Why Exalt Builder for Your Granny Flat
We Handle the Council Process: Granny flat regulations vary between councils, and getting it wrong means delays and added costs. We prepare compliant plans, manage Complying Development Certificates or DA submissions, and make sure your build meets all the requirements from setbacks to fire ratings.
Maximise Your Block's Potential: Not every block is straightforward. Audifax's engineering background means we can assess your site properly, work around drainage challenges, easements, and awkward shapes, and still deliver a granny flat that feels spacious and well thought out.
Quality That Matches Your Main Home: We build granny flats with the same materials and workmanship as a full home build. That means proper foundations, quality fixtures, and finishes that last. Our Sydney building team doesn't cut corners on secondary dwellings.

Benefits of Adding a Granny Flat
Rental Income From Your Own Backyard: A granny flat in Sydney can generate significant weekly rent. It's one of the most practical ways to earn income from your existing property without selling, subdividing, or taking on a second mortgage.
Keep Family Close Without Losing Privacy: Whether it's ageing parents or adult children, a separate granny flat gives everyone their own space while keeping the family nearby. It's independent living with the security of being just a few steps away.
Increase Your Property's Overall Value: A quality granny flat adds genuine value at resale. Buyers in Sydney actively look for properties with compliant secondary dwellings because of the flexibility and income potential they offer.

Granny Flat Builder - Frequently Asked Questions
Under the NSW Affordable Rental Housing SEPP, granny flats (secondary dwellings) can be up to 60 square metres of internal floor area. That's enough for a comfortable one or two-bedroom layout with kitchen, bathroom, and living area. We design to maximise every metre within that allowance.
In most cases, you can build a granny flat under a Complying Development Certificate (CDC) through a private certifier, which is faster than a full DA. However, some sites or zones require a Development Application through council. We assess your property and advise on the best pathway.
Typically 12 to 16 weeks for construction, depending on the design and site conditions. The approval process adds another 2 to 6 weeks beforehand. We provide a clear schedule from the start so you know when to expect completion. Call 0400 789 018 to discuss your project.
