The straight answer

Researched 15 Oct 2026 from Modify's own site and the public registers.

Who they are

Modify is the trading name of Outback Building Group Pty Ltd, a family business in Murray Bridge, South Australia, run by directors Luke Angel and Marcus Rayner. It started as Out-Back Portable Buildings in about 2020, and the current company dates from November 2022. It builds homes, granny flats, cabins, offices, classrooms and worker accommodation, and says it is a Master Builders Association member.

What they make

Steel-framed transportable buildings on a skid base, with frames roll-formed in house on FRAMECAD equipment from BlueScope steel. The residential range runs from a 6 x 3 m Compact Retreat with bathroom through Cozy and Casa plans to Premium Casa homes of 12 x 6 m with three bedrooms, and every plan can be changed or joined into larger layouts. Standard cladding is Panel Rib or Custom Orb Colorbond, with James Hardie as an option.

What the price covers

Modify publishes no prices; each building is quoted. Its FAQ lists council approval, delivery, earthworks for the pad, plumbing and electrical connections, and septic where needed as extra costs. Delivery is priced by distance from Murray Bridge, building size and site access.

Installing one in Queensland

Modify builds in South Australia and delivers by truck and crane; its transport team lays and levels blocks, with tie-downs or steel piers as options. It is not on the QBCC register and names no Queensland builder, so a Queensland buyer needs a QBCC-licensed builder for footings, tie-downs and connections and a private certifier for the Class 1a approval. Transport from Murray Bridge to SEQ is a long haul, so get the delivery quote early.

Who it suits

Buyers who want a custom steel-framed transportable and are prepared to engage their own Queensland builder for the site work.

Worth checking

Get a delivered price to your address in writing, and line up a QBCC-licensed builder before you pay a deposit. The site leans on the directors' 'over two decades' of experience, while the business itself dates from about 2020. One page claims customers made '30-50%' returns and offers a buyback guarantee; ask for those terms in writing.

LicenceOUTBACK BUILDING GROUP PTY LTD (ACN 663 749 166) is not on the QBCC register (active, cancelled or suspended lists). The SA Consumer and Business Services licence register sits behind a robot check, so an SA building work contractor licence could not be confirmed. The site claims Master Builders Association membership but gives no licence number. Modify manufactures in SA and delivers; no Queensland builder is named for the install.

TradingA Dec 2022 local news piece said the business (then Out-Back Portable Buildings) had been 'in business for almost three years', so since about 2020; current company ABN since 23 Nov 2022; MODIFY business name since 23 May 2024. The site's 'over two decades' refers to the directors' experience, not the company.
