About NEX 

Building Group.

The NEX Building Group has set a new standard in quality, residential housing for Australian families. Affordability, unbeatable value, innovative designs and exceptional customer service combined with the fact that each of our businesses offers something special and unique to our customers, has allowed us to lift the bar in new home building across the entire industry.

We know the decision to build a new home is most likely the biggest decision a person will ever make; they do so to improve their family’s way of life. We are passionate about building homes around people, not the other way around.

All our businesses operate under the same ethos – people are at the heart of everything we do.

If there is one thing we understand at NEX Building Group, it’s that our customers are the future of our business. Every one of our decisions is based on what is right for our customers, as we know that they will be right for the NEX Building Group, our staff and ultimately for all our stakeholders.

NEX Building Group is focused on designing a better life for our customers, we challenge convention and create brilliant homes for all Australians. We’ve been in business for more than 36 years and operate multiple businesses across New South Wales, Australian Capital Territory, Queensland, Victoria, Tasmania and South Australia.

In 2017, Asahi Kasei Homes, part of the Japanese Asahi Kasei Group, acquired 40 per cent of the NEX Building Group. During the following four years, this partnership flourished and saw the acquisition of Weeks homes and broad growth across the business. In April 2021, Asahi Kasei Homes acquired a further 40 per cent of the business, making them the majority shareholder. Managing Director Andrew Helmers retains his 20 percent share and continues to lead the business day-to-day. 

Through our partnership with Asahi Kasei Homes, we have access to world leading building design and building product technologies. Asahi Kasei Homes delivers approximately 8,000 buildings a year. Asahi Kasei Group has more than 40,000 employees around the world.

Our History.

The NEX Building Group has grown from early beginnings in 1987 as a family-owned new home building business based in the Hunter region of NSW, to become one of Australia’s most well-known and respected new project home, multi-residential and investment property building companies. 

Originally founded under McDonald Jones Homes, our continued focus on setting the benchmark in residential construction in Australia and providing our customers with a unique and exceptional building journey, has led to the evolution of our company and the development and establishment of new businesses within the NEX Building Group

In 2017, a strategic alliance was formed with Japan's Asahi Kasei Homes, and in 2021 Asahi Kasei Homes increased its shareholding, and today this is 80%. 

The NEX Building Group benefits from experienced leaders and a dedicated team of over 1,300 employees. Through our people's commitment, professionalism, knowledge, guidance and quality service, the Group is well-positioned to respond and overcome the challenges from the market and build on the solid foundations of the business

“We have the best job in the world, building new homes for Australian families.” - Andrew Helmers
