As experienced builders in home extensions across Port Macquarie, we combine smart design thinking with skilled construction to deliver spaces that are cohesive, functional and built to last.

We work closely with you to understand your goals, navigate approvals and guide you through each stage — from design to completion — ensuring the end result enhances how you live, now and into the future.

I'm very happy with the side fence, constructed by WHG Projects. It was installed as an accurate reflection of my ideas, consideration of safety, and it compliments the landscape very well.

We contacted Ben in regards to some residential structural jobs in our home. Ben was fantastic from the get go, and was able to fit us in with short notice. Ben and his team were respectful, professional and honest workers! Nothing was too much of a hassle and Ben kept us in the loop throughout the process. We would recommend WHG Projects to anyone and will definitely use them again for future renovations!
My clients are extremely impressed with the home they purchased from these developers. Quality throughout and easy to do business with. Loved working with them as nothing was an issue during or after. Their work speaks for itself with design, quality and execution.

Ben and the team at WHG projects were awesome to work with. They were prompt in repairing my Mother’s pergola and roof area after a severe hail storm. Excellent communication and made my Mother feel very comfortable.
