' rather than a campus.
