The £4m deal for the design and installation of bricks and blockwork at the new Alkerden Academy will see Winchmore start on site next Spring.
Alkerden Academy will offer more than 2,200 pupil places, making it one of the largest educational facilities ever to be built in Kent, occupying an expansive 11.1-hectare site.
Located in the Whitecliffe Eastern Quarry Development the education hub will feature an eight-form entry secondary school, up to five-stories tall and a two-form entry, two-storey primary school.
The campus will also include a community sports hall and sports pitches together with related car parking and access roads.
Construction is expected to complete in July 2026.
Pat O’Hare, Regional Director at Graham, said: “Our team is dedicated to delivering a facility that not only meets the highest standards of sustainability but also provides an enriching environment for students and the community.”
