 In 2015, and in alignment with the celebration of the Sesquicentennial, plans commence for yet another refurbishing and re-interpretation of the foundational Packer Hall.Previously called the "Freshman Quad", the classic collegiate stone residence halls of Dravo House and Richards House now room freshman, while Drinker House is home to upperclassmen.All are massive stone structures composed largely during the depression, and are Lehigh's highest structures, with respect to altitude, outside of Sayre Park, and on the main (Asa Packer) campus.
