It serves as the headquarters of the Knox City Council. The Knox City Council's building was burnt down in 1994, and took a few years to be rebuilt. It is now a meeting place for councillors and the Mayor.
Another Wantirna South attraction is the Knox City Shopping Centre, which was first built in the 1970s. It had a major refurbishment in 2002 to make it a more popular area for young people. This area is now known as Knox O-Zone, a popular night spot containing a pub, restaurants, clubs and cinema.
Knox Police Complex is situated on Burwood highway opposite Knox City Shopping Centre.
Another important building, across the road from the Knox Council headquarters, is Rembrandts. Rembrandts was a ballroom and formal eating place where social life took place, including over-28s and debutant balls from various schools. It is currently for sale for property development.
