For the next few months, the Australian state of New South Wales is offering house plans, with fast tracked planning consent, for just $1.
The NSW Housing Pattern Book has low-rise designs, with eight different options on offer for home builders.
The state's Planning Minister says the designs will help speed up the delivery of new homes.
The $1 cost for the house plans is in contrast to a typical price tag of around $20,000.
They are for so-called low-rise housing - semi-detached homes, terraces and apartments, not free standing houses.
Each pre-approved pattern includes an accelerated planning pathway and the technical information necessary to proceed with building.
One of the architectural firms whose designs feature in the pattern is Sam Crawford Architects based in Newtown in Sydney.
