It's a national level competition, open to all architecture students. This year you had to redesign or retrofit your department of architecture building. If you're really interested, you can get the brief here.
Other winners from our college include Anuj and Kabilan who won first (w00t!), and Ammani and Amri, and Aditya Wallabh (who partnered with his sister at MANIT, Bhopal), who also got a commendation.
If you can't see the above, you can also see our entry here.
