4 Key Features of Our Designs

Boutique Builder

We take on no more than 20 projects per year, giving you the time and attention you need to create a seamless experience.


Born out of the dual goals to help Australians become mortgage-free and to escape to the hinterland during the lockdowns, Mod Hauz is passionate about reinventing how we live.

Pre-Designed plans to choose from

With many designs ready to choose from, we have removed a lot of the upfront heavy-lifting, reducing your research & decision time.

Fixed Price – No Surprises

All plans offer a fixed price, influenced by factors like location, power proximity, distance from the Gold Coast, septic considerations, and landscaping.

6 unique floor plans to choose from, ranging from 25sqm to 72sqm, designed for BNB, to long term living, to guest houses.
