Two huge school extensions will be built at Locks Heath Junior and Infant schools to replace the huts.
It will mean that the 120 pupils currently using the temporary classrooms at the junior school – which have been there for 25 years – will have a permanent building at the Warsash Road site.
The projects will be funded via Hampshire County Council through the Department for Education’s Targeted Basic Need Programme – an £820m cash boost for a number of schools across England.
Three huts will be replaced at Locks Heath Infant School with three classrooms.
But the exact amount of funding for the two schools has yet to be announced.
Architectural plans are underway for the building work to replace the six huts at the junior school with six permanent classrooms – one of which could remain as a music room.
Head teacher Kevin Parfoot said: “It will be all under one roof which will be fantastic.
“We’re proud and delighted that the local authority is investing in what we believe is a great school. The quality of the learning environment will be better. Having the children all under one roof will lead to a real sense of identity in the school and feel as one school as opposed to classrooms and huts across the playground.
“It will mean for a year we won’t have a very big playground. We’ll be looking at whether we will need to have split shift lunchtimes.”
It is hoped the building work could start in May 2014 and will take 41 weeks to complete, meaning it would be ready for new pupils in September 2015.
As part of the scheme it is hoped a court area between the classrooms near the main reception could be converted into an orangery and that near the new classrooms there could be an outside space for whole school assemblies to take place.
The government announced the scheme to tackle a lack of school spaces across the country and nine other schools in Hampshire will be provided with funding for expansion to accommodate more children by 2015.
While the two Locks Heath schools will not take on any more pupils, the plan for the funding is to ensure more spaces can be accommodated at schools across the country with refurbishments and new builds.
The Department for Education could not state how much in total would be spent across the Hampshire schools.
