To celebrate the 50th anniversary of its Novar Gardens campus, Immanuel College upgraded the school gymnasium.

A primary school oval was converted into the indoor basketball courts, and an existing auditorium and a new dance classroom were integrated into the new centre.

[9] The Margaret Ames Centre, named after an old scholar and ex-teacher, was opened in 2015 as the senior school for students in Years 10, 11 and 12.

The Discovery Program began in 2023 with a host of different elective subjects that offer more creative and expression-based experiences, such as 'The Joy of Painting', 'Podcasting', 'The Edit: Filmmaking'.

In 2019 the college has beds for 170 students, accommodation is in a main double storey building, self-contained units and eight fully equipped houses.

The houses are named after the word for "Peace" in various languages – Heiwa, Pengon, Tangokorro, Frieden, Shalom, Koinonia, Sama and Rahu.
