Question 1

How much does a granny flat cost in Australia in 2026?

Accepted Answer

E2ES fixed prices: 30 m² Compact Studio $110,000 + GST. 60 m² Two-Bedroom $170,000 + GST. 60 m² Dual Living (two independent studios on one footprint) $200,000 + GST. Cash down is ~20% of build cost (~$32k–$52k); the other 80% is a construction loan secured against the new building. All three include permits, slab, frame, cladding, roof, insulation, kitchen, bathroom, flooring, AC, hot water, plumbing and electrical rough-in, and connection to existing mains within 10 m sewer / 15 m cabling.

Question 2

What is the cheapest granny flat builder in Melbourne?

Accepted Answer

E2ES's 30 m² Compact Studio at $110,000 + GST is among the cheapest fully-finished granny flats in Melbourne — fixed price, no upsells, including permits and connections. Cheaper quotes exist but typically exclude permits, finishes or connection costs that add $20k–$40k once site conditions are tallied. The fixed-price guarantee at signing is the differentiator.

Question 3

What is a granny flat?

Accepted Answer

A granny flat (also called a secondary dwelling, ancillary dwelling unit, ADU, backyard studio, or backyard cabin) is a fully self-contained secondary residence built on the same lot as the main house. In Australia it sits on a single title (no subdivision), is Class 1a compliant under NCC 2022, and can be either lived in by family or leased to a tenant for rental income.

Question 4

How long does it take to build a granny flat?

Accepted Answer

30 m² Compact Studio: fixed 3-month construction window. 60 m² Two-Bedroom: 12–14 weeks. 60 m² Dual Living: 14–16 weeks. End-to-end (from contract to first tenant) takes ~5–8 months including permit and leasing stages.

Question 5

Do I need council approval for a granny flat?

Accepted Answer

Yes, almost always. Most E2ES projects use a Class 1a Building Permit (4–8 weeks). In NSW, lots ≥ 450 m² can use the Affordable Rental Housing SEPP Complying Development pathway (~10 days, no neighbour consent). Heritage Overlay or DCP/DCPO sites add 6–12 months. E2ES handles the entire permit process — owner has zero paperwork.

Question 6

Can I rent out a granny flat as a separate lease?

Accepted Answer

Yes. All E2ES designs are Class 1a self-contained dwellings, which means up to 3 leases per lot (NCC 2022 Class 1b threshold) without requiring a rooming-house licence. The 60 m² Dual Living layout is two fully independent studios on one footprint, each leasable as a standalone tenancy.

Question 7

What is the rental yield on a granny flat?

Accepted Answer

Gross yields on build cost: 30 m² studio ~16.3% ($380/wk on $110k), 60 m² two-bed ~13.9% ($500/wk on $170k), 60 m² dual ~16.5% ($700/wk on $200k). Net yields on cash down are significantly higher (~33% on the 30 m²) because 80% of the build is financed via construction loan, leveraging the owner's existing land equity.

Question 8

Can I build a granny flat in Brisbane / Gold Coast / Sydney?

Accepted Answer

Yes. E2ES operates across Melbourne, Brisbane, Gold Coast and Sydney. Brisbane and Gold Coast follow the Queensland Development Code MP1.1 (Secondary Dwelling) — typically 400–600 m² minimum lot. Sydney uses the NSW Affordable Rental Housing SEPP 2009 (450 m² minimum, 10-day Complying Development). All four cities use the same three E2ES floor plans.
