Can I build a granny flat on my Northern Beaches property?

In many cases, yes. Whether your property is eligible depends on factors like block size, zoning, and existing structures. Northern Beaches Council and North Shore councils have specific rules around secondary dwellings. We can help you understand what’s possible on your block and guide you through the approval process.

Do I need council approval for a granny flat?

Most granny flat builds require either a Development Application (DA) or a Complying Development Certificate (CDC). The right pathway depends on your property and the scope of the build. We work with designers and engineers and can help coordinate the approvals process as part of your project.

What’s the difference between a granny flat and a secondary dwelling?

They’re the same thing. Secondary dwelling is the planning term, while granny flat is the common name. Both refer to a self-contained living space on the same lot as the primary dwelling.

Can you renovate an existing structure into a granny flat?

Absolutely. We regularly convert garages, outbuildings, bungalows, and other existing structures into quality granny flats or studios. It’s often a cost-effective way to add a secondary dwelling without the expense of a full new build.

Can a tennis court be converted into a granny flat?

Yes, this is one of the most popular options on larger Northern Beaches and North Shore blocks. A redundant tennis court offers excellent space and usually a good footprint for a well-designed secondary dwelling. We’ve done a number of these conversions and can walk you through what’s involved.

Can the granny flat be rented out?

In many cases, yes, but this depends on your council’s rules around secondary dwellings and whether your approval allows it. We’d recommend confirming this with your council or a planning professional as part of your project planning.

How long does a granny flat build take?

Timeline depends on the size and complexity of the project, as well as how long council approvals take. We provide a clear schedule upfront once approvals are in place, and keep you updated throughout the build.

Do you handle electrical and plumbing for granny flats?

Yes. We have qualified trades for all electrical and plumbing needs, and can work with suppliers to source and install your preferred fixtures and fittings, from practical essentials through to more bespoke finishes.

Can you add a deck or pergola to the granny flat?

Absolutely. We regularly combine granny flat builds with a deck or pergola to create a complete outdoor living environment. Both elements are designed together so the proportions, materials, and finishes all work in harmony.

CUSTOM GRANNY FLAT BUILDERS NORTHERN BEACHES

Our Granny Flat Services

We offer a full range of granny flat design and construction services, all managed by one team under one contract.

New Granny Flat Construction

We design and build custom granny flats tailored to your block, your family’s needs, and your budget. From a compact studio to a fully self-contained one or two-bedroom dwelling, we manage every stage, design, engineering, council approvals, construction, and finishing, so you don’t have to juggle multiple trades.

Granny Flat Renovation

Already have an existing structure? We can renovate it into something far more functional and comfortable. Whether it’s an old garage, an outbuilding, or a dated bungalow, our team brings the skills and creativity to transform underused spaces into quality secondary dwellings you’d be proud to offer a family member.

Backyard Granny Flats

Make use of a large or underutilised backyard by adding a granny flat that sits comfortably within the landscape without overwhelming the main home. We design each backyard build to complement the existing architecture and garden, creating a space that feels like a natural part of the property.

Tennis Court Conversions

A surplus tennis court is one of the most underutilised assets on larger Northern Beaches and North Shore properties. Converting one into a granny flat, studio, or secondary dwelling is a smart way to add value to your land and create genuinely liveable space for your family.

Pool Houses & Guest Studios

Not every secondary dwelling needs to be a full granny flat. We build pool houses, self-contained guest rooms, and studio bungalows that give visitors or extended family their own space while sharing the same beautiful property.

Granny Flat + Deck or Pergola

Complete the picture with an outdoor space to match. We regularly combine granny flat builds with a new deck or pergola, creating a complete living environment that makes the most of the Northern Beaches climate and your block’s potential.
