A sod-cutting ceremony has been held to mark the start of work on the next phases of the transformation of Crownbridge Special School.
Phases two and three of the project are being built on the 42-acre grounds of Croesyceiliog Secondary School, following the successful completion of phase one at Penygarn Primary School three years ago.
The council has worked in close partnership with Crownbridge and Croesyceiliog staff and governors over the last three years agreeing the vision and strategy for the new school. The new £8.2million facility is being built with Welsh Assembly Government support.
The executive member for children and young people, councillor Mary Barnett, said: "The integration of pupils at Penygarn has been a huge success. Both head teachers agree all children are benefiting from the experience and this new facility in Croesyceiliog will completely modernise and transform additional learning needs education in Torfaen.
"By having these phases on a single site, we are making the best possible use of resources. We are also improving our inclusive education system, by providing a wider range of specialist facilities and equipment to meet pupil needs.
"Most importantly, it will ensure all available money is spent where it is needed most - on meeting the needs of our most vulnerable children."
This project will further enhance the reputation of Crownbridge and Croesyceiliog as strong performing, well-managed schools with new facilities that will enable many more children and young people to have their needs met in the county.
The development will include a hydrotherapy pool and a sports, dining and assembly hall.
Construction is expected to be completed in the autumn of 2011.
