Who they are
Superior Granny Flats is the trading name of Betnale Pty Ltd, a family business with its factory and showroom at Bayswater in Melbourne and a Queensland office and display at 3/6 Graham Street, Underwood. Betnale holds QBCC Builder Open licence 1285667 and has held its ABN since 2000. Its site cites more than 40 years in building and Master Builders membership in Victoria and Queensland.
What they make
Single-storey granny flats from a 24 m2 sleepout to an 84 m2 two-bedroom plan, in an 'Affordable' and a 'Superior' finish range on the same plans, plus a 60 m2 investor unit. Wall panels are prefabricated and assembled on site on a timber subfloor and steel stumps, with fibre cement weatherboards. Every plan is listed as 7 star energy rated, and plans can be changed, including for wheelchair access.
What the price covers
Unit prices run from $117,900 to $227,900; GST is not stated. Queensland jobs add $8,500 for design, approvals and certification and $19,900 for service connections within 28 m. Council DA fees, site preparation and upgrades to existing services are extra.
Installing one in Queensland
Superior builds the home on site with its own team as the licensed builder, so no separate installer is needed for the home itself. Panels arrive flat packed, which suits blocks with tight side access, and no crane is mentioned. The buyer pays separately for any DA, site preparation and longer service runs.
Who it suits
South East Queensland owners who want a conventional granny flat on stumps with a published price for every plan and a licensed builder that builds and connects it.
Worth checking
No warranty period is published, and the site gives more than one service connection figure. Get the warranty, the connection cost and the GST position in writing, and ask about the condition recorded on the licence.
