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 the lowest fixed turnkey price in our July 2026 survey of Melbourne granny flat builders — fully finished, permits and connections included, on an engineered concrete slab. Surveyed competitors' entry turnkey prices start around $133k, and independent 2026 guides put a finished 2-bed at $150k–$255k all-in. Cheaper stickers are kit shells or portable units on steel stumps, or exclude permits/connections/appliances that add $20k–$60k once tallied.

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

2 months from decision to finished build: ~1 month of paperwork (design + building permit — no planning permit needed on most Victorian lots under the small second dwelling reform, Amendment VC253) + ~1 month of construction on site (4 weeks; 4–5 for the Dual Living). Typical Melbourne builders quote 4–7 months. A tenant typically moves in 2–3 weeks after handover.

Question 5

Do I need council approval for a granny flat?

Accepted Answer

A building permit yes, a planning permit usually no. Victoria's small second dwelling reform (Amendment VC253, Dec 2023) removed the planning-permit requirement for dwellings ≤ 60 m² on lots ≥ 300 m² — E2ES's private surveyor issues the Class 1a Building Permit in 2–4 weeks, so paperwork closes in ~1 month. In NSW, lots ≥ 450 m² use the 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

Do E2ES granny flats sit on a concrete slab or steel stumps?

Accepted Answer

Always an engineered reinforced concrete slab (AS 2870.1 Class M/H, waffle-pod or raft) with termite management — the same foundation as a full-size home, included in every fixed price. Portable and prefab units that undercut on price sit on steel stumps or a trailer chassis, which rent for less and are valued differently by banks.

Question 9

What materials does E2ES build with?

Accepted Answer

The best Australian-made materials in the market, locked into the contract by brand: BlueScope Colorbond steel roof (Lysaght Klip-Lok 700), James Hardie Scyon Axon fibre-cement cladding, CSR Bradford Gold insulation, Australian MGP10 H2 termite-treated pine frame, silica-free engineered stone benchtops, double-glazed aluminium windows.

Question 10

Does E2ES have real multi-lease / room-by-room rental experience?

Accepted Answer

Yes. OptimaRea, E2ES's property-management arm, runs 300+ tenancies including dual-living and multi-lease setups — separate leases, separate bonds, sub-metered utilities. All Class 1a compliant: up to 3 leases per lot with no rooming-house licence. The 60 m² Dual Living plan was designed from that operating experience.

Question 11

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.
