Do granny flats add value to a property?
Yes, in most cases significantly. A well-built secondary dwelling increases both rental potential and resale value.
Do I need council approval?
Most projects require approval under NSW guidelines. We handle the entire approval and compliance process for you.
How big can a granny flat be in Sydney?
Typically up to 60m², depending on your land size and zoning. We’ll assess your property and recommend the best layout.
Can a granny flat be custom-designed?
Absolutely. We create designs tailored to your lifestyle, budget, and the available space on your property.
How long does construction take?
Most builds take 8-16 weeks, depending on size and complexity. You’ll receive a clear timeline before we start.
Can I rent it out?
Yes, most homeowners use granny flats for passive rental income. We ensure your build meets all NSW requirements.
Will the new dwelling match my existing home?
Yes. We consider materials, colour palettes, and overall style so the new build feels cohesive and well-integrated.
