“We build HOMES, not just houses.”
Our motto is all about creating a home unique to our clients, their needs and lifestyles.

It's also about the fact that we are a tight knit team that puts a lot of love and thought into every single one of our builds.

Astro Builders is passionate about designing and creating high quality, custom architectural homes. Our aim is to add not only to our clients' quality of life, but also all our employees' lives as well.

Originally founded in 2014, Astro Builders is already known for its dedication to creating fully custom, bespoke homes for its clients. Astro Builders is proudly NZ owned and operated. All our home plans are created to suit New Zealand's world famous environment. 



Here at Astro Builders we pride ourselves on our honesty and solid work ethics. 

We're known for being flexible, hard-working, having an eye for quality work and for our custom home designs.

We love serving our clients by giving them a highly customised experience that takes a lot of the stress out of building and gives it a healthy dose of fun and adventure! We love taking our clients on a journey. We're with them every step of the way through the build, from the design process to selecting hardware and paint colours, we're there.

We not only create custom turn-key homes where we handle every aspect of the build for our clients - but if you're a qualified electrician for example and want to do your own wiring, then we have options available to accommodate you as well!

We are upfront about your options while still being flexible. So you don't have to worry about being pressured into upgrades you don't want while still knowing exactly what your options are if you decide that is the route you want to go.



Caleb is the founder of Astro Builders as well as:

  • A fully licensed and certified builder with 13+ years experience in the industry

  • Partner to Amyrah and father to two high energy tamariki

  • Squash player

  • Fishing kayaker


Astro Builders was founded out of his desire to have the freedom to be creative with his skills and designs by designing customs homes for his clients, as well as the opportunity to work towards better work hours for him so that he could spend more time at home with his young whānau while also supporting his partner, in her art career.

Thank you for supporting this kaupapa!
