 Hardenbergh 's design was described as employing both Gothic elements and classical forms that preceded the extreme eclecticism that was to mark a later Victorian Gothic Revival period . The original plans called for the building to be constructed out of red brick , but the final execution was mostly in sandstone quarried in Connecticut , with some examples of stone from Newark . Geology Hall , built on the south side of Old Queens , was the second of three projects that Hardenberg designed for the college , following an addition to a building ( now Alexander Johnston Hall ) that housed the college 's grammar school ( now Rutgers Preparatory School ) the year before . The third project , Kirkpatrick Chapel ( 1873 ) , was designed to complement the simple Gothic Revival style of Geology Hall and was erected on the north side of Old Queens .
