The Engineering Complex at UNB is comprised of five buildings, all constructed at different times, and physically connected as one. The first building constructed in 1901, was the original Engineering Building, designed in the Romanesque Revival style, followed closely thereafter by the former Gymnasium, converted in 1944 to the Electrical Engineering Build-ing. In 1957, an expansion to the western side of the two original engineering buildings was made. Sir Edmund Head Hall, a five-storey, 13,600 sq.m (140,000 sf) addition was con-structed to the north of the previous mentioned buildings. Gillin Hall was added to the west side of Head Hall in 1989 and the Information Technology Centre was added to the south of Gillin Hall along Windsor Street in 2000.

In April of 2017, UNB requested Murdock & Boyd Architects to come up with a design solution for a new prominent Main Entrance to the Head Hall Engineering Complex, one that celebrates the engineering programs that are delivered at this institution. The space is designed to allow for and promote the collaboration and interaction of students and faculty, provide for additional graduate study areas, larger crush space from the Dineen Auditorium and a space to exhibit and visually celebrate all the disciplines of the world renowned UNB Engineering programs and its graduates.
