Oly Homes review: steel-framed modular from Yandina

Who they are

Oly Homes is a Sunshine Coast modular builder, the trading name of Bay Investments Qld Pty Ltd (ABN 92 103 649 814). Head office and factory are at 66 Pioneer Road, Yandina, with a second yard at Cooroy and a North Queensland office at 2 Mill Street, Mourilyan. They describe five decades in construction, starting at Yandina.

Managing director is Dale Funston and general manager is Steven Nousala. The site shows ISO 9001, ISO 14001 and ISO 45001 certification, and Dale Funston is listed as a Northern Territory registered building practitioner.

Their best-known job is eight modular homes for Thursday Island with the Uniting Church Queensland Synod and the Queensland Government's Housing Investment Fund. Built on the Sunshine Coast and shipped more than 1,700 km, it won the prefabricated and modular housing category at the 2025 Master Builders Far North Queensland awards, then the 2025 Master Builders Queensland award in the same category. It also took two HIA awards in Cairns, for steel frame and for modular and prefabricated housing.

In May 2026 they bought a 2.19 ha site at 14 and 34 Maurice Harvey Crescent, Corbould Park, for $9.855 million ex GST, for a 21,900 m² factory largely funded by the Commonwealth Bank. It is set to lift output from about 200 to about 550 homes a year, bring Yandina and Cooroy under one roof and create about 70 jobs. In August 2025 Dale Funston said they were booked out more than six months ahead.

What they make

Factory-built modular homes, from one-bed homes at the granny flat end to five-bed family homes. The home page lists 18 designs. The bedroom and bathroom counts below are from the design listings.

Floor areas and dimensions aren't labelled on the design pages; ask for the floor plan with areas. Designs feature verandahs, and some are elevated for sloping or flood-prone sites, the Cooloola for one. They also do custom builds, and are moving into medium density and two and three storey projects.

How they build

• High-strength steel frame made with Australian steel, which they say gives strength, termite resistance and fire safety.
• Built in their Yandina facility and delivered in sections. Partner brands on the site include Weathertex, James Hardie, Truecore steel, Laminex, YDL Stone, Taubmans, Haymes and Beaumont Tiles.
• Built to the National Construction Code, with the same approvals as a site-built home. Their FAQ says homes are permanent dwellings for ongoing residential use.
• Their FAQ notes higher wind classifications, such as cyclone ratings in northern Queensland and the Northern Territory, add cost.
• Energy rating: not published on their site; ask for it in writing.
• Timing: they say homes are ready in 8 to 10 weeks with modular construction. The Commonwealth Bank cited a two-bed, two-bath Oly home built and installed in nine weeks. Two seniors' homes for Thallon were built at Yandina over three months.

Price

Oly Homes prices on request. Their site talks about fixed, transparent pricing but doesn't publish starting prices. In October 2026 it advertised $10,000 in upgrades on a new Oly Home, ending 31 October.

What the price covers, going by their build process page: design guidance, council applications and site checks, building approval lodgement, engineering, the factory build, transport, installation, quality checks and handover. Ask for the quote to show the home and the site work as separate lines.

Finance

Oly Homes was among the first builders on the CommBank Assessed Manufacturers list. With an assessed manufacturer on a fixed-price contract up to $1.5 million, CommBank customers can draw progress payments up to 80% of the contract or 150% of land equity before the home is on site.

What's included, and what sits on top

• Approvals: Oly manages council applications and site checks, and lodges the building approval. If extra reports are needed, they tell you what's required.
• Transport, delivery and installation: Oly does these, then final checks and handover.
• Your side: make selections by the due date, get finance approved, provide proof of land ownership and ID, arrange site access, open power and water accounts, and organise boundary pegs or a survey if needed.
• Footings, connections and decks: their site doesn't say whether these are in the price; ask.
• Crane: their site doesn't say; ask.
• Cyclone-rated builds: priced higher, per their FAQ.

Where they deliver

Oly says it delivers across Australia. Published jobs run from the Sunshine Coast and Lake Macdonald to Kingaroy, Thallon, Mackay, Cairns and Thursday Island. The Mourilyan office covers North Queensland, and the Northern Territory registration covers work there.

Warranty and licence

Their site says the products they use are backed by warranty and mentions quality guarantees, but doesn't publish structural or workmanship warranty terms. Ask for them in writing.

Bay Investments Qld Pty Ltd, trading as Oly Homes, holds QBCC licence 1156073, active, Builder Open (register checked 13 October 2026). The licence number is shown on their site.

Getting one into the ground in Queensland

Oly Homes does approvals, transport and installation itself. These are the steps any modular home goes through here, so you know what's happening on your block.

1. Block check. Zoning, overlays (flood, bushfire, character, heritage), easements, where the sewer and stormwater run, slope, and whether a second dwelling fits under your council's rules.
2. Access check. The truck route in, overhead power lines, trees, and a firm, level spot for the crane within reach of the footings. Oversize loads can need escorts and road permits.
3. Approvals. A private certifier issues the building approval. If an overlay or the planning scheme triggers it, you need planning approval from council first. Expect a soil test and engineering for the footings.
4. Footings. Screw piles, bored piers or a slab, set out to the home's support points, built on site while the home is in the factory.
5. Transport and crane day. The modules are trucked in, lifted onto the footings and tied down.
6. Connections. A licensed plumber connects water, sewer and stormwater, and a licensed electrician connects power. Stairs, decks and ramps go on now if they're in the scope.
7. Final inspection. The certifier inspects and issues the final inspection certificate (Form 21 for a house or granny flat), with plumbing signed off separately.
8. Home warranty. Residential building work over $3,300 in Queensland must be covered by the Queensland Home Warranty Scheme. The licensed contractor who signs with you pays the premium to QBCC before work starts. Structural defect cover generally runs 6 years and 6 months.

Questions to ask them

• What is the floor area of the design I like, and what does the verandah add?
• What does the quote include: footings, crane, connections, stairs, decks?
• What energy rating does the design reach on my block?
• What wind classification are you designing to for my site?
• What structural and workmanship warranty do you give, in writing?
• How far out is your build slot today?
• Will my build be at Yandina or the new Corbould Park factory?
• What is the payment schedule, and can I use the CommBank progress payment option?
• Can I see a finished home or one in the factory?
