Question 1

How much does a granny flat cost in Australia?

Accepted Answer

Granny flat costs in Australia vary widely. A prefab expandable granny flat kit starts from around $22,490 (ex-factory base shell). Our aluminum modular granny flats start from $74,900 for a 32 sqm 1 bedroom unit, up to $279,900 for a 140 sqm 3 bedroom family home. Note that your total project budget should also include site preparation, transport, utility connections, and council/certifier fees — which can add $10,000–$40,000+ depending on your property.

Question 2

What is included in the prefab granny flat kit price?

Accepted Answer

Our expandable granny flat kit prices cover the factory-built unit at ex-factory price. This includes the structural shell, exterior panels, roofing, and (depending on the package) interior fit-out. Additional costs — freight, crane placement, site preparation, utility connections, and local certifier fees — are quoted separately based on your postcode and site conditions.

Question 3

How do prefab granny flat kits compare to traditional builds in cost?

Accepted Answer

Traditional granny flat construction in Australia typically costs $150,000–$250,000+ and takes 12+ months from design to move-in. Our prefab granny flat kits and modular homes are factory-built, quality-controlled, and delivered ready to install — significantly reducing both the cost and the timeline. Most modular granny flat installations are complete within days of delivery, not months.

Question 4

Do you support staged payments?

Accepted Answer

Yes. Projects typically follow milestone-based payment stages aligned to production, delivery, and handover. Exact terms are clarified in your project proposal and contract documents.

Question 5

Do I need council approval to build a granny flat?

Accepted Answer

In most Australian states and territories, some form of approval is required before installing a granny flat on your property. In NSW, many granny flats can be approved via a fast-track Complying Development Certificate (CDC) pathway without a full DA. In Queensland, Victoria, and WA the process differs. Requirements depend on your lot size, zoning, intended use (rental vs. family), and local council rules. We recommend confirming with your local certifier before committing to purchase.

Question 6

Can I build a granny flat on my property?

Accepted Answer

Most residential properties in Australia can accommodate a granny flat subject to minimum lot size requirements (typically 450–600 m² depending on state), setback distances, and site coverage limits. Properties in flood zones, bushfire-prone areas, or with heritage overlays may face additional restrictions. The best first step is to check with your local council or a private certifier.

Question 7

Are electrical and plumbing certifications included?

Accepted Answer

Final electrical and plumbing commissioning is completed by licensed local trades at your site. This is standard practice across Australia — it ensures your granny flat is certified to local standards by professionals who know your council and network. We provide compatible layouts and documentation to support the certification workflow.

Question 8

What is a CDC approval for a granny flat in NSW?

Accepted Answer

A CDC (Complying Development Certificate) is a fast-track approval pathway available for granny flats in NSW that meet the SEPP (Affordable Rental Housing) standards — typically lots over 450 m² in residential zones. CDC approval can be granted in as little as 10 business days by a private certifier, versus months for a full council DA. Our granny flat kits are designed to meet CDC eligibility criteria. Contact us to confirm your site eligibility.

Question 9

How long does it take to build a granny flat?

Accepted Answer

With a prefab granny flat kit, the timeline is dramatically shorter than a traditional build. Our expandable granny flat kits can be set up on-site in 1–2 days after delivery. Our modular aluminum granny flats are factory-built in 6–12 weeks and delivered as complete units ready to place. Total project time from order to move-in is typically 10–16 weeks, compared to 12–18+ months for a traditional build.

Question 10

How is a modular granny flat delivered and installed?

Accepted Answer

Our modular granny flats are precision-built in the factory, then transported to your site by truck. Single-module units (32–48 sqm) are craned into position in one lift. Multi-module units (62–140 sqm) are delivered in separate modules and connected on site. We can assist with logistics planning based on your property access and postcode.

Question 11

Can modular granny flats be installed in tight-access sites?

Accepted Answer

Many sites with constrained access can still be served with careful logistics planning — including crane positioning, route surveys, and overhead line checks. Share your property details early and we will flag any constraints before you commit.

Question 12

What is the difference between an expandable granny flat kit and an aluminum modular granny flat?

Accepted Answer

Our expandable (folding) granny flat kits are steel-frame units that open out on site — fast to install, very cost-effective, and ideal for investment properties where speed and ROI are priorities. Our aluminum modular granny flats are a premium product — precision-engineered aluminum alloy frames with panoramic glazing, premium interiors, and a wider range of sizes (32–140 sqm). Modular granny flats are better suited for permanent living, luxury rental, or architectural showcase.

Question 13

What granny flat size is right for me?

Accepted Answer

For a high-yield investment rental, a 32–48 sqm 1 bedroom granny flat is typically the most cost-efficient. For family use or long-term occupation, a 60–98 sqm 1–2 bedroom modular granny flat delivers more livable space. For a full family home, our 140 sqm 3 bedroom model is the flagship option. We can provide a recommendation based on your site, use case, and budget.

Question 14

How accurate is the initial quote?

Accepted Answer

The first quote gives a realistic range based on your inputs. Final pricing is confirmed after site access, postcode, and compliance variables are reviewed. We aim to be transparent about all cost buckets — unit price, freight, installation, and ancillary costs.

Question 15

Can I customise the exterior and interior of my granny flat?

Accepted Answer

Absolutely. Every granny flat is built to order at the factory — not pulled from stock. You can choose your exterior cladding colour and material (Colorbond, wood-look panels, rendered finish), interior colour scheme (Modern White, Warm Timber, Premium Dark, or custom), kitchen and bathroom layout, benchtop and cabinet finishes, flooring, lighting placement, and tap fixtures. We finalise a spec sheet with you before production starts.

Question 16

How do I track my order during production?

Accepted Answer

After your deposit is confirmed and production begins, we send you weekly photo and video updates directly from the factory floor. You will see your granny flat being built stage by stage — framing, cladding, interior fit-out, electrical, plumbing, and final QC. Before shipping, you receive a full pre-dispatch inspection report with photos. No black box — full transparency from deposit to delivery.

Question 17

What happens after I pay the deposit?

Accepted Answer

Once the deposit is received and your customisation spec sheet is locked in, your granny flat enters the factory production queue. Production typically takes 6–12 weeks depending on model and customisation complexity. During this period you receive weekly progress updates. The remaining balance is due before dispatch. We then coordinate shipping, delivery logistics, and on-site placement.
