Iain Wiebenga

Founder and Director

Iain is a registered builder and Greensmart® Professional, with over 15 years of experience in construction. He’s passionate about sustainable design and building strong, beautiful, and durable houses using locally sourced materials. As a proud green builder, Iain ensures that every project reflects a commitment to high-quality and sustainable practices.

Iain and his family — his beautiful wife Ange, their two girls Aspen and Revi, and Luna the wonder doggo — live in the peaceful little town of Moriac, in the heart of the Surf Coast hinterland. They enjoy the natural beauty of the area, which is a testament to the sustainable architecture and environmentally conscious construction that Iain champions.

Growing up in Mount Beauty, a close-knit community in the alpine regions of Dhudhuroa country, Iain has always appreciated the importance of caring for the environment. His upbringing fostered a love for the bush, family, and community. An outdoor enthusiast, Iain is an accomplished skier and mountain biker, and he loves to travel. Together with Ange, he has adventured across the globe to experience new cultures, sample incredible food, and create unforgettable memories.

Iain particularly enjoys working with sustainable materials, such as rammed earth. His dedication to innovative sustainable building practices is reflected in the core values of Keystone Construction Geelong, where they focus on delivering energy-efficient custom homes, including luxury sustainable homes and high-end custom renovations. This commitment is evident in the carefully considered home that he’s recently built for his young family, showcasing the principles of sustainable design and quality craftsmanship.
