About Us

ThermaBuild Homes are Built by Alexander Construction

Building awesomeness since 1947.

Alexander was founded by Ralph Alexander, who started the company in 1947, using an army gratuity he received on his return from World War II. Ralph had served as an infantryman in the Western Desert and had twice been made a prisoner of war (he escaped both times).

Upon his return home, he used that same grit and determination to start his own construction business. Initially, just one car and a custom-made, cut-down trailer transported the building materials to site, with Ralph running the carpentry and joinery shop from the family home in Georges Drive, Napier. A structure built from recycled ships' beams served as the workshop.

Driven by the same values, Alexander Construction continues today with a proud reputation for delivering quality residential and commercial projects. Our team brings together experienced builders, designers, and project managers who share a common commitment: to deliver every project on time, on budget, and to the highest standard of craftsmanship.

The original Alexanders team — our heritage of craftsmanship

Unity is the key to our success. We believe in the power of teamwork and collaboration, both within our organisation and in our partnerships with clients.
