Following the rebuild the school will have capacity for 600 students. The new facilities will include a new learning block, library, administration building and Rumaki Whānau Ata, the school’s Maori Immersion Unit.
The new learning block will be an innovative learning environment, which will have flexible learning spaces.
The school's board of trustees is contributing $1.2 million towards a new multi purpose hall.
Freemans Bay School acting principal Janis Powley says staff, students and parents are thrilled that the school's redevelopment is now under way.
“It will be a carefully phased development that will result in buildings designed to support the 21st century teaching and learning style that we are already delivering.”
During the summer holidays pre-construction work was carried out on site and earlier this week the site was blessed by local kaumatua.
Work is expected to be complete by the end of 2017, ready for students to begin the 2018 school year in their new facilities.
