Proposals to create a new all-through school creating new secondary places have been given the go-ahead by councillors.
Members of Harrow Borough Council's planning committee passed the plans for the Whitefriars Community School in Wealdstone on Wednesday evening.
The proposals will mean broadening the age range at the school to include secondary school pupils up to the age of 18.
Plans include the redevelopment of the Harrow Teachers Centre, currently located next to the school in Whitefriars Avenue, and the construction of a two and three storey building.
Work will start in the coming months with the school’s first Year Seven pupils due to start in September 2015.
When completed, the school will offer three forms of entry for primary places and five forms of entry for the secondary school.
The school’s executive headteacher Chris Spruce said: "Now the planning and development stage of the process is complete it is amazing to see the building become real and begin to take shape.
"We are, as always, going to squeeze every learning experience possible out of this for the children and we know that the constructors, Kier, are very happy to support us in this.
"This is a golden opportunity for the school and our families to have the facilities that they deserve but we know it isn't the building that makes a school but the people inside it and we are very fortunate to be able take all of them with us on this incredible journey."
