Interesting to hear that some people think the CMU campus is ugly. Other than a few buildings and that stupid pedestrian pole to the sky sculpture thingy, I think it is excellent.
It is high density but has grass lawns for summer activities and events. They've done an excellent job of making it pedestrian friendly. I love all the nooks and crannies in the ravines between some of the buildings. All of the buildings are fascinating in their own ways. CMU even has a mater plan that details expansion decades into the future.
Just goes to show that criteria for beautiful/ugly can differ drastically.
On my list of changes would be:
* Plant more trees
* Get rid of the horrible pole sculpture
* Make Forbes Ave a pleasant section of the urban Fabric. Currently it best avoided. This means narrowing Forbes to two lanes, landscaping, etc. The Tepper Building/Quad currently under construction will completely transform the area. Thankfully I think that CMU is actively pursuing the narrowing of Forbes.
* Put a new facade on the front of the Purnell and University Center buildings. That's the side that faces forbes ave. The new Cohen Center should address this although I don't consider it to have good architecture.

Edit: In regard to the comment that "Most of the newer buildings and features are just kind of plopped down wherever with no consideration for how the play with their neighbors". Having been a student and employee, I was constantly amazed at how well all the buildings are connected. Amazing public spaces are everywhere! Basement skylight lounges, high-level niches with seating, catwalks with spectacular views, balconies, etc. There is an astounding number of pedestrian routes that wind through various eras and styles. It takes years to discover the well evolved network of passages, bridges and tunnels.
There is a hodge-podge of styles but in terms of usability and human factors, I give it an A+. Very few campuses are that well connected, especially those built over the course of a century. Opinion on this seems related to the weight one gives to quality and function vs purity of form. I like both. To me CMU is an example of good design that can initially look haphazard.
