What STACK Interiors does

STACK Interiors is a privately held New Zealand commercial interior design firm headquartered in Auckland at 20 Beaumont Street, Freemans Bay. Founded in 1998 and operating for over 25 years, the company delivers workplace strategy, interior design, and project delivery services to mid-market and enterprise clients across New Zealand. Its service offering is structured as three integrated pillars: Strategy (workplace consulting and change management for hybrid and agile work models), Design (creative interior design, working drawings, specifications, and consent documentation), and Delivery (project management, construction administration, furniture procurement, quantity surveying, and compliance management). The firm operates as a direct-to-client professional services business with no intermediaries, selling project-based engagements sourced through portfolio visibility, awards, referral, and inbound web inquiries.

The firm is built around a multidisciplinary team of approximately 20 staff including design and construction professionals, designers, space planners, workplace strategists, technicians and quantity surveyors. Leadership comprises Managing Director David Gunn (25 years with the firm), Design Director David Plaistowe (PDINZ, DINZ Board), Director Project Delivery Daryl Howarth, and Head of Client Relationships Sheila Ye. STACK has completed more than 200 projects across a broad enterprise client base spanning legal, accounting, insurance, financial services, aviation, energy, utilities, telecommunications, healthcare, automotive, education, consulting and retail sectors, with named clients including UDC Finance, Qantas, Contact Energy, CBRE, One New Zealand, Lion, Vector, Wynn Williams, BDO, Boston Consulting Group, AA New Zealand, Tower Insurance and Mercedes Benz NZ.

Revenue is generated entirely through professional services fees tied to bespoke project scope, with no publicly disclosed pricing. The firm differentiates through deep NZ market tenure, an award-winning design portfolio (three 2025 Best Awards, 2025 Interior Award, 2025 Dezeen longlist), sustainability integration across operations and material selection, and culturally contextual design including Māori-inspired elements where appropriate. Go-to-market relies on portfolio-led content marketing, earned media (ArchitectureNOW, Dezeen), industry awards, and repeat-client referrals rather than paid acquisition. STACK has no parent company, no disclosed funding, and no subsidiary structure, operating as an NZ-owned independent.
