GUILDFORD Grammar Preparatory School students from years 1 to 6 will start term 4 in new classrooms.
The $22 million development was designed for flexibility, with classrooms devoid of fixed furnishings so spaces can be rearranged to accommodate learning needs.
Classes can also be linked or closed off as separate units.
The architecture takes advantage of the site and the views of the wetland and floodplain.
The development incorporates a new administration building on top of a new cafe.
