datum projects offers full service solutions


For nearly a decade, Datum Projects have been making life easy for brands, consultants, and contractors alike. Born from a desire to work in a more client-centric and solutions-driven environment, founder (and active player in the company) Seth Gleeson leveraged his 25+ years of retail and commercial fit-out experience to launch a business focused on great people and great service.

Since then, what started with catering and shop fit-outs in the greater Auckland area has expanded to retail, commercial, hospitality, and medical fit-outs across the country – including award-winning and New Zealand-leading sustainable projects.

With a specialist team of experienced experts across various trades and a thriving in-house joinery factory, Datum Projects offers full-service solutions and advice on all aspects of the fit-out process. Our people care about doing an epic job because we care about our people – we like to surround ourselves by the best, so we give them awesome opportunities and treat them like family.

We’re damn proud to be recognised as one of the major players in the industry, with a reputation built on enthusiastic referrals and a legacy of always doing the job right. We’re efficient, innovative and service-focused. That’s how we make interior fit-outs easy.

Following in his father’s footsteps in owning a shopfitting company, Seth oversees all project delivery – bringing a calm demeanour and top-notch problem solving to a fast-paced industry.
