A recent visit to Notre Dame reveals a lot of construction next to DeBartolo Hall.

Google reveals that there’s a whole site devoted to ND architecture.

It reveals that this giant hole in the campus is a massive addition to the law school:

The new addition to the existing Law School will be located directly south of the existing building on a site once occupied by the campus post office.

The addition will be three stories plus a partial basement totaling 85,500 square feet. The materials and overall design compliment the original Law School building.
