Sydney Builder

Your Licensed Granny Flat Builder in Greater Sydney

Greater Sydney is one of Australia’s largest and most diverse residential regions, with a mix of established family suburbs, growing communities, and strong long-term rental demand. Many Greater Sydney homeowners are adding a granny flat to their property to create additional living space, support family needs, or generate potential rental income. GrannyFlow is a licensed NSW granny flat builder (Licence No. 488676C) coordinating and managing projects across Greater Sydney — from initial site assessment through to completed build.

You are dealing directly with a licensed NSW builder — not a lead generation website or third-party referral service.

We have worked with homeowners across Greater Sydney and surrounding areas including Western Sydney, the Inner West, the Hills District, Parramatta, Liverpool, Blacktown, Bankstown, and nearby regions.
