A Harold Hill primary school hopes to double its intake with six new classrooms and a nursery.
The Mayor of Havering, councillor Michael Deon Burton officially opened Broadford Primary School's new state-of-the-art building in Farringdon Avenue.
Six new classrooms, a nursery, new sport facilities and a new outdoor area have been added to the school as part of the redevelopment.
Lois Nicholls, headteacher at Broadford, said: "The new building provides a much improved learning environment for the children of Broadford and I know how excited the teachers and children were when they moved into it.
"People involved in education are increasingly aware of the link between high quality learning environments and learning."
The demolition of the old building began in 2016 and since then staff and pupils have watched the site develop.
The new site has been named The Charlton Building after the first headteacher of the junior school, Miss Charlton.
Ms Nicholls added: "Modern facilities improve not only the school's physical environment but also its learning culture.
"But the building alone cannot add the vision and passion that guide the school's development.
"It is the interaction between our hard working, committed staff and children which will make the difference and ensure the new building supports higher levels of learning."
