Modular granny flats and secondary dwellings are one of the fastest-growing requests across regional Victoria — Geelong, the Surf Coast and the growth corridors. Here’s how EcoPrestige approaches them on cost, compliance and programme.
What a modular granny flat costs
EcoPrestige modular dwellings start from around $2,200/m² (excl GST). The final figure depends on size, layout, finishes and site access — but because the unit is manufactured in a controlled facility, the price carries far less weather and trade-sequencing risk than a conventional on-site build.
Compliance built in
Each unit is engineered to the National Construction Code with Australian engineering oversight and an Occupancy Certificate on completion — important for approvals and for resale or rental down the track.
Faster to finished
The module is built offsite in parallel with your site and services works, then delivered turnkey and fully pre-cladded for rapid assembly — roughly 30% faster than typical modular suppliers.

Frequently asked questions
How much does a modular granny flat cost in Victoria?
EcoPrestige modular dwellings start from around $2,200/m² (excl GST), so a compact granny flat is a cost-predictable addition compared with a conventional on-site build — with the same NCC compliance and a 12-year structural warranty.
Do modular granny flats need council approval?
Yes — like any dwelling they require the relevant planning and building approvals. EcoPrestige units are engineered to the National Construction Code with an Occupancy Certificate provided on completion to support that process.
How long does a modular granny flat take?
Because the unit is built offsite in parallel with site works, EcoPrestige delivers roughly 30% faster than typical modular suppliers, with the module arriving turnkey and fully pre-cladded.
Is it built to last?
Yes — structural steel, engineered to the NCC, with a 12-year structural warranty and a 12-month materials warranty.
