The original Rimu Block building was built in 1932 and in its current state reflects the factory-style learning & architecture of the time; 3 cellular classrooms, bungalow-style architecture with verandah, bevelback weatherboards, hip and gable roof forms, large timber sash windows, and high volume spaces.

A 21st century learning philosophy promotes community engagement in an inclusive, multicultural, open and shared learning approach. The built environment needs to reflect and reinforce this ethos. The proposed alterations therefore intend to support various means of modern learning; both shared (through observation of others) and collaborative (group work).

Spaces provide easy surveillance for teachers with openness and transparency. Flexibility, acoustics, and visibility (openness and transparency) are paramount. The Shared Learning Space has breakout areas positioned on South side along existing structural lines.
