Meet our Board Members
Our Board is elected annually at the OffsiteNZ Annual General Meeting in June and represents a wide range of stakeholders and a wealth of exerience. OffsiteNZ Members are invited to nominate and vote for their preferred Board Member each year.
Craig Kellington is the Managing Director at Smart Solution Homes, a company designing, building and installing pre-finished homes throughout the Greater Auckland region.
After 10 years in the renovation industry, and with growing media talk about the need to build more houses, coupled with a real lack of skilled labour to select form, Craig's vision was to work smarter, not harder, and, in early 2017, the concept of Smart Solution Homes was born.
Originally from Scotland, Craig is a fully qualified carpenter/builder. He ran a successful renovation business for 8 years which was sold to put full effort into Smart Solution Homes.
Craig is focused on cost-effectiveness, sustainability, affordable housing and social development projects.
