Summary
Constructing a granny flat is a practical method to boost land utilization and rental cash flow. In standard residential planning, 60 square meters is a common maximum floor area threshold for secondary dwellings without triggering complex development controls. Property owners planning a granny flat should engage an experienced building designer early to draft compliance drawings, while factoring in professional lead times and local council approval processes before committing to construction contracts.
Key Points
Why it matters: Adding a secondary dwelling provides extra rental yield and capital value, requiring clear understanding of size restrictions and design workflows.
