It’s here that Australia’s most successful hip-hop act is finalising their new single.
The question I’ve asked J Emz - does OneFour have gang links? - has long stalked the group.
To fans, the rappers are pioneers: five Sāmoan-Australians from one of Sydney’s poorest postcodes who have used their explosive sound to give voice to millions of marginalised young people.
But to police, OneFour is a threat to community safety, to be managed and contained.
For years, they have blocked the group from performing at home by arguing their music incites violence - triggering a complex debate about art and censorship.
This is really not world news worthy mate.
But have you considered those drill rap teens need to get off our lawn?
