The Avondale College school grounds feature a science and IT building as well as a gymnasium, a maths and science block,  sport fields, an astroturf complex, a theatre, orchestra pit and flexible seating which can hold up to 700 people.

Much of the school, including the gymnasium, was rebuilt after a large fire in 1990.

On 9 June 2006, the New Zealand Prime Minister Helen Clark visited Avondale College to open the new technical subjects building, the Ferguson Building, that had already been in use through the second half of 2005.
It is named after the head of the Chemical and Materials Engineering department at the University of Auckland, Professor George Ferguson, who for many years served the college on the Board of Trustees.

The school underwent renovations in 2010–11 which included the building of new science, social science, health, and dance facilities.

Former Prime Minister John Key opened the new mathematics and physics buildings, the C- and D-blocks, on 10 August 2011, which was then the biggest school rebuild project in New Zealand history.

In March 2014, a new atrium, two new two-story buildings, and new sporting courts were built.
