Construction is well under way at Butler College, which will become Princeton’s third four-year residential college when it is completed in the fall of 2009. At left and center are portions of two of the college’s three new dorms. At right is Wilf Hall, which will house unaffiliated upperclassmen. The large open area will be landscaped as an amphitheater. The new dorms, which are being built on the site of the former New New Quad, range in height from two to four stories and will have suites with private baths. More than half of the roof surface will be “green,” with soil and vegetation above a waterproof layer. The dorms include academic seminar rooms and a large “food emporium,” though the college’s main dining area will be in Wu Hall.
