WHY CHOOSE US

TESTIMONIALS

"Working with Guy and Bron on the renovation and extension of our old stone home on the Yorke Peninsula was very enjoyable. From the first plan to the final door going in the communication and tradesmanship was great. Guy has so much experience in what looks good and how things fit. He organised everything from the start to the end.

We are really pleased with how our extension turned out. It is spacious and bright and easy to live in and blends well with the old part of the house. Many of the design ideas formed as the building progressed, using Guy’s knowledge and experience in building homes. I was very happy with the finishes both inside and out. He had excellent tradesmen who were prompt, very particular and neat and tidy.

No question went unanswered and Guy was always a phone call away. He always consulted me on all details before they were finalised.

We are really happy with the work done by G Jeffrey Construction."

"As first-time home builders, we were naturally nervous about the process, but working with Guy was an absolute pleasure from start to finish.

The communication was outstanding — clear, timely, and always reassuring — which made the entire experience smooth and stress-free. The quality of the build exceeded our expectations, and thanks to their proactive approach, there were no major issues throughout the project. It is lovely to see our plans come to ‘life’.

We are incredibly grateful for their professionalism and dedication, and we wouldn’t hesitate to recommend them to anyone looking to build their dream home."

“We couldn’t be happier with our experience building with G Jeffrey Construction. From the very beginning, Guy & Bronwyn were professional & approachable.

We really appreciated how they guided us through the design process . Guy had great suggestions and practical advice that made a big difference to the final result. His recommendations helped us create a home that not only looks amazing but also works perfectly with our lifestyle & coastal location.

We are absolutely thrilled with the result and so grateful to Guy for creating a home that feels even better than we imagined. We would confidently recommend them to anyone looking to build their dream home.”
