A new primary school is being built to tackle a severe shortage of places in Oxley Park and Kingsmead.
It follows concerns over MK’s “unprecedented and sustained growth” in its pupil population.
A total of 420 children will be welcomed at the brand new school, plus an additional 26 into the nursery class and will be run by the Oxley Park Academy.
Last night the council granted permission to build on land off Merlewood Drive in Shenley Wood, which is a 15-minute walk away from the academy.
Councillors say it is expected to be ready in time for school starting in September 2017.
Conservative councillor Gerald Small said: “I am absolutely delighted with this decision which will mean that children will be able to go to their local school.
“The decision comes after a long campaign headed by ward councillors and supported by parents and the academy who have done their utmost to accommodate the extra demand for school places in the interim.”
There will be hard and soft play areas, sports pitches, as well as a three bedroom caretaker’s house adjacent to the school with a drive and garage.
The school is expected to employ around 49 full-time staff.
In July 2014, parents petitioned for the expansion of Oxley Park Academy after it turned away catchment children.
