 The university assumed ownership of the now @-@ disused observatory building and was originally going to abandon it . Louis Beaufort Stewart , a lecturer in the Faculty of Applied Science and Engineering , campaigned for it to be saved for the Department of Surveying and <unk> . He eventually arranged for the building to be re @-@ constructed on a more suitable site . Demolition work was carried out in 1907 : the stones were simply left in place over the winter , and were used the following year to construct a re @-@ arranged building just east of the main University College building ( south of Hart House ) .
