Hickinbotham cuts home construction to 17 weeks in South Australian trial

South Australian home builder Hickinbotham has completed three four-bedroom houses in 17 weeks at Renewal SA’s Playford Alive development in Adelaide’s northern suburbs, in a trial aimed at reducing construction times through prefabrication and changes to conventional building practices.

According to the South Australian Government, which announced the results on 4 November 2026, the trial combined prefabricated building components with more closely coordinated construction schedules and early access to development sites.

The three single-storey homes, each comprising four bedrooms, two bathrooms and approximately 180 square metres of floor space, were sold to first homebuyers through HomeSeekerSA earlier this year.

Prefabricated modules enabled the frames, external walls and roofs to be completed within one month, with conventional building methods used to finish the interiors and remaining construction work.

Another factor was Renewal SA’s decision to allow Hickinbotham to begin construction while surrounding infrastructure, including roads, footpaths, water and electrical services, was still being completed.

This meant housing construction could proceed alongside civil works rather than waiting for the broader development to be finished.

Prefabrication forms part of wider productivity changes
Renewal SA said standardised floor plans, limited design variations and mass-produced layout modules were central to the accelerated programme.

The trial brought together several measures intended to reduce delays, including prefabrication, earlier site access and closer coordination between trades and contractors.

Hickinbotham Group Managing Director Michael Hickinbotham said the company was investing in its workforce, technology and production systems to improve construction productivity.

“We’re reversing decades of declining construction productivity and transforming the way we build homes by investing in our people, technology and production systems.”

“Most importantly, these productivity improvements can be replicated. Our ambition is to make four-month construction the standard.”

Hickinbotham also pointed to the relationship between land development and construction as an area where further time savings could be achieved.

“By better coordinating land development and construction, eliminating unnecessary waiting and improving flow, we can significantly accelerate housing delivery.”

The company has previously promoted a 24-week construction guarantee, although its current website also advertises an 18-week guarantee for eligible homes.

The 17-week result represents a further reduction, although the relative contribution of prefabrication, standardisation and revised site scheduling has not been quantified.

Established volume builder looks to shorten delivery times
Founded in 1954 by Alan Hickinbotham and his father, Alan R. Hickinbotham, the family-owned business has grown into South Australia’s largest residential building group.

According to the company, it has constructed more than 50,000 homes and developed over 60 residential estates during its 70-year history.

Hickinbotham Group was ranked Australia’s ninth-largest detached housing builder in the Housing Industry Association’s 2023–24 Housing 100 report and the largest residential builder in South Australia.

Its operations span residential construction and land development, with an extensive range of standardised home designs and house-and-land packages.

The Playford Alive project is one of several Renewal SA initiatives examining how different construction methods might accelerate housing delivery.

At Noarlunga, Renewal SA is working with South Australian manufacturer 5North, whose robotic manufacturing facility has a stated production capacity equivalent to 3,000 homes annually.

A separate project at Edinburgh involves five display homes assembled from modules manufactured in construction yards, transported by truck and reassembled onsite.

The Hickinbotham trial differs from these more extensively manufactured building systems, retaining conventional onsite construction while introducing prefabricated components and changes to the construction programme.

Whether the 17-week timeframe can be reproduced consistently across larger housing developments, and at what cost, will determine the broader significance of the trial.

For now, Hickinbotham has completed the three Playford Alive homes, with their first-homebuyer owners expected to move in shortly.
