Novel SA interiors solution doubles revenue as businesses chase green cred
A South Australian company behind a novel building solution has found success overseas, as customers demand interior fit-outs that are good for the planet.
Adelaide-based modular wall system business XFrame saw its revenue more than double in the 2026 financial year on the back of strong demand for its interior fit-out solution.
This 118 per cent revenue growth scored the business – founded by managing director Carsten Dethlefsen and chief technology officer Ged Finch – the second spot in BDO’s Fast Movers list for 2026.
Fast Movers recognises SA’s fastest-growing and most innovative small-to-medium-sized companies.
The business was founded in 2019 to commercialise Finch’s industrial design research.
It sells a modular wall system made in Adelaide that is being used by office and retail clients for a variety of purposes: interior walls, change rooms and more.

Dethlefsen said the company was even working with the New Zealand government on a parliamentary building project, with reconfigurable wall frames being core to the interiors of the new building.
It is a success story built on a simple idea: “To reduce construction waste to landfill”, Dethlefsen said.
“It was a way of building a wall differently; a modular system,” he said, noting that the company’s proprietary software was the real growth arm of the company.

“We’re delivering a building solution, but it’s a tech platform that’s doing the heavy lifting.”
The co-founder said the company only started properly advertising its services last year, and that now XFrame was being “sought out by a lot of the big corporates that have internal fitout projects, but also have carbon budgets that they need to report against”.
The wall frames are made from plantation pine – sustainably grown timber that is harvested for this exact purpose.
“The carbon sequestration in the timber itself is very strong, but at the same time, we’re taking a sheet of construction-grade plywood and getting a very high yield out of it in terms of manufacturing,” Dethlefsen said.
“From a sheet of plywood, we get almost two square metres of wall frame out of it. It’s an incredibly efficient use of materials compared to traditional forms of construction.”
The likes of Uniqlo are using XFrame in-store now, and the company recently opened an office in Canada.
“We’ve now got a team employed directly there servicing that market,” Dethlefsen said.
“We’re starting to see some opportunities come out of the US as well.”
In terms of opportunities downstream, Dethlefsen said XFrame was exploring how to sell the product directly to retail buyers.
The market will only continue to grow for XFrame too, Dethlefsen said.
“As those corporates are having to report against their carbon budgets, they’re going to have to find alternate solutions,” Dethlefsen said.
