Let's talk about Gemini Homes & the people that make up our family

A bit about us


GRAHAM Stritzke


I started Gemini Homes in 1994 right here in Mackay. I’ve been in the building industry since 1976. My initial trade was a Carpenter and Joiner. Prior to starting Gemini Homes, I was building in Mackay under my own name (G & D Stritzke Builders).

I recognised very early that Mackay was in need of quality building services. Mackay was a small town back then. Your reputation soon gets around if you are good. That’s why we adopted a policy of training apprentices (school based and adult) and encouraging associated trades to also take on apprentices.

As a result, I have some of the same tradespeople still working for us today, 20 years on. We have a collection of some of the best tradespeople in Mackay devoted to building to our very high standards. That’s why our building quality is second to none.




Brad Evans has been with Gemini Homes since 2002 and has been an integral part of helping the company grow to be Mackay’s largest new home builder. He is also our designer and estimator. With his design experience you are in good hands, he can tailor any plan to suit your needs.  Brad works closely with our sales staff to make any changes needed and oversees the contract and council approvals processes.


Katrina Cox


Katrina will guide you in the decision-making process for the selections in your new home. Katrina understands that your new home is a big investment and deciding your fixtures, finishes and inclusions can be one of the most exciting parts of building, or, one of the most stressful.  Using her experience and expertise choosing a beautiful interior is possible on any budget. From colours to flooring, kitchens and cabinetry, tiling and electrical plans, Katrinas product knowledge, passion for design and comfortable and easy manner will ensure you enjoy a stress free selections process and make the decisions that you will love living with for many years to come.
