More classrooms and a start-of-the-art learning hub are being built in a £2.6m extension.
Construction and infrastructure company Morgan Sindall has been appointed to build the extension at the Locks Heath Infant and Junior Schools.
The project, backed by Hampshire County Council, is already under way on the schools, which share the site at Locks Heath.
The work to the juniors will comprise a four-classroom extension, toilets and a multi-use teaching area.
A state-of-the-art learning hub with a glass roof will be built.
The project team will create three additional classrooms at the infants.
The existing staff room will be extended and additional toilets added.
The classrooms will replace the current temporary ones and will link with the existing school building.
Tim Elliott, special works manager at Morgan Sindall, said: ‘The classrooms will give a new lease of life and, importantly, replace the temporary ones with an upgraded, permanent solution.
‘Morgan Sindall has extensive experience in delivering education projects both on time and within budget and we look forward to working in partnership with both schools as we deliver this project.’
The building includes solar panels on the roof of the juniors.
The new elements of the building are designed to get more natural light into the rooms.
