The opposition will push the government to scrap a 120-square-metre limit on secondary dwellings permitted across large areas of Canberra's suburbs under a new planning system.
The Canberra Liberals say the size limit will prevent a wider range of housing sizes coming onto the market and will mean large blocks in older suburbs remain underutilised.
Peter Cain, the party's spokesman on planning and land management, will on Wednesday move a motion in the Legislative Assembly calling for the government to scrap the restriction, which applies to second dwellings on RZ1 blocks larger than 800 square metres.
