Master Builders SA

GT Building Group
Clare Valley Distillery

“Craftsmanship, collaboration and creativity came together to deliver a truly distinctive build - one that is both grounded in its rural surroundings and refined in its execution. This bespoke gin cellar door redefines the 'shed conversion' aesthetic. Standard finishes were replaced with high-end alternatives - such as raw, clear-coat steel and hardwood battens. The result delivers warmth and permanence. The 100-year old cactus at the heart of the design wasn't just a feature, it was a key stakeholder and the builder took care to protect the site. The final result delivered exceptional value at $1 million less than competing tenders.”
