Mark Suddens

Associate, Senior Draftsman / CAD Technician


Mark is a skilled CAD Technician with an excellent understanding of building detailing, coupled with a thorough approach to full documentation. Mark also has extensive experience as a construction contractor and project manager. After studying for a science degree at The University of Auckland in the 1980s, Mark explored his creative side and honed his business skills by starting and running a successful street fashion label, “Cabash,” with his partner, Bernadette. By the mid '90s (and somewhat burnt out by this enterprise) Mark moved in a new direction and teamed up with his father-in-law to develop (and patent) a panelized timber/plywood housing construction system. The ethos behind this was to make housing more affordable. By engaging in partnerships with third sector “not- for-profit” groups, and several hapū and whānau, Cabash Self-Build Homes Ltd was able to instigate several low-cost housing initiatives in various parts of the country. Mark has been working with designTRIBE since 2002 as a Senior Draftsman / CAD Technician, drawing on his construction and management skills to develop and work with integrated three-dimensional information modelling documentation.
