In terms of missing middle housing...out of the 137,543 blocks of land in the ACT, 95% of the RZ1 and 85% of the RZ2 blocks are single-dwelling sites. That is approximately 8952 hectares of blocks with one dwelling. (ACT Government, Integrating the Missing Middle in RZ1 and RZ2)
If you could change one thing to make an impact what would it be? LVC reform, lowering the block size for additional dwellings or easing block consolidation rules?
