Sorry it took forever for me to share these with you. I had to save my uni lot to the bin and place it in Sunset Valley so I could move a sim in to test it. Then, of course, even though I have cookies and history set to delete on exit and run ccleaner, I could NOT log in to my launcher. So, I had to research some and then open the safety tab of Internet Explorer to uncheck that first box and check the next two to really clear the caches. Oh my!
Any way, the lot I built for uni, I placed just across the street from the uni center so it'll be centrally located, close to classes and parties and places to hang out. It's here: http://www.thesims3.com/assetDetail.html?assetId=9159098 (pics in the upload). I called it Micro Magic. It's larger than the 16-tiles because I added a full bath instead of an all-in-one.

Then, I built another in Sunset Valley while I was at it in a 10x10 lot I placed next to the beach on the road to the Wolff mansion.
It's here: http://www.thesims3.com/assetDetail.html?assetId=9159097 (Again, pics are in the upload.)
It's actually 17 tiles because of those two half-tiles, but I really like this one!
