St. George's School's Nathaniel P. Hill Library on Feb. 4, 2013, officially became the only K-12 school building in Rhode Island to earn the coveted gold LEED (Leadership in Energy and Environmental Design) certification from the U.S. Green Building Council.

In 2010-11, the library underwent an $8.2 million renovation which added 4,500 square feet of learning and research space to the now three-story structure. The new building was designed by Boston-based Perry Dean Rogers/Partners Architects.

Overseeing the “green” construction was Boston-based Shawmut Design and Construction.

The building opened in the fall of 2011 with a number of innovative features worked into its enviromentally-friendly design—including locally-sourced building materials, energy efficient heating and cooling systems, and landscaped gardens sited to benefit from rain run-off from the library roof.

The renovated Hill Library is now at the center of the school's academic core and—along with cutting-edge technology and a collection of 27,000 volumes, 1,500 reference titles and audiovisual materials—houses the cutting-edge Merck-Horton Center for Teaching and Learning. A model for other high schools, The Merck-Horton Center encourages faculty members to adopt innovative teaching practices and helps learners of all types advance their academic coursework by providing peer tutoring in all subjects and by offering a number of Instructional Services programs with full-time faculty members.

The new library on the whole also features flexible classrooms, a multimedia conferencing facility, and individual and group-study spaces.

The school's archives are housed on the lower level.

St. George's, located on the hilltop overlooking Second Beach in Middletown, is an independent boarding and day school for 365 students in grades 9-12.
