Low cost prefabricated house kits for owner builders.

MZ3 is a house kit supplier with a difference.

We are engineers and automated machine builders with 20 years machine building and 10 years building construction experience.

We have recently developed an automated machine to make low cost and high quality walls, floors and roofs that are thermally efficient and eco friendly.  


We use a fast transport and install system so your house can go up in as little as one day with minimal mess on site or disruption to your neighbours!

Building this fast cuts your loan interest and rent bills so you can pay off your mortgage faster.


Building a house is a very big decision so you should do all you can to get it right.
It is your house so you should also design it how you want it.

We will help you develop a basic 3D Solidworks model of your design enabling you to take a virtual tour of your house!
Check you are happy with your design - share it with your friends and family and get their input so you make no mistakes.

When you are happy with your design and you have council approval, we will make your house kit and our crew can install it for you through to lockup stage anywhere in the Perth metro area. You are always welcome to help on site!

Then finish and landscape your house in your time frame.

We make complete walls, floors and roofs to any system that is not double brick however we recommend using treated timber frame which is better thermally and environmentally than steel.
