Building of Lilydale Adventist Academy's facilities commenced in 1963. The builder, Mr. Crabb, and his team, worked tirelessly to complete the school facilities in time for the commencement of the school year on February 10, 1964. In operation at the commencement of the 1964 school year were school administration and classroom facilities, and a boy's dormitory. At the same time, four staff homes were constructed on the property by Mr. Stoneman and Mr. Epps. The girl's dormitory was added and in operation at the commencement of the 1966 school year. Subsequent building projects have included: cafeteria, student chapel, Art and Technology facility, Science facility, assembly hall, and gymnasium.
Further developments have been the construction of the primary school, then known as Edinburgh Adventist Primary School in 2000 and the Edinburgh Early Learning Centre was added to the campus in 2006 providing continuity of education for 2 year olds through to Year 12. Ongoing developments over the past ten years include the refurbishment of the Science Labs, Art and Technology facility, conversion of the girl’s Dormitory to a new Languages Centre and a new Library Resource Centre has allowed for a contemporary educational environments to enhance learning and teaching.
In its 50th year of operation the Administration offices have been refurbished and updated.
