Smarter buildings for New Zealand.
We're a Kiwi-owned company on a mission to make quality buildings faster, simpler and more affordable — without cutting corners.
Flexible buildings that are faster, more affordable, and more practical.
Expanders® started with a simple idea: creating flexible buildings that are faster, more affordable, and more practical than traditional construction.
After seeing how slow and expensive conventional builds had become in New Zealand, we began exploring expandable building systems used internationally — structures that could be delivered, installed, and lived in far quicker than traditional builds.
What started as a small operation has grown into one of New Zealand’s most recognised expandable building suppliers, with 400+ buildings delivered across 9 countries.
Today Expanders® works with NZ-based engineers, architects and installers to ensure every unit meets local expectations while remaining accessible and affordable.
Trusted by hundreds of Kiwi homeowners.

Our journey
While living on the Gold Coast, Australia, Shad (Founder) was working in marketing for transportable building company. Expandable buildings were already popular in Australia, but very few people in New Zealand knew about them. Seeing the potential for a faster, more affordable transportable building solution back home, the idea for bringing expandable buildings to New Zealand began to take shape.
Expanders® was founded with the goal of making building more affordable and accessible. Shad returned to Christchurch to establish the company, working alongside trusted friends and industry professionals including builders, electricians, plumbers, architects and engineers to bring expandable buildings to the New Zealand market.
As demand grew quickly, Taylor and Shanae joined the team to strengthen operations and customer support. Expanders® attended its first major trade show, the Christchurch A&P Show, where the buildings were a massive hit with long queues of visitors. With demand rising, the Christchurch warehouse and operations base was established, and over 100 buildings were delivered across New Zealand and the Pacific Islands throughout the year.
To support growing demand and improve quality, Expanders® upgraded its overseas production facility to a purpose-built $11 million factory with modern machinery and advanced manufacturing. The buildings have been refined and upgraded more than 16 times based on customer feedback and New Zealand conditions, fixing issues like leaking and non-compliant materials. Expanders® also secured an exclusive distribution agreement to be the sole distributor of these New Zealand-optimised buildings across the Pacific region.
In 2026, Expanders® was awarded a contract with the Government of Kiribati to supply 16 expandable buildings, marking an exciting international milestone. A new Auckland location also opened to better serve North Island customers. As demand for flexible, affordable transportable buildings continues to grow, Expanders® remains focused on improving its transportable buildings, expanding its reach and helping more people across New Zealand and the Pacific access practical living solutions.
