How Much Does a Granny Flat Cost in Sydney?

The total cost of a granny flat depends on far more than the floor area. Site constraints, design complexity, approvals, services and construction choices can all change the budget.

Start with the site

Before finalising a design, check the block, access, existing structures, slope, services and the planning pathway that may apply. These factors can affect what is practical and what documentation will be needed.

Budget for drafting and approvals

A granny flat project typically needs clear plans and supporting documentation before it can move through its approval and construction stages. Getting the drafting scope clear early can reduce surprises later.
