Sebastien builds as though the world depends on it.

He’s a Dutch-Australian architectural engineer and builder trained in cutting-edge Northern European sustainable design and construction. He leads all of our projects, supported by a capable and experienced team.

Sebastien has spent over a decade managing construction and remedial projects, mostly in Australia. He has led project teams repairing and improving poorly-constructed residential, strata and commercial buildings in several Australian cities. He has seen first-hand the effects of bad building design on people’s lives and livelihoods. These buildings were cold in the winter, and hot in the summer. They were expensive, energy inefficient, structurally unsound, and unfit to deal with the Australian climate.

He has advocated for improving Australian building standards among industry and in the media, including in The Australian, and is a member of the Master Builders Association of NSW.
