Researched 15 Oct 2026 from Coast Modular's own site and the public registers.
Who they are
Coast Modular is a family business started by three brothers, with its factory and showroom at 40 Enterprise Avenue, Tweed Heads South, on the Queensland border. The company has traded since September 2023. It holds QBCC low-rise builder licence 15465753 and NSW licence 458362C, both current on the registers.
What they make
One, two and three bedroom modular homes, from the 32.8 m² Bottlebrush to the 132 m² Rosewood. The site focuses on floor plans, storage and low-maintenance finishes. Frame and cladding details are not published.
What the price covers
Prices are not published; the pricing and inclusions download needs your contact details. The site says homes are sold on a fixed-price contract covering design, approvals, site preparation, delivery and installation, with a quoted 10 to 14 week build.
Installing one in Queensland
Coast Modular builds in its factory while site works run in parallel, then trucks and installs the home itself as the QBCC licensed builder. The site does not set out footings, crane use or connections in detail, so get these written into the contract.
Who it suits
Gold Coast and northern NSW buyers who want one licensed company to run a turnkey modular job from design to handover.
Worth checking
No prices, warranty wording or Class 1a statement on the site, and a young company. Ask for the inclusions list, the warranty terms and the Class 1a approval path before paying a deposit.
No maker pays to be listed or ranked, and every list is sorted by price, never by who pays. This isn't every maker in the market yet: missing one? Say which. Prices and sizes are the makers' own, read from their websites on the date shown, and makers change them: check with the maker before you buy. Installed prices are estimates for an owner builder, inc GST, from the install cost calculator; a licensed builder adds about $10,000. Is a listing yours, or wrong? Claim it, fix it or have it taken down.
