The Innovation Campus: Building Better Ideas

Personally I think this title is very clever. Lange uses a very clever play on words that not only provides a creative title, but also hints at the main idea of the article. The title suggests that not only are ideas themselves built, but by building buildings to facilitate creativity, you can both figuratively and literally build more or better ideas.

[S]tudies have shown that proximity and conversation can produce creative ideas (Par 4).

From my personal experience, this is very true. Inspiration is very much a product of certain experiences or conversations, and while some may be found by observing nature or other systems, a significant amount is a result of interactions with others.
