The proposed Seahaven Academy development is comprised of alterations to the existing Seahaven Academy school buildings and the provision of new accommodation to enable the one form entry (1FE) expansion.

Seahaven Academy currently has capacity for 750 pupils and it is intended to increase the capacity of the school to 900 pupils. The project is commissioned by East Sussex County Council (ESCC).

The refurbished parts of the school and the new extension will accommodate a new entrance area, administration suite, standard teaching classrooms, ICT/multi-use classrooms, activity studio and replacement staff offices.
