All hands are on deck as construction is now under way for the major upgrade at Wilton Public School.
The multi-million dollar upgrade will be comprised of 22 new classrooms including additional support units, upgrades to the school hall, administration area, library, canteen, covered outdoor learning area (COLA), a covered walkway and a new car park.
The construction milestone was marked with the turning of the first sod by Wollondilly mayor Matt Gould last week.
Wollondilly MP Nathaniel Smith welcomed the start of construction and said he was delighted that Wilton, and other local communities in Wollondilly, were getting "their fair share of infrastructure investment".
"I am delighted that work has started. Every student in NSW deserves the best environment to learn and achieve," Mr Smith said.
"Wilton is situated in a beautiful part of south-western Sydney - a place where more and more people want to live.
"This project will meet the needs of our growing community, support local jobs and provide high-quality facilities for students and staff."
Mr Gould took to Facebook to say he felt "lucky" to turn the sod last week.
"The staff and students can look forward to 22 new learning spaces including additional support units, upgrades to the hall, administration area, library, canteen, and COLA, as well as a covered walkway and a new car park area," he said.
"Council has been calling for more investment into infrastructure and facilities in Wilton to serve the growth in that area for some time, so it's great to see this investment from the State Government into the future of Wilton, and I'd like to thank our state MP Nathaniel Smith for his significant role in championing this project."
Education Minister Sarah Mitchell said she was thrilled that construction was starting and set to be completed next year.
"I am proud that this government is delivering for the future of the Wollondilly region, and look forward to visiting the schools once completed," Ms Mitchell said.
