Auckland Interior Design Studio

Auckland’s collaborative interior design studio for architectural new builds and renovations.

For more than 20 years, Trinity Interior Design has partnered with architects and builders across New Zealand on residential interior design, from architectural new builds and whole-home renovations to considered furnishing and styling projects. We work alongside your project team from the earliest design stages, so interior decisions and architecture develop together, rather than being resolved separately.

 

WHERE INTERIORS AND ARCHITECTURE ALIGN

 

A COLLABORATIVE PARTNER

We join the discussion early when interior decisions can shape the outcomes of the home. From slab set-downs to window treatments and storage areas, we guide the right conversations at the right time, ensuring decisions are timely and aligned. Our work bridges architecture and construction, enabling everyone to move forward with confidence.

 

KEEPING THE VISION INTACT

With comprehensive CAD drawings, shared communication platforms, and hands-on coordination, we ensure that what is designed is what gets delivered. We work with the architect’s drawings, dovetailing seamlessly into their plans. And track the important details – from product selections and ordering to site deliveries – so nothing is missed.

 

A DESIGN JOURNEY THAT FEELS AS GOOD AS THE RESULT

We take the stress out of decision making to remove the sense of overwhelm. We map out key milestones from the very start so decisions are layered and unhurried, information is delivered at the right time, and everyone knows what’s next.

Trinity has made a significant contribution to many of our architectural projects over the years. We share values of teamwork, and this collaborative approach ensures the interior design is consistently harmonious with our architecture.
