PDT obtained state government approval from the Department of Environment and Heritage Protection for the proposed landscape works and minor building alterations.
Due to its heritage listing it was critical to retain the existing character of the building reflecting its rich history. Part of the building was originally constructed during the late 1860’s as a residence for Sir Charles Lilley around the time he was Premier of Queensland. The building has undergone a number of adaptations over its long history including a period from 1912 to 1954, as Emmanuel College. In addition to maintaining the heritage appeal and essence of part usage, it was essential to provide a comfortable and functional working environment and enjoyable landscaped exterior.
A formal style garden was developed as part of the landscape architecture complementing the building with a plant palette from the Oakman era.
