Start with an empty field, a large backyard for a secondary dwelling, lift up your existing home or build in under your high set house Mates Rates Building has experience in all.

We can ensure your job runs smoothly from start to finish making your design ideas a reality or offering guidance where needed to optimise your dollar value per square metre. While the conventional way to extend your house may be to go up or out, the reality is that there is another option, one that Queenslanders have been doing for decades; go under. Mates Rates Building can assist you in gaining another level to your home by rising up, or digging down.


Mates Rates Building has developed a building process which takes into account our clients’ needs: in most cases you will be able to live in your home while build under and we make every reasonable effort to minimize disruption to your living arrangements. Additionally, our carpenters work exclusively for us, giving you added peace-of-mind and security.
