The project comprises the development of the former Chineham Primary School in Popley, Basingstoke to form the Austen Academy.
The academy will be a 125 place all-through special needs school with associated car park as well as play areas and sports facilities. The existing Nursery on the site will remain in place.
This new school has been built to meet future demand for places for pupils with special educational needs and will have a focus on children with social and communication difficulties.
Completion on this project is expected in the next week whilst the children are due to occupy the new school early 2021.
The Austen Academy will form part of a £10 million investment from Hampshire County Council working with the Department for Education to build the school. The school will be operated by the Catch 22 Academy Trust.
Executive member for education and skills at the county council, Cllr Stephen Reid said:
The school is required to meet the future demand for places for pupils with a social communication need or autistic spectrum disorder in this area of Hampshire. This facility will reduce the need to place pupils in non-county establishments and avoid transport costs by providing the places close to the area of need.
Once fully operational the school will cater for pupils aged between 4 and 18 years old.
