Kevin McElroy, Operations Director at ISG, said that indoor spaces for the school would been arranged over two storeys, allowing for the most efficient building shape, while maintaining a compact footprint and as much external space as possible.
The classrooms are split over both floors, with ground floor classrooms also providing direct access to outdoor learning spaces.
