A ribbon-cutting ceremony marked the official opening of Abbey Farm Educate together in North Swindon.
Head teacher Emma Lindsay was joined by local parents, children from the reception and nursery classes and guests.
VIPs present included Annette Perrington, Director of Education, Inclusion and Skills at Swindon Borough Council, and Sam Nowak, CEO of Educate Together Academy Trust.
Abbey Farm joins four others run by the trust at locations including Bath and Bristol.
Head teacher Ms Lindsay, who began her teaching career at Lethbridge Primary School in Old Town, said: "It's very exciting - a brand new journey.
"We want to ensure that the school is here to serve the community, serve the children, that we create a thriving centre for this environment.
"This is a newish-build area, so the idea is for us to become part of the community so we pull everybody together."
Trust CEO Mr Nowak said before the ceremony: "This building and those responsible for its operation are going to be serving this community far beyond my tenure, and actually probably when these children, our first cohort that we are very proud of, are retired, we're still going to be working with children in this building.
"But in the more immediate future, our aim here at Abbey Farm Educate Together is to serve this community, and we want to do that by providing exceptional education."
The borough council's Director of Education, Inclusion and Skills, Annette Perrington, said after touring the building: "I'm impress by what I've seen.
"Having state-of-the-art buildings for our children is really important. Obviously, you've got historic buildings and they're fantastic, but when you start a brand new school, enabling parents to see what their children will be accessing is really important and we are really lucky."
