About DNA Building Group

We build for clients who value detail, clarity and steady communication. Our focus is premium renovations, custom carpentry, decking and outdoor structures across the Upper North Shore and Hills District.

DNA Building Group was founded in 2022 by Dave and Adamafter years of working together on site and in site-management roles. Their partnership started in 2012 when Adam began his apprenticeship under Dave at Homestead Home Builders. Dave entered the trade in 2002 and completed his Carpentry and Joinery in 2006, moving into site management in 2015. Adam followed into site management in 2021. They launched DNA in 2022 to deliver disciplined, transparent building for clients who care about the finish.
