The School of Engineering in Athlone Institute of Technology incorporates facilities for six departments within an environmentally responsive envelope achieved through the exploitation of orientation and materials. The project forms mats of open and closed space, combined to form six bars of accomodation linked by a circulation spine; courtyards are eaten out of the rectangular plan in a regular pattern, treated randomly. The space is covered by a sloping metal roof which provides a developed section of single and double-height spaces within a common building line - classrooms to the front and highly serviced, double height laboratories to the rear.
